The Westminster Parliament
The UK Parliament sits at the Palace of Westminster in London and has two chambers:
- The House of Commons — 650 elected MPs (Members of Parliament), each representing one geographic constituency. The most important chamber.
- The House of Lords — around 800 members (the number varies). Not elected. Includes life peers (appointed for life), hereditary peers (most removed by the 1999 Act, 92 remain by election among themselves) and 26 senior Church of England bishops ("Lords Spiritual").
The Government, the Prime Minister, the Cabinet
The leader of the political party that wins a majority in the House of Commons becomes Prime Minister. The PM appoints the Cabinet — around 20 senior ministers — and lives at 10 Downing Street. Key Cabinet positions include the Chancellor of the Exchequer (finance, lives at 11 Downing Street), the Home Secretary (immigration, policing, security), the Foreign Secretary (foreign affairs), and the Lord Chancellor (justice). The largest party not in government forms the Opposition, led by the Leader of the Opposition; the Opposition has a parallel Shadow Cabinet.
The monarchy
The UK is a constitutional monarchy — the monarch (currently King Charles III, who acceded on 8 September 2022; the handbook predates this and refers to Queen Elizabeth II) is head of state but does not rule. The monarch's role is largely ceremonial:
- Opens new sessions of Parliament with the State Opening
- Gives Royal Assent to bills passed by Parliament (the moment they become law)
- Appoints the Prime Minister (in practice always the leader of the largest party)
- Acts as Head of the Commonwealth, head of the armed forces and Supreme Governor of the Church of England
Devolution: Scotland, Wales, Northern Ireland
In 1997 referendums approved devolved governments for Scotland and Wales; the Good Friday Agreement (1998) restored a power-sharing assembly in Northern Ireland. All three opened in 1999:
- Scottish Parliament — sits at Holyrood in Edinburgh — 129 MSPs (Members of the Scottish Parliament) — has power over health, education, justice, transport, environment, and limited tax-raising
- Senedd (Welsh Parliament) — sits at the Senedd building in Cardiff Bay — was renamed from "National Assembly for Wales" in 2020. 60 elected members.
- Northern Ireland Assembly — sits at Stormont — 90 elected members, governs on a power-sharing basis between unionist and nationalist parties
Elections and voting
- General elections are held at least every 5 years (fixed-term since 2011, but a 2022 Act gives the PM more flexibility). You vote for an MP to represent your constituency.
- The voting system is first-past-the-post — whoever gets the most votes in each constituency wins; no preferences, no run-offs.
- You can vote if you are 18 or over and a British, Irish or qualifying Commonwealth citizen resident in the UK. In Scotland and Wales, 16- and 17-year-olds can vote in local and devolved elections.
- To vote you must be on the electoral register. Register at gov.uk/register-to-vote.
- From 2023, voting in person requires photo ID.
The courts and the law
The UK has separate legal systems:
- England and Wales — one combined system based on common law
- Scotland — its own legal system, partly based on Roman law
- Northern Ireland — its own system similar to England and Wales
- Magistrates' Courts — handle minor criminal cases and family matters. Magistrates are usually unpaid volunteers from the community.
- Crown Court — serious criminal cases, heard by a judge and jury of 12. Trial by jury is a fundamental right.
- County Courts — civil cases (debt, family disputes, personal injury)
- The High Court — major civil and serious criminal appeals
- Court of Appeal
- The Supreme Court — the final court of appeal for civil cases throughout the UK and criminal cases in England, Wales and Northern Ireland. Created in 2009, replacing the judicial role of the House of Lords. Scotland's criminal cases end at the High Court of Justiciary.
Your duties as a UK citizen or resident
Beyond obeying the law, the handbook lists civic duties:
- Paying taxes — income tax, National Insurance, council tax, VAT
- Jury service — anyone on the electoral register between 18 and 75 can be summoned for jury duty. You must serve unless excused for a specific reason.
- Registering to vote — you must be on the electoral register at your address
- Reporting crime — call 999 for emergencies, 101 for non-emergencies
- Looking after the local environment — recycling, not dropping litter, respecting your neighbours
Money, banking and the cost of living
Bank accounts are easy to open with proof of ID and address. The Bank of England is the UK's central bank, sets interest rates (via the Monetary Policy Committee). Income tax is collected through PAYE (Pay As You Earn) for employees; self-employed people use Self Assessment. The standard rate of VAT is 20%. Council Tax funds local services (rubbish, schools, social care) and varies by property value and local authority. National Insurance contributions fund the state pension and some benefits.
Drill this chapter hard
Government and Law is 25% of the test and packed with specific numbers and names. The Government topic page has live questions. The Government Numbers cheat sheet compresses MP counts, voting ages, election cycles and court hierarchy onto one printable page. If you can recite "650 MPs, 5-year max parliaments, 18 to vote, 12-person jury", you're most of the way there.
