The UK government, the law and your role

The UK Government and Constitution

The UK is a parliamentary democracy with the monarch as head of state. Its constitution is unwritten, having evolved over centuries rather than resulting from a single revolution. Key institutions include the monarchy, Parliament (House of Commons and House of Lords), the Prime Minister, the Cabinet, the judiciary, the police, the civil service, and local government.

Parliament

The House of Commons is the more powerful chamber; its members (MPs) are democratically elected via a 'first past the post' system in constituency elections held at least every five years. The House of Lords consists of life peers, appointed on the Prime Minister's advice, and a small number of elected hereditary peers. Lords are not elected and do not represent constituencies. The Speaker chairs Commons debates, maintains order, and is chosen by MPs by secret ballot.

The Monarchy

The monarch appoints the Prime Minister — normally the leader of the party with the most MPs — but does not govern directly. King Charles III has reigned since 2022; his heir apparent is William, Prince of Wales. The national anthem is 'God Save the King'.

Devolved Administrations

Since 1999, Scotland, Wales and Northern Ireland have had their own devolved legislatures. The Scottish Parliament (129 MSPs, Edinburgh) can legislate on matters including health, education and civil law. The Welsh Senedd (60 AMs, Cardiff) covers 20 areas including housing and education. The Northern Ireland Assembly (90 MLAs, Stormont) was established following the 1998 Good Friday Agreement and operates on a power-sharing basis.

Voting and Elections

The voting age is 18. UK citizens, Commonwealth citizens and Irish Republic citizens resident in the UK may vote in all public elections. EU citizens resident in the UK may vote in all elections except General Elections. Voters must be on the electoral register. MPs are elected by first past the post; MEPs used proportional representation.

Law and Courts

Criminal law covers offences investigated by authorities and punished by courts; civil law resolves disputes between individuals or organisations. Minor criminal cases in England and Wales are heard in Magistrates' Courts; serious cases go to Crown Court before a judge and a 12-person jury. Scotland uses Sheriff Courts and a 15-person jury, with a unique 'not proven' verdict available. Civil disputes are handled in County Courts or, for smaller claims under £10,000 (£5,000 in Scotland and Northern Ireland), through the small claims procedure.

International Organisations

The Commonwealth has 56 member states and King Charles III as its ceremonial head. The UK left the EU on 31 January 2020. The Council of Europe (47 members) oversees the European Convention on Human Rights. The UK is a permanent member of the UN Security Council and a founding member of NATO.
