The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation.
The United Kingdom is a constitutional monarchy which, by legislation and convention, operates as a unitary parliamentary democracy. A hereditary monarch, currently King Charles III, serves as head of state while the Prime Minister of the United Kingdom, currently Sir Keir Starmer since 2024, serves as the elected head of government.
The legislatures of the United Kingdom are derived from a number of different sources. The Parliament of the United Kingdom is the supreme legislative body for the United Kingdom and the British overseas territories with Scotland, Wales and Northern Ireland each having their own devolved legislatures. Each of the three major jurisdictions of the United Kingdom has its own laws and legal system.
The Parliament Acts 1911 and 1949 are two Acts of the Parliament of the United Kingdom, which form part of the constitution of the United Kingdom. Section 2(2) of the Parliament Act 1949 provides that the two Acts are to be construed as one.
The House of Lords Act 1999 is an act of the Parliament of the United Kingdom that reformed the House of Lords, one of the chambers of Parliament. The Act was given royal assent on 11 November 1999. For centuries, the House of Lords had included several hundred members who inherited their seats ; the Act removed such a right. However, as part of a compromise, the Act allowed ninety-two hereditary peers to remain in the House. Another ten were created life peers to enable them to remain in the House.
The Sexual Offences (Amendment) Act 2000 (c.44) is an Act of the Parliament of the United Kingdom. It set the age of consent for male homosexual sexual activities and for heterosexual anal sex at 16, which had long been the age of consent for all other types of sexual activities, such as vaginal sex or lesbian sex. As such, it made the age of consent for all types of sexual acts equal, without discrimimating on the basis of the type of act or of the sexes of those involved in the act. It also introduced the new offence of 'having sexual intercourse or engaging in any other sexual activity with a person under 18 if in a position of trust in relation to that person'.
The War Crimes Act 1991 is an Act of the Parliament of the United Kingdom. It confers jurisdiction on courts in the United Kingdom to try people for war crimes committed in Nazi Germany or German-occupied territory during the Second World War by people who were not British citizens at the time but have since become British citizens or residents. The legislation was enacted as there were no provisions to allow the extradition of British residents or naturalised citizens to face trial for war crimes in third countries at the time. Other countries, such as the United States, have used civil rather than criminal proceedings to resolve this issue by revoking citizenship of suspects, therefore facilitating their deportation.
The 1999 European Parliament election was the United Kingdom's part of the European Parliament election 1999. It was held on 10 June 1999. Following the European Parliamentary Elections Act 1999, it was the first European election to be held in the United Kingdom where the whole country used a system of proportional representation. In total, 87 Members of the European Parliament were elected from the United Kingdom across twelve new regional constituencies.

The reform of the House of Lords, the upper house of the Parliament of the United Kingdom, has been a topic of discussion in UK politics for more than a century. Multiple governments have attempted reform, beginning with the introduction of the Parliament Act 1911 by the incumbent Liberal Government. When the Labour Party came to power in the 1997 general election, the Blair government passed the House of Lords Act 1999. On 7 November 2001 the government undertook a public consultation. This helped to create a public debate on the issue of Lords reform, with 1,101 consultation responses and numerous debates in Parliament and the media. However, no consensus on the future of the upper chamber emerged.

The Senedd constituencies and electoral regions are the electoral districts used to elect members of the Senedd to the Senedd, and have been used in some form since the first election of the then National Assembly for Wales in 1999.

The five electoral regions are: Mid and West Wales, North Wales, South Wales Central, South Wales East, and South Wales West, with the forty constituencies listed below. Voting last took place in all districts in the 2021 Senedd election, and is not used for local government.
The Criminal Justice (Scotland) Act 1980 is an act of Parliament in the United Kingdom. Most of the act's provisions were merely a consolidation of already existing legislation, and as such subject to little controversy, with the notable exception was section 80, which partially decriminalised private homosexual acts between consenting adults in Scotland.

The act was intended, in particular, to facilitate the preparation of a revised edition of the statutes.

The act was intended, in particular, to make the revised edition of the statutes already published applicable to Ireland.
In the Parliament of the United Kingdom, a reasoned amendment is an amendment to the wording of the motion on the reading of a bill, which turns the motion from one progressing the bill into one rejecting it. It is sometimes called a wrecking amendment, but the term wrecking amendment more often denotes a type of amendment to the bill itself, rather than to a motion on reading the bill. The term "reasoned amendment" reflects the fact that the amended motion specifies reasons for rejecting the bill.
