The power of government

  • The UK government has significant power to make decisions and introduce laws

    • However, this power is not unlimited and is checked by other institutions

  • Parliament may need to agree to government proposals

    • MPs can debate, amend, or reject laws

  • The courts can intervene if the government acts unlawfully

    • The UK Supreme Court can rule that government actions or laws are unlawful

  • The public and the media can challenge the government

    • Protests, petitions, and media scrutiny can pressure the government to change course

Case Study

The prorogation of Parliament in 2019

Protesters hold red signs with "Reopen Parliament" and a padlock symbol, expressing a call to resume parliamentary activities.
  • In 2019, Prime Minister Boris Johnson advised the Queen to prorogue Parliament for five weeks

  • The Supreme Court ruled that the prorogation was unlawful, and Parliament was reopened

  • This showed that government power is limited by the rule of law

The Prime Minister and Cabinet

  • The Prime Minister is the head of the government, but the monarch is the Head of State

  • The Prime Minister is appointed by the Monarch

    • This usually happens after a general election or if a Prime Minister resigns

  • The Cabinet is made up of the most senior government ministers

    • Cabinet members are appointed, promoted or dismissed by the Prime Minister

    • The Prime Minister is often described as first amongst equals

      • This means they lead the Cabinet but are still part of a team

Key Cabinet roles

Position

Role

Chancellor of the Exchequer

  • Responsible for managing the UK’s economy, setting the government’s budget and deciding how public money is raised and spent

Home Secretary

  • Responsible for internal security, including policing, immigration, counter-terrorism and border control

Foreign Secretary

  • Manages the UK’s relationships with other countries, including diplomacy, international agreements and foreign policy

Defence Secretary

  • Responsible for the armed forces and national defence, including military operations and protecting the UK from external threats

Health Secretary

  • Oversees the National Health Service (NHS) and is responsible for health policy and public health in England

  • Collective responsibility means all Cabinet members must publicly support government decisions

    • If a minister disagrees, they are expected to resign

    • This principle helps ensure unity and stability in government

  • The Prime Minister is accountable to Parliament

    • They must answer questions and justify government actions

  • The Prime Minister is also accountable to their political party

    • Party members can remove a leader through a leadership challenge

    • Examples include Margaret Thatcher (1990) and Boris Johnson (2023)

Parliamentary sovereignty

  • Parliamentary sovereignty means that Parliament is the highest legal authority in the UK

    • Parliament can make or change any law

  • The government proposes laws, but Parliament decides whether they become law

  • Even governments with large majorities can face resistance

    • In 2025, Labour plans to cut welfare spending were withdrawn after 108 Labour MPs opposed them

  • This shows that Parliament can limit government power, even when the government is strong

Role of the legislature

  • The legislature refers to the bodies that make laws

    • In the UK, this is Parliament, made up of the House of Commons and House of Lords

Key roles

Lawmaking

Holding government to account

Platform for debate

  • Parliament debates the principles and details of laws

  • Amendments can be suggested and voted on

  • This includes questioning ministers and investigating government actions

  • MPs and Lords raise local, national, and international issues in the House of Commons and House of Lords

The House of Commons

  • This is the elected chamber of Parliament where MPs debate laws, represent their constituents, and hold the government to account

The House of Commons
  • MPs are elected by the public in general elections to represent local constituencies

  • There are 650 Members of Parliament (MPs), each representing a constituency

The House of Lords

  • This is the second chamber of Parliament that scrutinises, revises, and suggests amendments to laws proposed by the House of Commons

The House of Lords
  • Members are unelected and include life peers, bishops, and a small number of hereditary peers

  • here are around 780 members, and unlike the House of Commons, there is no fixed limit on its size

  • The House of Lords can delay and amend legislation but cannot ultimately block laws passed by the Commons

Opposition

  • The opposition includes all political parties not in government

  • The official opposition is the largest opposition party

    • Currently, this is the Conservative Party

    • The Leader of the Opposition receives a salary and special status, such as raising issues each week at Prime Ministers' Questions

  • The main role of the opposition is to hold the government to account

    • This is done through questioning, debates, and proposing alternatives

  • Opposition parties are given Opposition Days

    • On these occasions they can choose the topics for debate in Parliament

  • Opposition influence is stronger when the government has a small majority

    • With a large majority, governments usually pass their legislation unless their own MPs rebel

Political parties

  • A political party is an organisation of people who share similar ideas and policies

    • These ideas are known as an ideology

  • Parties stand candidates in elections to win power and form a government.

    • Party policies are set out in a manifesto, which is a list of promises made to voters

  • In a democracy, there is a choice of political parties

  • In a one-party state, only one political party is allowed

    • E.g. in China, the Communist Party is the single political party

Political parties in the UK

UK-wide political parties

Nationalist and regional parties

  • Labour Party

  • Conservative Party

  • Liberal Democrats

  • Reform UK

  • Green Party

  • Scottish National Party (SNP)

  • Plaid Cymru (Welsh nationalists)
