What this dot point is asking
This WJEC AS topic asks you to explain how the UK executive is organised and to evaluate whether the Prime Minister has become too powerful. You need the roles of the PM and Cabinet, the idea of the core executive, prerogative powers, the conventions of ministerial responsibility, and the factors that strengthen or limit prime ministerial power.
The answer
The Prime Minister and the core executive
The Prime Minister is the head of government, leader of the largest party in the Commons, and the public face of the executive. The PM directs policy, manages the government and represents the UK abroad.
The powers of the Prime Minister
The Cabinet and collective responsibility
The Cabinet is the committee of around twenty senior ministers that takes or ratifies major decisions. It operates under collective ministerial responsibility: once a decision is made, all ministers must publicly support it or resign, which keeps the government united in public. Much detailed work is done in Cabinet committees and through bilateral discussions between the PM and individual ministers.
Individual ministerial responsibility
Under individual ministerial responsibility, each minister is accountable to Parliament for their own conduct and the running of their department. In serious cases of personal misconduct or departmental failure, the convention is that a minister may be expected to resign, though in practice resignations depend heavily on political circumstances and the PM's support.
Is the Prime Minister too powerful?
This is the central evaluative debate. Those who argue the office has become too powerful or "presidential" point to the dominance of patronage, prerogative powers, control of the media and the policy agenda, and the eclipse of full Cabinet government by a more personal style of leadership. Those who stress the limits point out that the PM relies on the support of party and Cabinet, must hold a Commons majority, and can be removed by their own party. Prime ministerial power therefore varies with circumstances, especially the size of the majority and the unity of the party.
Examples in context
Power that depends on circumstances. The case that a Prime Minister is constrained rather than all-powerful is shown when a PM loses the confidence of their own party or Cabinet and is forced out, despite holding all the formal levers of patronage and prerogative. A leader with a large, united majority can dominate; one whose party turns against them can fall quickly. This is why the strongest essays argue that prime ministerial power is contingent on majority size and party support, not fixed by the office alone.

WJEC AS Unit 110 marksExplain the powers of the Prime Minister.Show worked answer →
A short-answer question testing AO1 knowledge of the executive.
The Prime Minister's powers include: appointing and dismissing ministers (patronage), chairing Cabinet and controlling its agenda, directing government policy and strategy, representing the UK abroad, and exercising prerogative powers (such as deploying the armed forces and making senior appointments). The PM is also leader of the largest party and the public face of the government.
The best answers explain how each power is used and note that they are exercised subject to party support and the need to retain a Commons majority, rather than simply listing them.
WJEC AS Unit 120 marksTo what extent has the office of Prime Minister become too powerful?Show worked answer →
An extended evaluation requiring a balanced judgement.
Case that the PM is too powerful: control of patronage, the use of prerogative powers, dominance of the media and the policy agenda, and the decline of full Cabinet government toward more personal or "presidential" leadership.
Case for limits: the PM depends on the support of party and Cabinet (resignations and rebellions can be fatal), must command a Commons majority, faces the press, courts and devolved bodies, and can be removed by their own party.
The top band weighs the resources of the office against the constraints, often arguing that power depends on circumstances such as majority size and party unity, and reaches a supported judgement.
