Executive, legislature, judiciary and monarchy

The role of the monarchy

  • The monarchy is the King, who is the head of state and carries out ceremonial duties with limited political power

  •  The UK is a constitutional monarchy

    • King Charles III is the formal, symbolic leader of the country, while elected politicians run the government

  • Laws are made by Parliament in the monarch’s name, and the monarch carries out key constitutional roles

    • Example include opening Parliament, appointing the Prime Minister and giving Royal Assent to laws

  • The Monarch is neutral and carries out their role on the advice of the government, ensuring democracy is respected

The role of the legislature

  • The legislature is Parliament, which debates, makes and changes laws and checks the work of the government

  • Parliament is made up of the House of Commons and the House of Lords

    • It is where important national decisions are debated and made

  • The UK has a bicameral Parliament, which means it has two chambers

    • The House of Commons is made up of elected MPs who represent constituencies

    • The House of Lords is made up of unelected members who examine laws in detail

  • Parliament acts as the legislature, meaning it is the body that makes, debates and amends laws

    • For example, a new law about education or policing must be debated and approved by both Houses before it can become law

  • Parliament also has an important role in scrutinising the government

    • MPs question ministers, debate government policies and can vote against government proposals

The role of the Executive

  • The Executive is the part of government responsible for running the country on a day-to-day basis and makes decisions

    • It is made up of the Prime Minister, government ministers, senior civil servants, and political advisers

  • The Executive is responsible for developing government policy

    • For example, ministers decide plans for areas such as education, health or defence, which are then turned into laws by Parliament

  • The Executive is also responsible for putting laws and policies into action

    • Government departments, such as the Department of Health or the Home Office, are run by ministers and civil servants

  • The Executive plays a key role in crisis management

    • For example, during emergencies such as public health crises or national security threats, the Executive makes quick decisions to protect the public

  • Although powerful, the Executive is accountable to Parliament

    • Ministers must explain and justify their actions to MPs, helping to prevent misuse of power

The role of the judiciary

  • The judiciary is the system of courts and judges that interprets and applies the law and makes sure it is followed fairly

  • In the UK, the judiciary (judges and courts) is independent of the government

    • Judges are appointed based on experience and ability, not politics, and usually remain in post until retirement

    • This independence helps protect the rule of law and ensures fair decisions

  • The creation of the UK Supreme Court in 2009 strengthened judicial independence

  • The Supreme Court is separate from Parliament and government

    • It can make important judgements about whether the government has acted lawfully

  • The Supreme Court can decide whether new laws are compatible with the Human Rights Act 1998

    • If a law breaches human rights, the Court can issue a declaration of incompatibility

    • Parliament then decides whether to change the law

  • The Supreme Court also oversees devolution arrangements

    • It can rule on whether laws passed by the Scottish Parliament, Senedd or Northern Ireland Assembly go beyond their powers

  • The Court played a major role during the Brexit process

    • In 2017, it ruled that Parliament must approve triggering Brexit

    • In 2019, it ruled that the government’s suspension of Parliament was unlawful

Examiner Tips and Tricks

  • A common mistake is saying the monarch makes political decisions

  • In exam answers, be clear that real power sits with Parliament and the Executive

  • Credit is gained by explaining that the monarch acts on advice and follows convention, especially for roles like Royal Assent and appointing the Prime Minister

The House of Commons

Green leather benches face each other in a narrow chamber with oak panelling, despatch boxes, and the Speaker’s chair.
  • The House of Commons is made up of 650 elected Members of Parliament (MPs)

    • MPs are elected by voters in constituencies across the UK

    • MPs usually work full time representing the interests of their constituents

  • The House of Commons is responsible for forming the government

    • The government is formed by the political party or parties that can command a majority in the House of Commons

    • The Prime Minister and most senior government ministers are normally members of the House of Commons

  • The House of Commons has the main law-making power in Parliament

    • The House of Commons determines the final outcome of most legislation

    • The House of Commons can reject or overturn changes suggested by the House of Lords

  • The House of Commons scrutinises the work of the government

    • MPs hold the government to account through debates, select committees and Prime Minister’s Questions

  • The House of Commons controls confidence in the government

    • A vote of no confidence in the government can lead to the government resigning or a general election

Parliamentary debate

  • Parliamentary debate is a formal discussion of issues, laws and policies in Parliament, where MPs and peers speak for or against proposals in the House of Commons and House of Lords

  • This debate allows ideas to be examined in detail

    • Different viewpoints and evidence can be considered before decisions are made

  • Debate helps to shape legislation

    • Bills can be challenged, improved and amended as a result of discussion

  • Parliamentary debate holds the government to account

    • Ministers must explain and defend their policies in public

  • Debate supports democracy

    • It ensures laws and policies are not rushed and reflect a range of opinions

The House of Lords

Red leather benches line a grand chamber with gilded woodwork, ornate carvings, the Woolsack, and robed peers seated formally
  • The House of Lords is made up of over 800 members

    • Members include life peers, crossbench peers, bishops of the Church of England and hereditary peers

      • The government has proposed removing hereditary peers from the House of Lords

  • Members of the House of Lords are not elected

    • Peers are appointed or inherit their position rather than being chosen by voters

    • Members are paid a daily allowance for attending the House of Lords

  • The House of Lords plays a key role in revising legislation

    • It debates proposed laws and suggests amendments to improve them

    • Members often use their specialist knowledge and experience during debates

  • The House of Lords scrutinises government decisions

    • It checks and examines legislation in detail before it becomes law

  • The powers of the House of Lords are limited

    • The House of Lords cannot interfere with financial bills such as the Budget

    • The House of Lords cannot block the House of Commons in the long term
