UK Parliament in the context of "Fifth Periodic Review of Westminster constituencies"

An act of Parliament in the United Kingdom is primary legislation passed by the UK Parliament in Westminster, London.

An act of Parliament can be enforced in all four of the UK constituent countries (England, Scotland, Wales and Northern Ireland). As a result of devolution the majority of acts that are passed by Parliament increasingly only apply either to England and Wales only, or England only. Generally acts only relating to constitutional and reserved matters now apply to the whole of the United Kingdom.

Mary Somerville (née Fairfax, formerly Greig; 1780–1872) was a Scottish scientist, writer, and polymath. She studied mathematics and astronomy, and in 1835 she and Caroline Herschel were elected as the first female Honorary Members of the Royal Astronomical Society.

In John Stuart Mill's 1866 mass petition to the UK Parliament to grant women the right to vote, the first signature on the petition was Somerville's, which she signed before the age of 86.

Referendums in the United Kingdom are occasionally held at a national, regional or local level. Historically, national referendums are rare due to the long-standing principle of parliamentary sovereignty. Legally there is no constitutional requirement to hold a national referendum for any purpose or on any issue. However, the UK Parliament is free to legislate through an Act of Parliament for a referendum to be held on any question at any time.

National referendums are regulated by the Political Parties, Elections and Referendums Act 2000 which also regulates for regional and local referendums in England, Northern Ireland and Wales. In Scotland referendums on devolved matters are regulated under the Referendums (Scotland) Act 2020.

Politics in Wales forms a distinctive polity in the wider politics of the United Kingdom, with Wales as one of the four constituent countries of the United Kingdom (UK).

Constitutionally, the United Kingdom is a unitary state with one sovereign parliament delegating power to the devolved national parliaments, with some executive powers divided between governments. Under a system of devolution adopted in the late 1990s three of the four countries of the United Kingdom, Wales, Scotland and Northern Ireland, voted for limited self-government, subject to the ability of the UK Parliament in Westminster, nominally at will, to amend, change, broaden or abolish the national governmental systems. As such, the Senedd (Welsh Parliament; Welsh: Senedd Cymru) is not de jure sovereign. Since then, further Welsh devolution has granted the Senedd additional powers.

Stafford is a constituency represented in the House of Commons of the UK Parliament since 2024 by Leigh Ingham from the Labour Party.

The seat since its resurrection in 1983 has been of a bellwether being held always by the incumbent government.

The 2016 United Kingdom European Union membership referendum, commonly referred to as the EU referendum or the Brexit referendum, was a referendum that took place on 23 June 2016 in the United Kingdom (UK) and Gibraltar under the provisions of the European Union Referendum Act 2015 to ask the electorate whether the country should continue to remain a member of, or leave, the European Union (EU). The result was a vote in favour of leaving the EU, triggering calls to begin the process of the country's withdrawal from the EU commonly termed "Brexit".

Since 1973, the UK had been a member state of the EU and its predecessor the European Communities (principally the European Economic Community), along with other international bodies. The constitutional implications of membership for the UK became a topic of debate domestically particularly regarding sovereignty. A referendum on continued membership of the European Communities (EC) to try and settle the issue was held in 1975, with 67% of voters approving continued membership. Between 1975 and 2016 as European integration deepened, subsequent EC/EU treaties and agreements were ratified by the UK Parliament but without any public approval. Following the Conservative Party's victory at the 2015 general election as a main manifesto pledge, the legal basis for the EU referendum was established through the European Union Referendum Act 2015. Prime Minister David Cameron also oversaw a renegotiation of the terms of EU membership, intending to implement these changes in the event of a Remain result. The referendum was legally non-binding due to the ancient principle of parliamentary sovereignty, although the government promised to implement the result.
