Edexcel A-Level Politics | Free Revision Notes
Estimated study time:Â 60 minutes
UK politics involves competition between several parties, even though Labour and the Conservatives have traditionally been particularly important at Westminster. This UK political parties in context A-Level Politics revision page examines the development of multi-party politics, its consequences for government, and the factors that help explain why parties succeed or fail. It also assesses the influence of the media on party fortunes. Edexcel specifically requires students to understand these relationships rather than treating party success as the result of one factor alone. This builds on the importance of smaller parties and prepares you for detailed study of electoral systems and party representation.

Revision Notes đź“š
What does Edexcel require you to know?
Section 2.4 of the Edexcel specification requires knowledge and understanding of:
the development of a multi-party system
its implications for government
the various factors that affect party success
explanations of why political parties have succeeded or failed
debates concerning the influence of the media.
This lesson therefore brings together several areas of UK Politics.
You need to make links between:
party competition → elections → representation → government
and:
party characteristics + voters + campaigns + political context + media → party success or failure
The Edexcel specification deliberately encourages these connections. Its wider voting-behaviour content identifies party policies, manifestos, campaign techniques, wider political circumstances and voter characteristics as factors that can help explain election outcomes.
What is a party system?
A party system describes the way political parties within a political system are grouped and structured.
The Edexcel glossary identifies several possible descriptions:
one-party dominant
two-party
two-and-a-half party
multi-party.
The label used depends on the pattern of political competition.
A two-party system is dominated primarily by two competing parties.
A multi-party system is one in which several political parties have meaningful electoral or political importance.
⚠️ A multi-party system does not mean every party is equally powerful.
Several parties can compete seriously for votes while two parties remain particularly important in forming Westminster governments.
The development of multi-party politics
For much of UK political competition, Labour and the Conservatives have occupied particularly powerful positions.
However, Edexcel materials identify a decline in their complete domination of voter choice alongside growing support for other parties.
The 2021 mark scheme, for example, states that support for many parties had become widespread across the UK and highlights the 2015 general election as evidence of this development. It contrasts this wider party support with the continuing ability of First-past-the-post (FPTP) to produce strong single-party governments.
This creates one of the central tensions of the topic:
The electorate can behave in an increasingly multi-party way while Westminster government remains heavily dominated by the largest parties.
Why has the party system become more multi-party?
The specification does not prescribe one fixed cause. Instead, the supplied materials support several related explanations.
Greater support for parties outside Labour and the Conservatives
The most direct evidence of multi-party development is increasing political support for alternatives.
This includes:
Liberal Democrats
regional parties
emerging and minor parties.
The significance of these alternatives was examined in how parties outside the established three can influence politics.
Smaller parties may:
win votes
secure representation
influence the political agenda
place pressure on larger parties
become important in devolved politics.
As a result, a description of UK politics based entirely on Labour versus Conservative competition can miss important parts of the political system.
Devolution and party competition
Multi-party politics is particularly visible outside Westminster.
The supplied Edexcel materials emphasise that devolved political institutions can contain a wider range of significant parties. This creates greater opportunities for parties other than Labour and the Conservatives to gain representation and political influence.
This means the UK does not necessarily possess the same party system at every political level.
The pattern of competition can differ between:
Westminster
Scotland
Wales
Northern Ireland.
This is one reason why describing the entire UK simply as a two-party system can be misleading.
Electoral systems and multi-party politics
Different electoral systems can affect how easily support for several parties is converted into representation.
FPTP is used for Westminster general elections. Under FPTP, winning seats depends on coming first in individual constituencies.
This can favour larger parties, particularly where their support enables them to win large numbers of constituencies.
More proportional systems can allow a wider spectrum of party support to appear in elected institutions.
However, the relationship is not automatic.
The 2022 examiner report warned students against assuming that proportional systems necessarily create successful coalitions or automatically explain the success of particular parties.
You will examine this relationship more closely when studying the operation and consequences of FPTP.
Multi-party voting does not necessarily mean multi-party government
This is a crucial distinction.
A country can have:
multi-party electoral competition
without necessarily having:
multi-party government.
Under FPTP, votes for several parties can still be translated into a parliamentary majority for one party.
The 2021 mark scheme therefore presents two competing arguments:
the growth of multiple parties makes Westminster representation less reflective of the range of voter choices
FPTP can still produce effective single-party governments capable of implementing manifestos and being held accountable.
So do not write:
"A multi-party system means coalition government."
That is too simplistic.
Implications of a multi-party system for government
Multi-party politics can have important consequences when electoral support is translated into parliamentary seats.
Coalition government
A coalition government is formed by more than one political party, normally accompanied by an agreement concerning policy and government office.
The Edexcel glossary gives the Conservative-Liberal Democrat coalition of 2010 to 2015Â as an example.
A coalition becomes relevant when no party has sufficient parliamentary strength to govern alone and two or more parties agree to govern together.
Potential consequences of coalition government
Coalition can produce:
policy compromise between parties
participation by more than one party in government
broader political representation within the executive.
However, parties may also have to abandon or modify parts of their preferred programmes in order to reach agreement.
This can affect how clearly voters can hold one party responsible for government decisions.
Minority government
A minority government enters office without possessing a majority of seats in Parliament.
The Edexcel glossary notes that this can make passing legislation difficult.
A minority government may therefore need support from politicians outside the governing party in order to secure parliamentary approval for its programme.
This gives other parties greater potential influence.
Support from smaller parties
A multi-party parliament can increase the importance of parties that are not themselves able to form a government.
The 2019 Edexcel materials used the Democratic Unionist Party (DUP) support arrangement at Westminster as evidence that a governing party may need assistance from another party.
This demonstrates an important effect of multi-party competition:
A party does not need to form the government to influence whether a government can operate effectively.
Multi-party politics and policy compromise
Where several parties are required to cooperate, policy may have to be negotiated.
This can be seen positively.
Compromise may:
incorporate more than one political viewpoint
limit domination by a single party
encourage cooperation.
However, it can also be criticised.
Compromise may:
weaken individual manifesto commitments
make responsibility less clear
make it harder for voters to identify which party is responsible for a particular decision.
The effect of multi-party politics therefore depends partly on whether you value compromise and wider representation more highly than decisiveness and clear accountability.
Multi-party politics and government stability
A common argument is that a single-party majority provides greater stability because one party possesses the parliamentary strength to pursue its programme.
The Edexcel materials contrast this with situations involving coalitions or minority governments. The 2021 mark scheme, for example, presents the ability of FPTP to produce single-party government as a potential advantage because a government can implement its manifesto and be clearly held accountable.
However, do not automatically assume that coalition government must be unstable or unsuccessful.
The 2022 examiner report specifically criticised answers that simply assumed coalitions should be avoided without analysing how successfully they might operate.
⚠️ Exam point: "Coalition = unstable" is an assertion, not an evaluation.
You need evidence and comparison.
Multi-party politics and mandates
A single-party majority may make the relationship between manifesto and government action clearer.
The governing party can claim a mandate for the programme on which it was elected.
In a coalition, different manifestos may have to be reconciled.
This can weaken the argument that one party's complete programme has been authorised by voters.
On the other hand, supporters of multi-party government can argue that compromise reflects the fact that voters themselves chose several different parties.
Multi-party politics and accountability
There is a similar tension concerning accountability.
Single-party government
Responsibility may be clearer:
one governing party → identifiable policies → voters can reward or punish it
Multi-party government
Responsibility may be shared:
several governing parties → negotiated policies → responsibility may be harder to assign
However, shared government can also mean that a wider range of political views is represented in decision-making.
The key examination skill is therefore to weigh:
representation and compromise
against:
decisiveness and accountability.
Does multi-party politics always weaken major parties?
No.
Even where support for multiple parties increases, Labour and the Conservatives can retain important advantages.
The supplied Edexcel materials identify:
established organisation
greater funding
electoral heartlands
the effects of FPTP
as factors helping the largest parties retain significant influence.
Therefore the UK party system can display both:
growing multi-party competition
and:
continued major-party strength.
These are not contradictory.
Factors affecting party success and failure
Edexcel requires you to explain various factors rather than identify one universal explanation.
Party success can be affected by:
Factor | How it can affect success or failure |
Policies and manifesto | Attractive policies may win support; unpopular policies may damage a party |
Leadership | Leaders may inspire confidence or damage the party's image |
Party unity | Unity can suggest governing competence; division can weaken trust |
Campaign organisation | Effective presentation and communication can strengthen support |
Governing record | Economic or political failures can damage an incumbent party |
Wider political context | Events before and during elections can shape voter priorities |
Funding and organisation | Resources affect a party's ability to campaign and communicate |
Electoral system | The system can make it easier or harder to convert votes into seats |
Voting patterns | Class, region, age and other voter characteristics can favour different parties |
Media | Coverage, bias, persuasion and opinion polls may help or damage parties |
No single factor necessarily operates independently.
For example, a leader's effectiveness may be partly determined by how the media portrays them.
Policies and manifestos
Political parties need policies capable of attracting voters.
A manifesto presents the party's intended programme and provides voters with information about what the party proposes to do if it gains power.
The importance of manifestos may increase when voters are less automatically attached to one party.
Edexcel's 2024 mark scheme argues that in a context of class and partisan dealignment, voters may pay greater attention to specific issues and manifesto content. It also notes that unpopular manifesto commitments can damage a party's electoral prospects.
This means policy can contribute to both:
success, when voters approve
and:
failure, when voters reject what is offered.
Policy is not always decisive
However, a strong manifesto cannot guarantee victory.
Voters may already have formed opinions because of:
the government's previous record
leadership
long-term party attachment
wider political circumstances.
This is why examination answers should avoid arguing that a single attractive policy automatically causes electoral success.
Instead ask:
How important was policy compared with competing explanations?
Leadership
Political leaders can become an important factor in party success.
The 2019 examination source presented the argument that successful leaders must be able to withstand media pressure and connect with voters, using Thatcher and Blair as examples.
Leadership can affect:
confidence in the party
public perception of governing competence
campaign communication
how effectively the party handles difficult events.
A leader can therefore become an important symbol of the wider party.
Leadership and governing competence
A party seeking re-election may be judged partly on whether voters believe it has governed competently.
The Edexcel voting-behaviour terminology includes governing competency, and examination materials repeatedly connect economic confidence and competence with electoral fortunes.
The 2023 mark scheme on the 1997 election, for example, identified declining public confidence in Conservative economic competence as one explanation for party failure.
This illustrates a wider principle:
A governing party is judged not simply on what it promises next, but on what voters think it has already done.
Party unity and division
Unity can contribute to success because it allows a party to present:
a clear message
coherent leadership
confidence in its direction.
Division can have the opposite effect.
Disagreement can make a party appear:
uncertain
internally conflicted
less capable of governing effectively.
The 2023 Edexcel materials use the 1997 election to contrast Labour unity with Conservative divisions, particularly over Europe.
The analytical chain is:
internal division → confused or negative public image → reduced confidence → possible electoral damage
However, division alone does not prove that a party will lose. Its significance needs to be weighed against policies, leadership, the government's record and the strength of its opponents.
Campaign organisation
Election campaigns allow parties to:
communicate policies
promote leaders
respond to opponents
focus attention on selected issues.
The 2023 mark scheme identifies Labour's professional and well-managed 1997 campaign as one factor contributing to the party's success.
An effective campaign can strengthen an existing advantage.
A poor campaign can expose weaknesses.
However, campaigns take place within a wider political context. A party that has already developed a deeply negative reputation may not be able to reverse it through several weeks of effective campaigning.
The wider political context
Political parties do not contest elections in isolation from previous events.
Party success may be influenced by:
the record of the incumbent government
economic confidence
political controversies
public perceptions of whether a party is in touch with voters
changing issues and priorities.
The 1997 Edexcel materials provide a clear illustration.
Labour's success can be linked to:
unity
campaign effectiveness
media relations
attractive political change.
Conservative failure can simultaneously be linked to:
division
economic weakness
damaging events and scandals
an image of being out of touch.
This demonstrates why elections usually have multiple causes.
Funding and organisation
Parties require resources to operate and contest elections effectively.
The supplied Edexcel materials identify a substantial advantage for larger established parties because smaller parties may struggle to match their funding and organisational capacity.
Funding can affect:
campaign organisation
communication
the ability to promote policies
the visibility of the party.
This does not mean that the richest party automatically wins.
However, resources may affect a party's ability to compete effectively.
The relationship between money and party competition is examined more fully in how political parties are financed.
Electoral systems
A political party's success can be measured in more than one way.
It may win:
votes
seats
government power
political influence.
An electoral system affects how votes are translated into representation.
Under FPTP, geographically concentrated support can be particularly valuable because each constituency is won separately.
A party can therefore gain substantial voter support without gaining proportionate representation.
This means that failure to win many seats is not automatically evidence that the party lacked voter support.
Safe seats and established support
The Edexcel glossary defines a safe seat as one where the incumbent holds a substantial majority and the same party tends to retain the constituency from election to election.
Safe seats can help established parties maintain parliamentary representation.
Traditional electoral support may therefore provide parties with a foundation that is difficult for opponents to dislodge.
However, voting behaviour can change.
The 2019 election materials explicitly raise the possibility of greater voter volatility and challenge the assumption that class, region or longstanding party alignment always make results predictable.
Voting behaviour
Party success ultimately depends on voters.
The Edexcel specification requires students to understand influences including:
class
partisanship and voting attachment
gender
age
ethnicity
region.
This means a party can succeed because its support matches important patterns in the electorate.
Equally, it can fail if traditional supporters move elsewhere.
This relationship is examined in much greater detail in social and demographic influences on voting.
The media and party success
The media is specifically named in section 2.4 as an area of debate when explaining party success and failure.
The wider Edexcel specification requires assessment of:
the role and impact of the media
opinion polls
media bias
persuasion.
The key word is assessment.
You should not simply state that the media decides elections.
You need to evaluate how powerful it really is.
How the media may help a political party
Positive or favourable media treatment may:
increase the visibility of a party
present its leader positively
draw attention to policies
reinforce confidence in the party
communicate campaign messages to voters.
The supplied Edexcel materials use Labour in 1997 as an example.
They identify Labour's efforts to gain a less hostile press environment as one factor supporting its electoral success.
This suggests that parties themselves believe media relationships matter.
How the media may damage a political party
Negative coverage may:
focus attention on party mistakes
damage a leader's image
expose divisions
amplify campaign problems
undermine public confidence.
The 2019 source presents the argument particularly strongly, stating that the media can "make and break" a political party and that leaders need to cope with media pressure.
The important analytical point is not simply that negative stories exist.
It is:
negative portrayal → changed or reinforced public perception → possible effect on party support
Media bias
Media bias concerns whether political coverage favours or disadvantages particular political positions or parties.
Bias can matter because voters receive much of their political information through media coverage.
If one party receives favourable treatment while another receives persistent criticism, this may affect the political environment in which both parties compete.
However, bias does not prove persuasion.
A media outlet may support a party because its audience already shares similar political preferences.
This leads to the crucial question:
Does the media change how people vote, or mainly reinforce attitudes they already hold?
Persuasion
Persuasion involves media content contributing to a change in political preference.
If media coverage persuades voters, its influence on party success could be substantial.
However, voters are also influenced by:
party identification
social characteristics
policies
leadership
economic and political events.
It is therefore difficult to isolate the media as the only cause of a political choice.
A stronger answer says:
media coverage may influence the way other political factors are interpreted
rather than:
Reinforcing existing preferences
Media influence may operate by confirming attitudes rather than changing them.
For example, people may choose political media that already reflects their views.
In this case:
political preference → media choice
may be just as important as:
media choice → political preference.
This weakens simplistic claims that a newspaper or broadcaster directly determines electoral behaviour.
Opinion polls
Opinion polls are also part of the media debate.
They can affect parties as well as voters.
The 2021 examination materials identify several possible effects.
Polls may:
show changes in party support
influence how parties campaign
lead parties to reconsider policies
influence turnout
encourage tactical voting.
However, polls may also be inaccurate or misleading.
Therefore polls can:
reflect political opinion
but may also:
affect political behaviour.
This two-way relationship makes them particularly useful in evaluation.
Opinion polls and party strategy
A party that sees support falling in opinion polls may:
change campaign emphasis
concentrate attention on different issues
adjust policy presentation
intensify campaigning.
The 2021 examiner report specifically noted that stronger analysis should explore how parties may alter policy when opinion polls suggest they could lose support.
This means media influence is not restricted to voters.
It can also change party behaviour.
Is media influence exaggerated?
There are strong arguments that it can be.
Voters may already have decided
Some voters have political preferences that existed before an election campaign begins.
Long-term influences may therefore outweigh campaign coverage.
Political events may matter more
Economic and political developments occurring before an election may shape party reputations more powerfully than media presentation during the campaign.
Policies may matter more
A party cannot rely entirely on favourable media treatment if voters reject its programme.
Leadership may matter more
The personality and perceived competence of political leaders may themselves drive political support.
Social and demographic factors may matter more
Class, region, age and other characteristics can continue to influence voting behaviour.
The media therefore operates alongside other factors rather than replacing them.
Or does the media shape how other factors are understood?
The strongest argument for media importance is often not that the media creates every political attitude.
Instead, the media may be important because it provides the lens through which voters encounter other factors.
For example, voters often learn about:
leaders
policies
manifesto announcements
campaign mistakes
opinion polls
party divisions
through media coverage.
The 2024 Edexcel mark scheme explicitly presents this argument, suggesting that media coverage may promote or damage a campaign and therefore affect how voters interpret campaign events and manifestos.
This makes the relationship interactive:
political event → media coverage → voter interpretation
rather than:
media → voter.
Comparing factors affecting success
A useful revision framework is to classify factors into three groups.
Party-controlled factors
These are factors over which the party has substantial influence:
policies
manifesto
leadership presentation
party unity
campaign organisation.
Structural or long-term factors
These are harder for a party to change quickly:
electoral system
safe seats
established voting patterns
party resources and organisation.
Contextual factors
These depend on circumstances surrounding an election:
government record
economic confidence
political events
media coverage
public priorities.
This helps you avoid simply producing a list.
Instead, you can ask:
Which type of factor is most important, and why?
Factors can reinforce each other
Party success rarely comes from one isolated cause.
Consider the following chain:
attractive policies → effective campaign → positive media presentation → strong leadership image → increased confidence
The reverse can also happen:
party division → negative media attention → weaker leadership image → falling confidence → electoral failure
This is why Edexcel questions often reward comparison between explanations.
The 1997 election as an example of interacting factors
The supplied Edexcel materials make 1997 particularly useful for understanding party success and failure.
Labour's success was linked to:
improved media relations
unity
effective campaigning
political rebranding
appealing issues and policies.
Conservative failure was linked to:
internal divisions
economic difficulties
damaging controversies
appearing out of touch
a weakened reputation in government.
The point is not that every election follows the same pattern.
The lesson is that success and failure are normally produced by competing and interacting explanations.
You will examine this election separately in the detailed 1997 case study.
How to evaluate which factor matters most
For each factor, ask four questions.
1. What is the mechanism?
How could this factor actually change party support?
For example:
party division → reduces confidence → voters move elsewhere
2. What evidence supports it?
Use a relevant election or party example.
3. What competing explanation exists?
For example:
Was Labour's 1997 success mainly caused by media support, or did Conservative failure matter more?
4. Which explanation has greater weight?
Explain why.
For example:
Media support may have helped Labour communicate its message, but Conservative economic and political weakness may already have created favourable conditions for opposition success.
That final comparison is AO3 evaluation.
Does the UK now have a multi-party system?
There is no need to treat the answer as completely binary.
Evidence supporting a multi-party description
several parties attract meaningful political support
regional parties are important
devolved politics contains broader party competition
smaller parties can influence larger parties
coalition and support arrangements demonstrate that other parties can matter.
Evidence against a fully multi-party description
Labour and the Conservatives remain especially important at Westminster
FPTP can favour larger parties
the two largest parties possess major organisational and funding advantages
single-party government can still result even when several parties receive substantial support.
The strongest conclusion is therefore often:
UK electoral politics has important multi-party characteristics, but these are filtered through institutions that can continue to give the largest parties disproportionate importance in Westminster government.
Does multi-party politics make government less effective?
Again, the answer depends on your criterion.
Argument that it may reduce effectiveness | Argument that it may improve government |
Coalition may require compromise | Compromise may represent more voters |
Minority governments may struggle to pass legislation | Other parties can scrutinise and influence policy |
Accountability may become less clear | Power is less concentrated in one party |
Manifesto commitments may be modified | Policies may reflect negotiation between different views |
Government formation can be more complex | Wider party representation may improve legitimacy |
Avoid assuming that decisiveness automatically equals good government.
Equally, avoid assuming that broader representation automatically produces effective government.
You need to establish the criterion you are using.
How important is the media compared with other factors?
A strong overall evaluation recognises three possibilities.
Media as the dominant factor
You could argue that:
media coverage determines how voters encounter campaigns
favourable treatment strengthens parties
hostile treatment damages leaders
opinion polls can shape both voters and party strategy.
Media as a secondary factor
You could argue that:
economic and political context is more important
policies and leaders generate the events that the media reports
long-term voting behaviour already shapes preferences
media influence may reinforce rather than change views.
Media as an amplifier
This is often the most nuanced interpretation.
The media may be especially powerful when it amplifies strengths or weaknesses produced elsewhere.
For example:
party division already exists → media repeatedly highlights it → public perception of division becomes stronger
or:
popular leader already attracts support → favourable coverage expands their visibility
The media is therefore important without necessarily being the original cause.
Overall judgement
UK politics has developed significant multi-party characteristics because voters increasingly support a wider range of parties and because regional and devolved politics has expanded the political importance of parties outside Labour and the Conservatives.
However, multi-party competition does not automatically produce multi-party government. FPTP and the organisational strength of major parties can still produce or favour single-party government.
Party success itself has no single explanation. Policies, leadership, unity, campaigns, governing competence, voter behaviour, resources, electoral systems and the wider political context can all matter.
The media is potentially powerful because it can influence how voters see many of these other factors. However, it is usually strongest when understood as part of a wider explanation rather than as a force that independently determines election outcomes.
This topic therefore leads naturally into detailed study of how the media influences political behaviour and how different elections demonstrate changing causes of party success.
Hints from the Examiner Reports đź’ˇ
Examiner hint:Â Do not reduce the party system to Westminster elections alone. The 2019 examiner report found that stronger answers considered devolution, coalition government, support arrangements and the influence of smaller-party ideas, while weaker answers focused too narrowly on FPTP and Westminster voting.
Examiner hint:Â Do not assume coalition automatically means unsuccessful government. The 2022 examiner report criticised answers that simply treated coalition as undesirable instead of examining how well particular arrangements operated and comparing compromise with single-party government.
Examiner hint: Use the media in its wider sense. The 2021 examiner report found that stronger answers considered different forms of media, while weaker candidates relied too heavily on old newspaper examples. Your analysis should address both bias and whether the media can actually confirm or change political preferences.
Examiner hint:Â Develop the link between evidence and party success. Do not simply write "the media supported Labour" or "the Conservatives were divided". Explain the mechanism, for example why favourable coverage might strengthen confidence or why division might make a party appear less capable of governing.
Examiner hint:Â Pair competing explanations. The 2023 examiner report found that directly comparing arguments, such as media influence against policy, party unity or the government's weaknesses, strengthened analysis and made substantiated judgements easier.
Examiner hint:Â Keep AO3 running throughout your essay. The 2019 examiner report repeatedly found that weaker candidates saved evaluation until the conclusion. Stronger responses established a position early and judged competing explanations as the argument developed.
Common Mistakes ⚠️
Mistake: Saying a multi-party system automatically produces coalition government
Why this is incorrect: Several parties can attract substantial support while FPTP still produces a parliamentary majority for one party.
How to improve: Separate:
multi-party electoral competition
from:
multi-party government.
Then explain how the electoral system connects the two.
Mistake: Treating the UK as either completely two-party or completely multi-party
Why this is incorrect: Different evidence can support different descriptions. Wider party competition exists alongside continued Labour and Conservative strength at Westminster.
How to improve: Judge the party system according to different criteria, such as votes, seats, government formation and regional politics.
Mistake: Assuming coalition government is always weak
Why this is incorrect: Coalitions involve compromise, but compromise does not automatically produce ineffective government.
How to improve: Compare possible costs, such as reduced clarity and modified manifestos, with possible benefits, such as broader representation.
Mistake: Explaining party success using only one factor
Why this is incorrect: Edexcel explicitly requires various factors affecting party success and failure.
How to improve:
Compare at least several explanations, for example:
leadership
policies
unity
campaign
governing record
media.
Then decide which is most significant.
Mistake: Assuming the media directly controls voters
Why this is incorrect: Voters are also influenced by policies, leaders, social characteristics, previous political events and established preferences.
How to improve: Use cautious analytical language such as:
"The media may shape or reinforce how voters interpret..."
rather than:
"The media makes people vote for..."
Mistake: Treating media bias as proof of media persuasion
Why this is incorrect: Biased coverage can favour one political position without necessarily changing anyone's vote.
How to improve:
Separate the questions:
Is the coverage biased?
Does that bias actually change political behaviour?
Mistake: Describing election examples without linking them to the factor being assessed
Why this is incorrect: Narrating an election demonstrates knowledge but does not automatically analyse party success.
How to improve: Use the structure:
evidence → effect on voter perception → consequence for party support → judgement
Exam-Style Questions ✍️
Question 1
Define a party system. (2 marks)
reveal mark scheme and indicative content
Answer:
A party system is the way or manner in which political parties within a political system are grouped and structured.
Question 2
Explain two possible implications of a multi-party system for government. (4 marks)
reveal mark scheme and indicative content
Indicative content:
Any two explained implications, such as:
coalition government, where more than one party participates in government and policies may have to be negotiated
minority government, where the governing party lacks a parliamentary majority and may need support from other parties
greater influence for smaller parties where their parliamentary support becomes important
increased policy compromise between parties
potentially less clear accountability because responsibility may be shared.
Award credit for explanation rather than identification alone.
Question 3
A general election produces the following hypothetical pattern:
Party | Share of votes |
Party A | 34% |
Party B | 31% |
Party C | 18% |
Party D | 10% |
Other parties | 7% |
Party A nevertheless wins enough constituencies under FPTP to form a single-party majority government.
Explain what this example demonstrates about the relationship between a multi-party system and government formation. (6 marks)
reveal mark scheme and indicative content
Indicative content:
A strong answer should explain that:
support is spread between several parties
this provides evidence of multi-party electoral competition
FPTP does not distribute seats proportionately according to national vote share
a multi-party electorate can therefore still produce single-party government
multi-party competition and coalition government are not the same thing
the electoral system mediates the relationship between voter choice and government formation.
Question 4
Analyse two factors, other than the media, that may affect whether a political party succeeds in a general election. (10 marks)
reveal mark scheme and indicative content
Indicative content:
Possible factors include:
leadership, because voters may judge the competence and credibility of the party through its leader
party unity, because division may damage confidence
policies and manifesto, because popular or unpopular proposals may affect support
campaign organisation, because effective communication can strengthen a party's message
governing competence, because an incumbent may be rewarded or punished for its record
voting patterns, because class, region, age or party attachment may favour different parties
electoral system, because support must be converted into seats
funding and organisation, because parties require resources to campaign.
Higher-level analysis should establish a clear causal chain rather than simply describing each factor.
Question 5
Read the following original source.
Some commentators argue that the media is the most important factor determining party success. Most voters encounter leaders, manifestos, campaign events and opinion polls through media coverage. Positive coverage can strengthen a party's message while hostile coverage can expose mistakes and divisions.Others argue that this exaggerates media power. Voters may already have strong political preferences, while economic conditions, government competence, party policies and leadership may be more important. The media may simply report strengths and weaknesses that already exist.
Using the source, analyse two reasons why it is difficult to determine whether the media causes party success. (10 marks)
reveal mark scheme and indicative content
Indicative content:
Students could analyse that:
the media reports other factors such as leadership and policies, making it difficult to separate media effect from the underlying political event
voters may select media reflecting preferences they already hold
long-term voting behaviour may already shape party choice
economic or political events may have affected party reputation before campaign coverage begins
media coverage may reinforce rather than change attitudes.
Stronger answers will explain why these factors make causation difficult to establish.
Question 6
Explain why party unity may contribute to electoral success while party division may contribute to failure. (10 marks)
reveal mark scheme and indicative content
Indicative content:
A strong response could develop:
unity allows a clear political message
a united party may appear more prepared to govern
internal conflict can shift attention away from policy
division may weaken confidence in leadership
media coverage may amplify visible disagreements
the 1997 Edexcel materials provide an example of Labour unity being contrasted with Conservative division.
Analysis should recognise that unity is one factor rather than an automatic guarantee of success.
Question 7
Evaluate the view that the development of a multi-party system has made coalition and minority governments increasingly important to UK politics. (30 marks)
reveal mark scheme and indicative content
Indicative content:
Arguments supporting the view could include:
voters support a wider range of parties
reduced domination by the two largest parties can make parliamentary majorities harder to secure
the Conservative-Liberal Democrat coalition demonstrates multi-party participation in Westminster government
minority or support arrangements can increase the influence of smaller parties
devolved politics demonstrates wider patterns of party competition and cooperation.
Alternative arguments could include:
FPTP can still convert multi-party voting into single-party majority government
Labour and Conservatives retain major organisational and electoral advantages
multi-party electoral competition does not automatically produce coalition
single-party governments retain advantages concerning accountability and manifesto implementation.
For AO3, strong responses should distinguish between changes in the electorate, Parliament and government formation.
A convincing judgement could argue that multi-party competition increases the possibility and political relevance of coalition and minority government, but the Westminster electoral system means it does not make these outcomes inevitable.
Question 8
Evaluate the view that the media is the most important factor determining whether a political party succeeds or fails. (30 marks)
reveal mark scheme and indicative content
Indicative content:
Arguments supporting the view could include:
media coverage shapes how voters encounter leaders and party policies
positive or hostile coverage can strengthen or weaken party image
media treatment can amplify campaign mistakes
parties themselves devote attention and resources to media presentation
opinion polls can affect campaign strategy and voter behaviour
Labour's improved media position in 1997 provides a source-supported example.
Alternative explanations could include:
party policies and manifestos
leadership
party unity or division
governing competence
economic and political context
campaign organisation
long-term voting patterns
class, age, region and other voter characteristics
electoral systems and party resources.
For AO2, students should compare factors rather than discuss them in isolated blocks.
For AO3, the strongest judgement may distinguish between the media as an independent cause and the media as an amplifier of other causes.
A possible conclusion is that media influence is significant because it shapes the presentation of leadership, policies and political events, but it rarely operates independently enough to be regarded as the sole or automatically dominant explanation for party success.
Question 9
Evaluate the view that party success depends more on the weaknesses of opponents than on a party's own strengths. (30 marks)
reveal mark scheme and indicative content
Indicative content:
Arguments supporting the view could include:
an unpopular government's record may damage it regardless of opposition performance
economic failure can undermine governing competency
party division can destroy voter confidence
scandals or appearing out of touch can benefit opponents
the 1997 materials allow an argument that Conservative weakness was central to Labour's victory.
Alternative arguments could include:
effective leadership can actively attract voters
policies and manifestos provide positive reasons to support a party
unity can strengthen confidence
effective campaign organisation can distinguish one party from another
positive media relations may improve a party's presentation
political rebranding can expand electoral appeal.
A strong response should avoid treating "opposition strength" and "government weakness" as entirely independent. The same political situation can involve both.
For AO3, students should identify the better explanation according to the evidence used and maintain this judgement throughout the essay.
