The Core Executive

The UK executive is the branch of government that proposes policy, runs departments and directs the state. In AQA Politics, the most useful starting point is not just "the Prime Minister" or "the Cabinet", but the core executive.

The core executive is the network of people and institutions at the centre of UK government that coordinate policy and resolve disputes. It includes the Prime Minister, Cabinet, Cabinet committees, No. 10, the Cabinet Office, the Treasury, departments, senior civil servants and special advisers. It is a concept, not one official body with a single membership list.

The Prime Minister is the head of government. They normally lead the party that can command confidence in the House of Commons, appoint and dismiss ministers, chair Cabinet, decide the membership of Cabinet committees, and set the political direction of government.

Cabinet is the group of senior ministers, usually including the Chancellor, Secretaries of State and other senior office-holders. Formally, Cabinet is the senior collective decision-making body. In practice, its influence varies with the Prime Minister's style, the size of the government majority, party unity, the strength of senior ministers, and the urgency of the issue.

The phrase primus inter pares means "first among equals". It captures the traditional idea that the Prime Minister is the leading Cabinet minister, not a president. The tension is that modern Prime Ministers often look much more powerful than this phrase suggests because they control appointments, committees, the government agenda and the public presentation of policy.

This means PM power is never just personal. A Prime Minister may dominate, but they still need departments to implement policy, the Treasury to finance it, Cabinet colleagues to defend it, party MPs to vote for it, and Parliament to pass any necessary law.

Prime Minister and Cabinet

The relationship between the Prime Minister and Cabinet is central to this topic because it creates a permanent argument in UK politics: is the UK system still cabinet government, or has it become prime-ministerial government?

Cabinet government means major decisions are discussed and agreed collectively by senior ministers. This matters because Cabinet ministers bring departmental expertise, political authority and different viewpoints. A Foreign Secretary, Chancellor, Home Secretary or Defence Secretary may know risks that No. 10 alone would miss.

Prime-ministerial government means the Prime Minister and a small circle around them dominate decisions. This can happen through bilateral meetings, informal groups, Cabinet committees chaired by the PM, control of the agenda, media leadership, and the power to hire and fire ministers.

Both descriptions can be true in different circumstances. The UK constitution gives the Prime Minister strong political tools, but not a free hand. A Prime Minister with a large majority, party loyalty and a clear mandate can often dominate Cabinet. A Prime Minister facing rebellion, coalition, economic crisis or divided senior ministers may have to bargain.

An inner cabinet is an informal group of especially influential ministers and advisers around the Prime Minister. It is not a fixed constitutional body. Examples might include the PM, Chancellor and a few trusted senior ministers. Inner cabinets can make government faster and more strategic, but they can also sideline full Cabinet discussion.

The key AQA judgement is therefore not "PM powerful" or "Cabinet powerful" in the abstract. Strong answers ask: on this issue, who set the agenda, who had information, who could block the decision, and who had to defend the policy afterwards?

How Policy Is Made

Policy making is the process by which government turns political aims into decisions, rules, spending, laws and public services. It is not a neat single ladder. Some policy develops slowly through consultation and evidence. Some is made quickly in response to crisis. Some comes from manifesto promises, court decisions, pressure groups, civil service advice, ministerial priorities or international events.

A useful AQA model is:

The Treasury matters because most major policy needs money. A department may want a new programme, but the Treasury can require evidence, limit spending or insist on changes. The Cabinet Office matters because many problems cross departmental boundaries. For example, national security, public service reform, digital policy and emergency planning require several departments to coordinate.

Civil servants advise; ministers decide. This distinction matters. The Green Book supports evidence-based appraisal of options, but it does not make policy decisions. A minister may choose between options for political, financial, ethical or practical reasons. They then become accountable for that decision.

Policy can also become law. Green papers often ask questions, white papers set out firmer proposals, and bills become Acts if passed by Parliament and given Royal Assent. Not every policy needs an Act, but major changes often do.

Cabinet Committees

Cabinet committees are smaller groups of ministers that consider particular policy areas or cross-government problems. Their decisions have the same authority as Cabinet decisions, so they are not just discussion clubs. They are a major part of how the core executive manages policy making.

Cabinet committees matter for four reasons.

First, they reduce pressure on full Cabinet. Modern government is too large and complex for every issue to be discussed by all Cabinet ministers every week.

Second, they allow the right ministers to meet. A national security question needs the PM, Foreign Secretary, Defence Secretary, Home Secretary, Chancellor and intelligence-related advice more than it needs every departmental minister.

Third, they support collective responsibility. If the relevant ministers have been involved in the decision, it is easier to argue that the government has taken a collective decision that all ministers must defend.

Fourth, they can reveal the Prime Minister's priorities. The PM decides the committee structure, chairs some committees and chooses membership. The existence of committees on growth, national security, Europe, digital technology or resilience shows what the centre of government wants to coordinate.

As of the GOV.UK list updated on 11 May 2026, examples included:

Committees can strengthen government if they test evidence and resolve disputes. They can weaken collective government if they merely rubber-stamp decisions already made by No. 10 or an inner group. The issue is not whether a committee exists, but whether it gives ministers real information, time and influence.

Responsibility

Ministerial responsibility explains how executive power is supposed to be made answerable. AQA requires the difference between individual and collective responsibility.

Individual ministerial responsibility means a minister is accountable for their own conduct and for the policies, decisions and administration of their department. It does not always mean resignation. It can mean explaining, correcting, apologising, changing procedure or, in serious cases, leaving office.

The classic example is Sir Thomas Dugdale and Crichel Down in 1954. Dugdale resigned as Minister of Agriculture after an inquiry criticised how his department handled land that had been taken for wartime use and not returned properly. The constitutional point is that the minister answered to Parliament for departmental failure, even though officials had carried out much of the administration.

Collective responsibility means ministers can argue privately, but once the government has decided, they must publicly support the agreed line or resign. It has three linked parts:

Iain Duncan Smith's resignation in March 2016 is a useful post-1997 example. He resigned as Work and Pensions Secretary after disagreement over welfare policy. For AQA, the key point is not simply that a minister resigned, but why: a minister who cannot support the government's collective policy line cannot normally remain inside government while publicly opposing it.

Collective responsibility is powerful, but it is also flexible. It was formally set aside during the 2016 EU referendum campaign so ministers could campaign on different sides. It was also relaxed on some issues during the 2010-15 Conservative-Liberal Democrat coalition. This shows that collective responsibility is a convention controlled politically, especially by the Prime Minister, rather than a rigid statute.

The difference can be summarised simply:

Examples and Judgement

AQA expects examples from both 1945-1997 and 1997-present to show the power of the Prime Minister and Cabinet to dictate events and determine policy making. The best examples do more than name a policy. They show how executive power operated and what limited it.

These examples help students avoid a lazy conclusion. They show that the executive can be extremely powerful in setting policy, especially when the PM has a majority and Cabinet unity. But they also show that power is not the same as good process or guaranteed success.

The poll tax shows executive strength before 1997. The policy was pushed through despite fierce opposition. Yet the backlash damaged Thatcher's authority and helped expose the dependence of a Prime Minister on party support.

Iraq shows executive strength after 1997. Blair secured Cabinet and parliamentary backing for military action. Yet Chilcot's criticism matters because collective responsibility is only meaningful if ministers are properly informed and able to test policy before defending it.

For a strong AQA judgement, balance formal rules against political reality:

The lesson's core judgement is this: UK policy making is formally collective, but often Prime Minister-centred. Whether that produces strong government or weak scrutiny depends on how seriously Cabinet, committees and ministers test decisions before they are announced.
