The committee at the top of British government - the Prime Minister and the senior ministers who run the departments. On paper it takes decisions collectively and speaks with one voice; in practice the balance of power between the Cabinet and the Prime Minister is the central question of the topic. Built around what the Cabinet is and does, the Great Offices of State, the cabinet-government against prime-ministerial-government debate, collective responsibility, and a worked 30-mark essay. Three short quizzes break the tour up.
The Cabinet is the committee at the centre of the UK executive: the Prime Minister and the senior ministers who head the main government departments. It meets weekly, takes the major collective decisions of government, and is bound to support them in public under the convention of collective responsibility. The most senior posts within it - the Great Offices of State - are the Prime Minister, the Chancellor of the Exchequer, the Foreign Secretary and the Home Secretary. But the Cabinet is a creation of convention, not statute, and its real power is contested. The classic exam question asks whether the UK still has cabinet government - decisions taken collectively by a team of senior figures - or whether it has shifted to prime-ministerial or even presidential government, where the PM dominates and the Cabinet is reduced to a rubber stamp. This walk-through opens with what the Cabinet is and does, takes you through the Great Offices in scrolly detail, runs the cabinet-versus-prime-ministerial debate, covers collective responsibility, and finishes with a worked 30-mark essay.
The committee at the top of British government - and why it is a creature of convention.
The Cabinet is the senior decision-making committee of the UK government. It is chaired by the Prime Minister and made up of the most senior ministers - usually around twenty - who between them run the main departments. Its job is to take the collective decisions of government: agreeing policy, settling disputes between departments, and presenting a single agreed line to Parliament and the public. Cabinet committees and sub-committees do much of the detailed work, coordinated through the Cabinet Office.
None of this is written into statute. The Cabinet is a creature of convention - the rules that govern it are unwritten understandings rather than law. The PM decides who sits in it, how often it meets, and how much real decision-making happens around the table rather than in smaller groups. That flexibility is exactly why the balance of power inside the Cabinet can shift so far from one premiership to the next, and why the central exam debate exists at all.
Scroll - each of the four senior posts lights with its department and what it controls.
Convention treats four posts as the Great Offices of State: the most senior portfolios beneath the Prime Minister. They are the Prime Minister, the Chancellor of the Exchequer, the Foreign Secretary and the Home Secretary. Knowing what each one controls is the AO1 foundation for any Cabinet essay - and the PM-versus-Chancellor relationship in particular is a recurring essay theme. Scroll through; the figure beside you holds the four offices with the one you are reading lit.
Prime Minister, Chancellor, Foreign Secretary, Home Secretary. Convention treats these as the senior portfolios under the PM - the top of the Cabinet hierarchy. Everything else in Cabinet sits beneath them.
The Prime Minister is the head of government and the chair of Cabinet. The powers are large: patronage (appointing and dismissing ministers, recommending peerages and honours), strategic direction (chairing Cabinet and setting the agenda), and the exercise of royal prerogative powers on the Crown's behalf - recommending dissolutions, signing treaties. The role is a creation of convention; Walpole (1721-42) is conventionally regarded as the first PM, and the modern dominant model was defined by Thatcher and given presidential overtones by Blair.
The Chancellor heads the Treasury and sets fiscal policy - tax and spending. The Chancellor delivers the Budget, controls every department's budget through the Spending Review, and is widely seen as the second-most-powerful figure in government and the most common stepping-stone to the premiership. The PM-Chancellor relationship is a classic essay theme: Brown against Blair (1997-2007), Lawson against Thatcher (resigned 1989), and Truss with Kwarteng in 2022, who fell together after the mini-budget.
The Foreign Secretary manages UK foreign policy, diplomatic relations and overseas development through the FCDO. The post is the one most often eclipsed by the Prime Minister - foreign policy is the area where PMs most often act as their own Foreign Secretary, from Blair on Iraq to Cameron on Libya. That tendency is itself evidence for the prime-ministerial-government side of the debate: when the PM takes the lead on the biggest foreign questions, the Cabinet's senior diplomat is sidelined.
The Home Secretary is responsible for policing in England and Wales, immigration and asylum, security and counter-terrorism. It is long regarded as the toughest brief in Cabinet, and in modern times almost no Home Secretary leaves the role with their reputation intact. The post matters for two papers: Home Secretary actions are the standard testing ground for rights-versus-security tensions on Paper 1, and Home Office clashes with the PM and the courts feed the executive-power debate on Paper 2.
The Great Offices are where the cabinet-versus-PM debate is fought out. A strong Chancellor can act as a rival power centre (Brown under Blair); a PM who runs foreign policy personally sidelines the Foreign Secretary; a Home Secretary who clashes with No 10 tests how far the PM really controls the Cabinet.
Hold the four posts in mind as you read the debate. The senior figures around the table are the people who can either check the PM or be dominated by them - and which it is depends on the politics of the moment.
Scroll - each model lights so you can weigh how far power has shifted to the centre.
The central debate is about the balance of power between the Cabinet and the Prime Minister. Three models compete: cabinet government (the PM as first among equals, decisions taken collectively), prime-ministerial government (the PM dominant, the Cabinet reduced), and the presidential thesis (the PM acting like a head of state, above party and Cabinet). Scroll through; the figure beside you shows the three models with the one you are reading lit.
Cabinet government, prime-ministerial government, presidential government. Each is a different answer to the same question - who really decides? The strongest essays test the PM's power against the limits the Cabinet still imposes.
On the cabinet government model the PM is first among equals - powerful, but one voice among the senior figures who take the major decisions together around the table. The Cabinet is a genuine collective body: it debates policy, settles disputes, and can constrain the PM. The evidence is the fall of dominant PMs at their colleagues' hands: Thatcher fell after a Cabinet revolt and leadership challenge in 1990, and Johnson was forced out in July 2022 when more than fifty ministers resigned in 48 hours. When the Cabinet withdraws its support, even the strongest PM is gone.
On the prime-ministerial model the PM dominates the executive. The tools are patronage (every minister owes their job to the PM), control of the agenda, and the Cabinet Office machinery that supports central coordination. Blair is the textbook case - the "sofa government" criticism held that he marginalised the full Cabinet, taking decisions in small informal groups and using the No 10 communications operation to set the line. On this view the Cabinet meets to ratify decisions already taken, not to make them.
The presidential thesis goes further: the PM behaves like a directly elected head of state, drawing authority from a personal public mandate and a direct relationship with the electorate through the media, rather than from the party or the Cabinet. Foley's "spatial leadership" idea describes a PM who stands apart from the government, presenting themselves to the public as the embodiment of it. Thatcher and Blair are the cases cited - leaders whose personal authority overshadowed their Cabinets.
The counter to the dominant-PM models is that prime-ministerial power is conditional, not fixed. It depends on a Commons majority, party support and personal authority - and when those fail, the Cabinet reasserts itself. Truss lasted 49 days in 2022 because the markets and then her own ministers turned against her. A strong Chancellor (Brown under Blair) can run a rival power centre. The PM proposes, but the Cabinet can still dispose when it chooses to.
Don't pick one model and defend it flat. The strongest answer is that the balance shifts with the strength of the PM: prime-ministerial or presidential when the PM is strong (Thatcher in her prime, Blair after 1997), cabinet government reasserting itself when the PM is weak (Thatcher's fall, Truss). Weigh the PM's tools against the limits, and judge which weighs more for the period the question is about.
What binds the Cabinet to one line, and why it has become conditional.
The Cabinet is held together by collective ministerial responsibility (CMR): the convention that every cabinet minister must publicly support government policy or resign. One voice, one team. It is the glue that lets a committee of strong-willed senior figures present a single agreed line to Parliament and the public - and its strength is a direct measure of how much real cabinet government there is.
But CMR has become conditional rather than steady. It has been formally suspended for big referendums - Wilson in 1975 for the EEC vote, Cameron in 2016 for the EU vote, when six cabinet ministers campaigned Leave from inside the Cabinet. It leaks routinely under weak PMs: May could not stop her Cabinet briefing against her, and Truss's ministers attacked her in public before she fell. And it reappears whenever a PM is strong enough to enforce it - Johnson reasserted it after his 2019 majority, and Javid's resignation as Chancellor in February 2020 was the price of that reassertion. Crucially, when the Cabinet withdraws its collective support, the convention becomes a weapon: the mass resignations of July 2022 removed Johnson within two days.

Cabinet questions to practise.
Approach: Theme 1 - the PM's tools: patronage, agenda control and the Cabinet Office point to dominance (Blair's sofa government). Theme 2 - the Cabinet's limits: a strong Chancellor (Brown) and the senior figures can act as rival power centres. Theme 3 - the conditional case: the PM is dominant only while authority holds (Thatcher's fall, Truss's 49 days, Johnson removed July 2022). Judgement: the balance shifts with the strength of the PM - prime-ministerial when strong, cabinet government reasserting when weak.
Approach: Theme 1 - patronage and the centre: the PM appoints the Cabinet and runs the agenda (Blair; Foley's spatial leadership). Theme 2 - the Cabinet as a check: collective responsibility can become a weapon (Johnson removed July 2022; Thatcher 1990). Theme 3 - power is conditional: it depends on majority, party and authority (Truss). Judgement: powerful but not unchecked - the limits are real when the politics turn.
Approach: Theme 1 - the case it has weakened: formal suspensions (Wilson 1975, Cameron 2016) and routine leaking under weak PMs (May, Truss). Theme 2 - the case it still binds: strong PMs enforce it (Johnson post-2019; Javid resigned February 2020). Theme 3 - the convention as a weapon: the July 2022 mass resignations removed a PM. Judgement: conditional, not dead - its force tracks the strength of the PM. See the ministerial responsibility notes for the full case library.
Judgement. The UK does not have settled prime-ministerial government. The PM has the tools to dominate and uses them when strong, which is why Blair could marginalise his Cabinet and Thatcher and Blair could be read as presidential. But the dominance is conditional, and the Cabinet retains the ultimate check: it can withdraw its support and remove the PM, as it did to Thatcher in 1990 and Johnson in July 2022, and it reasserts itself the moment a PM's authority fails, as Truss found. The most accurate view is that power oscillates between the PM and the Cabinet with the strength of the premiership - prime-ministerial in strong hands, cabinet government when those hands weaken.
