What is the Cabinet?

  • The Cabinet is a committee of senior ministers, usually around 20–25, chaired by the Prime Minister

  • It is the central decision-making body of the UK executive

    • Cabinet ministers are collectively responsible for government policy and are typically the heads of major government departments

The role of the Cabinet

PM Keir Starmer chairs a Cabinet meeting in late 2025 - MPs sit along both sides of a long table, with large windows in the background

  • Discussing and agreeing major government policy

  • Coordinating the work of different government departments

  • Resolving disputes between ministers

  • Providing political legitimacy for executive decisions

  • Acting as a forum for collective decision-making

The Prime Minister’s role in relation to the Cabinet

  • The Prime Minister is the head of the Cabinet and controls its membership and operation.

  • The PM:

    • appoints and dismisses Cabinet ministers

    • chairs Cabinet meetings

    • sets the Cabinet agenda

    • determines the structure and membership of Cabinet committees

Factors affecting the Prime Minister’s choice of Cabinet Ministers

  • As head of the Cabinet, the Prime Minister uses cabinet appointments strategically to balance political authority, party unity and effective government

1. Loyalty to the Prime Minister

  • PMs often reward personal loyalty

  • Loyal ministers are less likely to challenge the PM publicly or in Cabinet

Examples

  • Rishi Sunak appointed Jeremy Hunt as Chancellor (2022) as a stabilising and loyal figure

  • Boris Johnson promoted Priti Patel and Dominic Raab (2019) due to their loyalty during the Brexit debates

2. Balancing party factions

  • Cabinets often reflect different ideological strands within the governing party

  • Balancing factions helps prevent rebellions and leadership challenges

Examples

  • David Cameron appointed Eurosceptic Iain Duncan Smith alongside pro-EU figures such as Philip Hammond

  • Keir Starmer appointed both soft left ministers like Angela Rayner and centrists like Rachel Reeves

3. Ministerial experience and competence

  • PMs select ministers capable of running complex departments

  • Experience increases credibility and effectiveness

Example

  • Starmer’s 2024 Cabinet emphasised experience, including Yvette Cooper’s appointment to the Home Office

4. Public image and media handling

  • High-profile departments require ministers able to withstand media pressure

Example

  • Wes Streeting was appointed to Health in 2024 partly due to his communication skills

5. Representational diversity

  • PMs aim to make cabinets appear representative in terms of gender, ethnicity and background

Example

  • The appointment of Heidi Alexander to the Transport Department in 2024 meant the Cabinet was entirely state-school educated for the first time

The relationship between the Prime Minister and the Cabinet

  • The balance of power between the Prime Minister and Cabinet varies depending on political circumstances and leadership style

Prime Ministerial leadership style

  • Some PMs adopt a collective style, relying on Cabinet discussion

  • Others adopt a more presidential style, relying on informal decision-making

Examples

  • Tony Blair used sofa government and informal meetings rather than full Cabinet discussion

  • The Coalition government relied on The Quad rather than the full Cabinet

  • Boris Johnson relied heavily on advisers such as Dominic Cummings, causing tension with senior ministers

Party unity and parliamentary majority

  • A united party and large majority strengthens PM dominance

  • Division or minority status increases Cabinet influence

Examples

  • John Major’s divided government reduced his authority

  • Boris Johnson’s 80-seat majority (2019) strengthened his control

  • Despite a large majority in 2024, Keir Starmer faced early Cabinet tensions

External crises

  • Crises can:

    • increase Cabinet coordination

    • or centralise power around the Prime Minister

Examples

  • Covid-19 initially strengthened Cabinet coordination through COBRA

    • Later stages caused divisions, including disagreements between Sunak and Gove

  • Liz Truss’s mini-budget crisis (2022) led to Cabinet breakdown and loss of authority

Is the Cabinet significant?

The Cabinet is significant

The Cabinet is not significant

Can block or change policy

  • Cabinet opposition can force Prime Ministers to abandon or amend proposals, weakening PM authority

  • E.g. Cameron dropped disability benefit cuts (2016); Starmer modified the two-child benefit cap (2025)

PM can bypass Cabinet

  • Prime Ministers may rely on informal groups or advisers rather than full Cabinet discussion

  • E.g. Blair’s sofa government; Johnson’s reliance on Dominic Cummings

Can force PM resignation

  • Mass Cabinet resignations make governing impossible and undermine legitimacy

  • E.g. Johnson resigned in 2022 after over 50 ministers quit

Patronage limits independence

  • Cabinet ministers depend on PM appointment and dismissal powers, reducing their willingness to challenge decisions

  • E.g. Johnson’s 2019 Cabinet reshuffle

Cabinet committees matter

  • Committees can take binding decisions across government

  • E.g. COVID-O committee shaped lockdown policy

Rubber-stamping role

  • Cabinet may approve decisions already taken elsewhere for legitimacy

  • E.g. Truss’s Cabinet endorsing the 2022 mini-budget

Represents party factions

  • Balancing factions helps maintain party unity and government stability

PM controls committees

  • The PM decides which Cabinet committees exist, who sits on them, and what they consider
