Estimated study time:Â 50 minutes
The Prime Minister and Cabinet A-Level Politics revision focuses on one of the most important debates within UK government: where does power really lie within the Executive? You need to understand the factors governing the Prime Minister's selection of ministers, the changing relationship between the Prime Minister and Cabinet, and the circumstances that strengthen or weaken each side. This builds directly on ministerial conventions [Ministerial responsibility] and prepares you to study detailed examples of prime-ministerial power before 1997 [Prime-ministerial power: pre-1997 case study] and after 1997 [Prime-ministerial power: post-1997 case study].
Learning Objectives 🎯
By the end of this revision page, you should be able to:
Explain the Prime Minister's power to appoint and dismiss ministers.
Explain the political factors that limit the Prime Minister's freedom when selecting a Cabinet.
Analyse how patronage, party unity, electoral strength and powerful ministers affect Prime Minister-Cabinet relations.
Explain how Cabinet procedures and collective ministerial responsibility may strengthen the Prime Minister.
Analyse how Cabinet resignations, opposition from senior ministers and political weakness can constrain the Prime Minister.
Evaluate whether power lies mainly with the Prime Minister or remains shared with Cabinet.
The specification requires students to understand both the factors governing ministerial selection and the changing balance of power between the Prime Minister and Cabinet.

The Prime Minister and Cabinet A-Level Politics revision overview
The Cabinet consists of the Prime Minister and senior ministers, most of whom lead a government department.
The relationship between the Prime Minister and Cabinet creates a fundamental tension within UK government.
On one side, the Prime Minister possesses major advantages:
selecting and dismissing ministers
determining Cabinet membership
chairing Cabinet
setting its agenda
using Cabinet committees
relying on collective ministerial responsibility
working through smaller groups of advisers or senior ministers
On the other side, a Prime Minister cannot normally govern effectively without ministers who:
command support within the governing party
run major government departments
deliver government policy
support the Prime Minister politically
This means that the relationship is not fixed.
Prime-ministerial strength and Cabinet strength change according to political circumstances.
This is the central idea to understand for this lesson.
The Prime Minister's selection of ministers
The Prime Minister has substantial patronage because they can appoint ministers and determine who serves in Cabinet.
This appears to give the Prime Minister considerable power.
A Prime Minister may seek to appoint ministers who:
are loyal
share their ideological preferences
will support their political priorities
The 2023 Edexcel mark scheme identifies the appointment and removal of ministers as an important means through which Prime Ministers may attempt to shape Cabinet in their own image.
However, selection is not completely free.
Patronage
The Prime Minister's ability to appoint, promote, demote and dismiss ministers can be described as a power of patronage.
Patronage can strengthen the Prime Minister because ambitious politicians may have an incentive to remain loyal if:
promotion is possible
prestigious Cabinet positions are available
disloyalty may result in dismissal or demotion
A powerful Prime Minister may therefore use appointments to construct a Cabinet containing ministers who broadly support their political direction.
The 2023 mark scheme argues that this is particularly effective when a Prime Minister is popular and has secured a convincing electoral victory.
Loyalty and ideological agreement
Prime Ministers may prefer ministers who are:
politically loyal
supportive of their leadership
ideologically compatible
This can make Cabinet easier to manage because serious disagreements may be less likely.
The 2023 source presented the argument that Prime Ministers can appoint politicians who are loyal and share their ideological preferences while removing opponents.
This suggests a possible chain of influence:
appointment power → more supportive Cabinet → easier control of Cabinet → stronger Prime Minister
However, the Prime Minister's freedom remains constrained by other political factors.
The need to represent different wings of the governing party
Prime Ministers cannot necessarily fill Cabinet only with their closest supporters.
Different groups within the governing party may need representation.
The 2019 Edexcel mark scheme identifies the need to balance:
different wings of the party
different positions on major political issues
regional considerations
gender
It also identifies Theresa May's need to maintain representation from both supporters and opponents of Brexit as an example of party divisions limiting appointment freedom.
The key point is analytical:
A Prime Minister's formal power to appoint ministers may be considerable, but political circumstances can restrict who can realistically be appointed.
Powerful senior figures, the "big beasts"
A Prime Minister may also have to appoint important senior politicians who possess their own support and political authority.
Edexcel mark schemes refer to these figures as "big beasts".
Leaving a powerful rival outside Cabinet may be risky because that politician could criticise the government from the backbenches.
Bringing them into Cabinet can:
incorporate them into government
bind them through collective responsibility
reduce the freedom with which they can publicly attack policy
However, appointing powerful figures creates another problem.
Once inside Cabinet, these ministers may have sufficient political influence to constrain the Prime Minister.
This creates a useful evaluation:
Including powerful rivals may strengthen the Prime Minister by containing them, but it may also strengthen Cabinet by placing independently powerful politicians within government.
Party unity
The degree of unity within the governing party has a major effect on ministerial selection.
When a party is united and the Prime Minister is dominant, the Prime Minister may enjoy greater freedom to choose supportive ministers.
When a party is divided, the Prime Minister may need to appoint ministers representing competing factions.
This can make Cabinet:
less ideologically uniform
more difficult to control
more important as a place where political compromises must be reached
The 2019 and 2023 mark schemes both identify party division as an important limitation on prime-ministerial patronage.
Coalition government
Coalition government creates an especially strong limitation on prime-ministerial selection.
The 2020 mark scheme uses the 2010 Coalition as evidence that Cabinet may become more important because it contains ministers from another political party.
A Prime Minister governing through a coalition cannot treat ministerial selection in the same way as the leader of a secure single-party majority government.
The Prime Minister must take account of:
the coalition partner
the distribution of Cabinet positions
the political agreements underlying the coalition
This reduces freedom of patronage.
Ministers may resist demotion or dismissal
The Prime Minister's appointment powers also have practical limits because senior ministers may resist attempts to move or remove them.
The 2023 mark scheme gives examples of ministers:
refusing demotion
challenging the Prime Minister to dismiss them
accepting positions only on particular conditions
Dismissed ministers can also become political opponents from the backbenches.
This means patronage can backfire.
A useful judgement is:
Patronage is potentially one of the Prime Minister's strongest powers over Cabinet, but its effectiveness depends on the political strength of the Prime Minister and the political strength of the minister concerned.
Summary: factors governing ministerial selection
Factor | How it may affect the Prime Minister's choice |
Loyalty | Encourages appointment of politicians likely to support the Prime Minister. |
Ideological preference | Allows the Prime Minister to try to shape Cabinet around their political direction. |
Party factions | May require rival wings of the party to be represented. |
Powerful senior figures | Important politicians may be difficult to exclude from Cabinet. |
Coalition government | Reduces freedom because positions must accommodate another governing party. |
Representation and balance | Regional, gender and other political considerations may influence appointments. |
Strength of individual ministers | Powerful politicians may resist dismissal or demotion. |
The relationship between Prime Minister and Cabinet
The relationship between the Prime Minister and Cabinet is best understood as a variable balance of power.
The Prime Minister is always important, but the extent of prime-ministerial dominance changes.
The 2020 examiner report praised answers that focused directly on whether power had shifted towards Cabinet or remained mainly with the Prime Minister, rather than simply describing different governments.
A strong revision strategy is therefore to organise evidence by factors, not simply by Prime Minister.
Factor 1: Control of the Cabinet agenda
The Prime Minister chairs Cabinet and can exert influence over:
what Cabinet discusses
when matters are considered
the conduct of Cabinet discussions
The 2019 mark scheme identifies the Prime Minister's ability to decide what is discussed in Cabinet as an important source of power.
The 2023 mark scheme similarly identifies the ability to:
set the Cabinet agenda
chair Cabinet
influence the recording of Cabinet decisions
as ways a dominant Prime Minister may limit the opportunity for Cabinet to challenge decisions.
This gives the Prime Minister an important procedural advantage.
Factor 2: Decisions made outside full Cabinet
Prime Ministers may reduce the influence of full Cabinet by making important decisions elsewhere.
Edexcel mark schemes identify several mechanisms:
Cabinet committees
bilateral meetings between the Prime Minister and individual ministers
inner Cabinets
smaller groups of trusted allies and advisers
The 2023 mark scheme gives examples of different Prime Ministers using these arrangements to exercise greater control over decision making.
The important point is not simply that these mechanisms exist.
The analytical argument is:
If important policy has already been agreed before full Cabinet meets, Cabinet risks becoming a body that approves decisions rather than genuinely determining them.
This is the argument behind describing Cabinet as a rubber stamp.
Cabinet as a "rubber stamp"
A Cabinet becomes a rubber stamp where it formally approves decisions that have effectively been taken elsewhere.
The 2023 Edexcel source explicitly presented the argument that Cabinet may simply agree decisions already made by important ministers or smaller groups.
However, the same source stressed that this can depend on how the Prime Minister runs Cabinet.
Therefore:
Cabinet weakness is not automatic.
Different Prime Ministers can organise decision making differently.
Factor 3: Collective ministerial responsibility
Collective ministerial responsibility requires ministers to support Cabinet decisions or leave the Executive.
This convention can strengthen the Prime Minister because once a policy is agreed, ministers are expected to defend it publicly.
A Prime Minister may therefore use collective responsibility to:
maintain public unity
prevent Cabinet ministers openly attacking policy
discipline dissenting ministers
The 2023 mark scheme identifies collective responsibility as an important mechanism through which a Prime Minister can keep Cabinet in line.
This directly links to your study of collective responsibility [Ministerial responsibility].
However, collective responsibility does not eliminate Cabinet power.
A minister who strongly disagrees may resign, and a major resignation can seriously damage the Prime Minister.
Factor 4: Cabinet resignations
Senior ministerial resignations can shift the balance of power towards Cabinet.
A resignation may suggest:
government division
failure of prime-ministerial leadership
a loss of confidence in the Prime Minister
the existence of serious policy disagreement
One resignation may also encourage others.
The 2023 mark scheme states that resignations by senior ministers can severely limit the Prime Minister's power and may contribute to the removal of a Prime Minister.
This produces an important paradox.
Collective responsibility may strengthen a Prime Minister by demanding loyalty, but when a minister chooses resignation rather than loyalty, the convention can expose the Prime Minister's weakness.
Factor 5: Powerful Cabinet ministers
Cabinet power is greater when it contains politicians with substantial independent political authority.
These ministers may possess:
strong support within the governing party
responsibility for an important government department
a significant public profile
the ability to influence other ministers
The 2023 source states that powerful ministers may be able to block or reverse Prime Ministerial policies.
The Prime Minister therefore cannot always treat Cabinet ministers as politically dependent subordinates.
The importance of government departments
Cabinet ministers usually head major government departments.
Government policy must ultimately be delivered through those departments.
The 2023 mark scheme therefore argues that Prime Ministers remain reliant on Cabinet ministers because ministers are responsible for implementing government policy.
This creates an important practical limit on Prime Ministerial dominance:
A Prime Minister may dominate political presentation and even much policy formation, but government still depends on senior ministers to make policy work through their departments.
This connects back to the organisation and role of government departments [Structure, role and powers of the Executive].
Factor 6: Size of the parliamentary majority
The size of the government's majority in the House of Commons can have a major effect on Prime Minister-Cabinet relations.
A Prime Minister with a large majority may be stronger because:
government legislation is more secure
backbench rebellions are less threatening
the Prime Minister may claim a stronger electoral mandate
Cabinet ministers may be less able to exploit parliamentary weakness
The 2019 mark scheme states that a Prime Minister with a large Commons majority faces fewer constraints on pursuing the government's legislative programme.
By contrast, a small or non-existent majority can increase Cabinet influence.
Minority government
A Prime Minister without a secure Commons majority must be more cautious.
The 2020 mark scheme uses Theresa May's loss of her Commons majority in 2017 as evidence of a weakened Prime Minister and a more prominent Cabinet.
The relationship is:
weaker parliamentary position → weaker Prime Minister → greater need for Cabinet support
This also connects to the wider relationship between the Executive and legislature [The Executive and Parliament].
Coalition government and Cabinet power
The 2010 Coalition also strengthened the argument for Cabinet government.
David Cameron governed alongside Liberal Democrat ministers, which meant policy could not simply be shaped as though the government were a unified Conservative administration.
The 2020 mark scheme treats coalition as evidence that Cabinet gained importance.
However, coalition does not necessarily mean that full Cabinet controls government.
The same mark scheme notes that Cameron's use of the coalition "quad"Â enabled key decisions to be taken outside full Cabinet.
This gives you an excellent evaluation:
Coalition may weaken unilateral Prime Ministerial power while simultaneously concentrating decision making in a smaller group rather than strengthening full Cabinet.
Factor 7: Party unity and division
Party unity can be even more important than the formal powers of the Prime Minister.
A Prime Minister leading a united governing party is generally better placed to dominate Cabinet.
A Prime Minister leading a divided party may need to:
include rivals in Cabinet
compromise over policy
avoid dismissing powerful ministers
manage competing factions carefully
The 2020 mark scheme identifies Conservative divisions over Brexit as a major reason Cabinet became more prominent during Theresa May's premiership.
The 2023 mark scheme similarly argues that an unpopular Prime Minister leading a divided party will find patronage less effective.
Factor 8: Prime-ministerial popularity
Popularity can strengthen the Prime Minister's position in relation to Cabinet.
A Prime Minister who is:
popular with the public
seen as an electoral asset
associated with electoral success
may be more difficult for Cabinet colleagues to challenge.
The 2019 mark scheme identifies an electorally successful Prime Minister as facing fewer limits because colleagues have less incentive to remove a leader who appears likely to help them win elections.
The reverse also applies.
An unpopular Prime Minister may become increasingly dependent upon Cabinet support.
Factor 9: Electoral mandate
A large electoral victory may allow a Prime Minister to claim a strong mandate.
This can increase authority within:
Cabinet
the governing party
Parliament
The 2020 examiner report specifically identifies the size of the government's majority and the importance of mandate as useful factors when analysing the balance between Prime Minister and Cabinet.
This creates an important link between UK Government and the study of elections.
Factor 10: Leaks and internal dissent
Cabinet discussions are expected to remain confidential.
Leaks to the media can weaken the Prime Minister by making internal divisions public.
The 2023 source and mark scheme identify leaks as a means through which ministers may damage prime-ministerial authority.Leaks can be politically important because they suggest that:
Cabinet is divided
ministers are unwilling to maintain confidentiality
the Prime Minister cannot completely control senior colleagues
They can therefore shift the perceived balance of power away from the Prime Minister.
Factor 11: Ability of Cabinet to remove a Prime Minister
Perhaps the most important limitation on prime-ministerial dominance is that a Prime Minister who loses the support of Cabinet and their governing party may not remain in office.
The 2019 mark scheme uses Margaret Thatcher as an example of a Prime Minister whose authority collapsed after Cabinet support was lost.
The 2023 mark scheme also identifies loss of Cabinet confidence as a factor that can weaken a Prime Minister's ability to govern and contribute to their removal.
This creates one of the strongest arguments against unlimited prime-ministerial power:
The Prime Minister appoints Cabinet ministers, but ultimately a Prime Minister who loses the political confidence of Cabinet may be unable to survive.
Comparing factors that shift the balance of power
Factor | Tends to strengthen Prime Minister | Tends to strengthen Cabinet |
Patronage | PM appoints loyal or ideologically supportive ministers. | Powerful ministers may resist dismissal or become dangerous rivals. |
Party unity | A united party makes Cabinet easier to control. | Party divisions require compromise and factional balance. |
Commons majority | Large majority strengthens PM authority. | Small majority or minority government makes Cabinet support more important. |
Electoral popularity | Successful PM can claim authority and mandate. | Unpopular PM becomes more vulnerable to Cabinet pressure. |
Collective responsibility | Limits public criticism by ministers. | Resignation rather than conformity can expose government division. |
Cabinet procedures | PM controls agenda and can use smaller decision-making groups. | Strong Cabinet ministers may demand genuine collective discussion. |
Policy delivery | PM can establish government direction. | Departmental ministers are needed to implement policy. |
Resignations and leaks | Loyal Cabinet protects PM authority. | Resignations and leaks can seriously weaken the PM. |
Is the Prime Minister more powerful than Cabinet?
There are several strong arguments that the Prime Minister normally possesses the advantage.
Prime Ministerial argument 1: patronage
The Prime Minister determines Cabinet membership.
This can enable them to:
reward loyalty
promote supporters
dismiss opponents
influence Cabinet's ideological composition
This gives the Prime Minister an institutional advantage over ministers.
Prime Ministerial argument 2: control of Cabinet organisation
The Prime Minister:
chairs Cabinet
sets the agenda
can structure Cabinet committees
may use smaller groups or bilateral discussions
This allows a powerful Prime Minister to control how decisions are made.
Prime Ministerial argument 3: collective responsibility
Once decisions are made, Cabinet ministers are expected to support them publicly.
This can limit the ability of ministers to challenge the Prime Minister while remaining in government.
Prime Ministerial argument 4: electoral authority
An electorally popular Prime Minister with a large Commons majority may have considerable political authority over colleagues.
Cabinet ministers may be reluctant to challenge a leader who is viewed as responsible for electoral success.
Prime Ministerial argument 5: presidential tendencies
The specification includes presidential government as key terminology for this topic.
It defines presidential government as:
an Executive dominated by one individual, which may describe a strong, dominant Prime Minister.
A strong Prime Minister may therefore appear increasingly separate from collective Cabinet government.
However, this does not mean the UK Prime Minister is literally a president.
The term describes the degree of dominance within the Executive.
Arguments that Cabinet remains powerful
Cabinet argument 1: ministers possess their own political authority
Senior Cabinet ministers may have significant influence within the governing party.
The Prime Minister may therefore have to negotiate with rather than simply command them.
Cabinet argument 2: Cabinet ministers control government departments
Government cannot be implemented by the Prime Minister alone.
Cabinet ministers head departments responsible for delivering policy, creating continued dependence on senior colleagues.
Cabinet argument 3: patronage has limits
The Prime Minister may be unable to exclude important factions or major political figures.
Dismissal may also create a powerful opponent outside government.
Cabinet argument 4: resignations damage the Prime Minister
A significant Cabinet resignation can turn disagreement into a public crisis.
Several resignations can create the impression that the Prime Minister has lost control.
Cabinet argument 5: Prime Ministers depend on Cabinet confidence
A Prime Minister who loses Cabinet support may become unable to govern effectively.
Cabinet is therefore not simply a group that exists at the Prime Minister's pleasure in any meaningful political sense.
Formal powers versus political circumstances
One of the most important distinctions for evaluation is between:
formal advantages and political circumstances.
The Prime Minister possesses several continuing advantages:
appointment and dismissal
chairing Cabinet
setting its agenda
organising decision making
But whether these powers create dominance depends on factors such as:
majority size
party unity
electoral popularity
the presence of powerful ministers
political events
resignations and dissent
This is why the balance between Prime Minister and Cabinet changes without the formal structure of government necessarily changing.
The balance of power is conditional
A sophisticated judgement should avoid statements such as:
"The Prime Minister is always dominant."
or:
"Cabinet is always the most powerful."
Instead, think conditionally.
A Prime Minister is more likely to dominate when:
the government has a large Commons majority
the governing party is united
the Prime Minister is electorally popular
Cabinet contains loyal supporters
there are few powerful rivals
collective responsibility is maintained
important decisions can be controlled through Cabinet procedures or smaller groups
Cabinet is more likely to become powerful when:
the government has a small majority or no majority
the governing party is divided
the Prime Minister is unpopular
Cabinet contains powerful independent figures
ministers resist demotion or dismissal
senior ministers resign
Cabinet discussions are leaked
the Prime Minister depends on Cabinet to maintain political support
Example: Thatcher
Edexcel mark schemes use Margaret Thatcher to demonstrate both sides of the debate.
A strong Prime Minister may use patronage and electoral success to build greater control.
Yet Thatcher's departure also illustrates the limits of prime-ministerial authority when Cabinet support collapses.
This makes Thatcher particularly useful because the example demonstrates that Prime Ministerial power can change during a premiership.
You will explore such changes in greater depth when studying a pre-1997 Prime Minister's control over policy and events [Prime-ministerial power: pre-1997 case study].
Example: Theresa May
Theresa May is also used repeatedly in Edexcel material to illustrate the conditional nature of prime-ministerial power.
The mark schemes identify:
the need to balance different Conservative factions
the loss of the Commons majority in 2017
divisions over Brexit
greater Cabinet influence as her authority weakened
Her premiership demonstrates the relationship between:
party division + parliamentary weakness + reduced patronage → stronger Cabinet constraints
Example: Cameron and coalition
The 2010 to 2015 Coalition demonstrates another complexity.
Coalition government increased the importance of compromise and placed limits on the Prime Minister's freedom.
However, the use of the coalition quad also shows how important decisions could be moved away from full Cabinet into a much smaller group.
This means an apparent decline in single-person prime-ministerial power does not necessarily equal a straightforward rise in full Cabinet government.
Example: Boris Johnson
The 2020 and 2023 mark schemes use Boris Johnson to demonstrate how electoral strength and loyal appointments may strengthen Prime Ministerial control.
The 2020 mark scheme identifies the creation of a Cabinet of loyalists as evidence that patronage can help a Prime Minister dominate Cabinet.
However, later Cabinet resignations are also used by Edexcel as evidence of how ministerial opposition can weaken and ultimately threaten a Prime Minister.
Again, the key lesson is change over time.
Power can change during the same premiership
This is one of the most important ideas for high-level evaluation.
Do not simply classify a Prime Minister as either "strong" or "weak".
Their position can change because:
election results change
popularity rises or falls
party divisions develop
Cabinet membership changes
political events damage authority
ministers become more willing to resist
The 2020 examiner report praised responses that recognised changing relationships rather than treating the period as static.
A useful evaluative model
When assessing the balance of power, ask four questions:
How much political choice does the Prime Minister have over Cabinet membership?
Can the Prime Minister control how decisions are made?
Does the Prime Minister retain the support needed to implement those decisions?
What would happen if important Cabinet ministers resisted?
This moves an answer from description towards analysis.
Overall assessment of the balance of power
The Prime Minister normally begins with substantial advantages over Cabinet.
They:
appoint ministers
chair Cabinet
influence its agenda
organise decision-making structures
benefit from collective ministerial responsibility
However, these advantages are not equivalent to unlimited power.
The Prime Minister depends on:
Cabinet ministers to run departments
Cabinet support for political authority
party unity
parliamentary strength
continued electoral credibility
The most defensible overall conclusion is therefore:
The Prime Minister normally has greater institutional advantages than any individual Cabinet minister, but the balance of power is conditional rather than fixed. Prime-ministerial dominance is greatest when electoral strength, party unity and patronage reinforce one another. When those conditions disappear, Cabinet can become a major constraint and may even contribute to the Prime Minister's removal.

Hints from the Examiner Reports đź’ˇ
Examiner hint:Â Focus on the balance of power, not simply on describing what different Prime Ministers did. The 2020 examiner report said that framing the debate around whether power had shifted towards Cabinet or remained with the Prime Minister was essential for moving beyond AO1 description.
Examiner hint: Organising an essay by factors can be highly effective. The 2020 report praised responses that analysed themes affecting the relationship, rather than simply narrating events chronologically.
Examiner hint:Â Use election results analytically. The size of the government's Commons majority can help explain why one Prime Minister is better able to dominate Cabinet than another. The examiner report specifically highlighted successful links between the size of the majority, mandate and prime-ministerial power.
Examiner hint:Â Use comparison over time. Stronger responses compared different periods and Prime Ministers to establish whether the balance of power had genuinely changed. Historical examples should support analysis rather than become isolated mini-biographies.
Examiner hint:Â Contemporary evidence should be selected to prove an argument. Examiners praised answers where examples were clearly chosen to underpin the analysis rather than simply demonstrate knowledge.
Examiner hint:Â Avoid generic essays about prime-ministerial power. The 2025 report warned that weaker responses sometimes wrote chronological accounts of different Prime Ministers without analysing the factors that enhanced or inhibited their power. The question asked must determine the structure of the answer.
Examiner hint:Â Pay close attention to qualifying words such as "mainly", "now", "too"Â or "since". These words determine the judgement you need to make rather than merely describe the existence of Prime Ministerial powers.
Common Mistakes ⚠️
Mistake: Saying the Prime Minister can appoint absolutely anyone they want
Why this is incorrect: Although the Prime Minister has substantial appointment powers, political constraints may require representation of:
different party factions
powerful senior politicians
coalition partners
different political positions
How to improve: Distinguish between formal appointment power and practical political freedom.
Mistake: Assuming patronage always strengthens the Prime Minister
Why this is incorrect: Dismissed or demoted ministers may resist, resign or become political opponents.
How to improve: Evaluate patronage both ways:
Patronage can promote loyalty, but using it against a powerful minister can create a dangerous rival.
Mistake: Treating Cabinet as automatically weak because the Prime Minister chairs it
Why this is incorrect: Cabinet contains senior ministers who run government departments and may possess significant independent political influence.
How to improve: Ask whether the Prime Minister has the political strength to turn procedural advantages into actual dominance.
Mistake: Assuming a coalition automatically produces Cabinet government
Why this is incorrect: Coalition can make collective negotiation more important, but decisions may still be concentrated within smaller groups rather than full Cabinet.
How to improve: Use the 2010 to 2015 experience analytically. Coalition constrained Cameron, but the use of the coalition quad also bypassed full Cabinet.
Mistake: Judging Prime Ministerial power using only formal powers
Why this is incorrect: The same formal powers can produce very different outcomes under different Prime Ministers.
How to improve:
Consider political factors including:
majority size
party unity
popularity
Cabinet composition
resignations
powerful ministers
Mistake: Assuming a large majority automatically makes the Prime Minister dominant
Why this is incorrect: A large majority can strengthen the Prime Minister, but Cabinet relationships also depend upon party unity, ministerial support and political authority.
How to improve: Treat majority size as one factor, not a complete explanation.
Mistake: Writing one paragraph on each Prime Minister
Why this is incorrect: This often becomes chronological description rather than analysis of the relationship between Prime Minister and Cabinet.
How to improve:
Organise paragraphs around factors such as:
patronage
party unity
electoral strength
Cabinet resignations
decision-making structures
Then compare examples within each factor.
Mistake: Assuming Prime Ministerial power remains constant
Why this is incorrect: The balance of power can change dramatically during one premiership.
How to improve:
Look for turning points such as:
election results
loss of popularity
party divisions
Cabinet resignations
changes in parliamentary strength

Source
Prime Ministers possess important advantages over Cabinet. They appoint and dismiss ministers, chair Cabinet and influence what it discusses. A politically strong Prime Minister can appoint loyal supporters, use collective ministerial responsibility to maintain unity and move important decisions into Cabinet committees or smaller meetings. If the Prime Minister is popular, leads a united party and commands a large parliamentary majority, Cabinet ministers may have little incentive or opportunity to challenge their leadership.
However, the Prime Minister cannot always choose ministers freely. Powerful figures and rival sections of the governing party may need to be represented. Cabinet ministers run major government departments and are necessary for the delivery of policy. An unpopular Prime Minister leading a divided party may become increasingly dependent upon senior ministers. Cabinet resignations, leaks and opposition from powerful ministers can weaken the Prime Minister, while dismissing an opponent may simply create a powerful critic outside government.
Using the source, evaluate the view that power within the Executive lies mainly with the Prime Minister rather than Cabinet.
In your response you must:
compare and contrast the different opinions in the source
examine and debate these views in a balanced way
analyse and evaluate only the information presented in the source

Answers and Mark Scheme
Question 1
Award up to 2 marks.
A strong answer should explain that Cabinet consists of:
the Prime Minister
senior ministers
most of whom lead a particular government department
Question 2
Award up to 2 marks for each developed factor, to a maximum of 4 marks.
Possible answers include:
The Prime Minister may have to represent different wings or factions of the governing party.
Powerful senior political figures may be difficult to exclude.
A coalition Prime Minister may have to appoint ministers from the coalition partner.
Political balance, including regional and gender considerations, may affect appointments.
Powerful ministers may be able to resist attempts to demote or remove them.
Question 3
Award up to 6 marks.
Indicative content:
Patronage gives the Prime Minister the ability to appoint ministers.
The Prime Minister can promote politicians who are loyal.
Ministers sharing the Prime Minister's ideological preferences may also be appointed.
Opponents may be removed or demoted.
Ambitious politicians may have an incentive to remain loyal because future advancement depends on the Prime Minister.
This can make Cabinet easier for a politically strong Prime Minister to control.
Higher marks require explanation of how appointment powers affect the balance of power.
Question 4
Award up to 6 marks.
Indicative content:
They may strengthen the Prime Minister because:
bringing rivals into Cabinet binds them to collective responsibility
it may be safer to include powerful politicians within government than leave them as critics outside it
They may weaken the Prime Minister because:
powerful ministers possess their own political support
they may resist prime-ministerial policies
they may challenge demotion or dismissal
resignation by a senior figure may seriously damage the Prime Minister
Higher marks require both sides to be explained.
Question 5
Award up to 8 marks.
Indicative content:
A large Commons majority strengthens the government's parliamentary position.
The Prime Minister may be able to claim a strong electoral mandate.
Party unity reduces the need to balance competing factions within Cabinet.
Loyal Cabinet appointments strengthen patronage.
Collective responsibility may further restrict public disagreement.
Cabinet ministers have fewer incentives to challenge an electorally successful leader.
The balance is therefore likely to shift towards Prime Ministerial dominance.
However, ministers remain necessary for departmental policy delivery.
Question 6
Award up to 8 marks.
Indicative content:
A divided party reduces the Prime Minister's freedom to appoint only loyalists.
Competing factions may require representation in Cabinet.
Lack of a secure Commons majority weakens the Prime Minister's political authority.
Senior ministers may become more able to influence policy.
Public disagreement undermines the appearance of Cabinet unity.
A threatened resignation may place pressure on the Prime Minister to compromise.
Losing a senior minister could expose further divisions.
Cabinet therefore becomes more important as the Prime Minister's wider political authority declines.
Question 7
A strong answer should consider both views.
Arguments supporting the view
The Prime Minister appoints ministers.
Ministers may depend on the Prime Minister for promotion.
Opponents can be dismissed.
Loyal appointments may make Cabinet easier to dominate.
The Prime Minister chairs Cabinet and controls important elements of its organisation.
Arguments challenging the view
Important factions may need Cabinet representation.
Powerful ministers may be difficult to remove.
Ministers can refuse demotions or resign.
Dismissed ministers may become damaging political opponents.
Cabinet ministers deliver policy through government departments.
Loss of Cabinet support can undermine the Prime Minister's ability to remain in office.
Judgement
The power of appointment provides an important Prime Ministerial advantage, but it does not mean Cabinet can never constrain the Prime Minister. Patronage itself becomes weaker when the Prime Minister is politically vulnerable or when Cabinet contains powerful figures.
Higher-level responses should judge the conditions under which patronage becomes more or less effective.

Arguments supporting Prime Ministerial dominance
Students may develop source points including:
the Prime Minister appoints and dismisses ministers
the Prime Minister chairs Cabinet
the Prime Minister influences the Cabinet agenda
loyal supporters can be promoted
collective ministerial responsibility can maintain discipline
important decisions may be shifted to committees or smaller meetings
popularity can strengthen prime-ministerial authority
a united party strengthens the Prime Minister
a large Commons majority strengthens the Prime Minister's political position
Arguments supporting Cabinet power
Students may develop source points including:
ministerial selection is politically constrained
party factions may need representation
powerful politicians may have to be appointed
Cabinet ministers run government departments
ministers are needed to implement policy
an unpopular Prime Minister becomes more dependent on Cabinet
party division increases Cabinet influence
resignations can damage the Prime Minister
leaks reveal internal disagreement
dismissing powerful ministers can create opponents
Comparative analysis
Strong responses should pair competing arguments rather than discuss each side separately.
For example:
Patronage versus political constraints
The Prime Minister formally selects ministers, but this power may be limited where powerful factions or senior figures must be represented.
Collective responsibility versus resignation
Collective responsibility may force ministers to support government policy, but resignation allows a powerful minister to reject that discipline and potentially weaken the Prime Minister.
Cabinet control versus policy delivery
The Prime Minister may control Cabinet procedures and move decisions into smaller forums, but Cabinet ministers remain responsible for the departments through which government policy is implemented.
Electoral authority versus political weakness
A large majority and popularity may allow Prime Ministerial dominance, while a small majority, party division or falling popularity can make the Prime Minister increasingly dependent on Cabinet.
Evaluation
A strong overall judgement might argue that power normally lies more heavily with the Prime Minister because the Prime Minister possesses important structural advantages over individual Cabinet ministers, particularly patronage and control over Cabinet organisation.
However, this dominance is conditional.
Where a Prime Minister:
loses electoral authority
leads a divided party
lacks a secure parliamentary majority
faces resistance from powerful ministers
Cabinet can become substantially more influential.
The strongest conclusion should therefore avoid presenting the relationship as permanently settled:
The Prime Minister usually has the advantage, but the balance of power depends more on political circumstances than on formal powers alone.
For the highest levels:
remain focused on the exact balance between Prime Minister and Cabinet
compare competing arguments directly
analyse factors rather than narrating successive premierships
explain why evidence strengthens one side of the debate
consider change over time
develop substantiated judgements throughout
ensure the conclusion follows logically from the argument
