2024 United Kingdom general election in the context of "Maidenhead (UK Parliament constituency)"

The Parliament of the United Kingdom currently has 650 parliamentary constituencies across the constituent countries (England, Scotland, Wales, and Northern Ireland), each electing a single member of parliament (MP) to the House of Commons by the plurality (first-past-the-post) voting system, ordinarily every five years. Voting last took place in all 650 of those constituencies at the United Kingdom general election on 4 July 2024.

The number of seats rose from 646 to 650 at the 2010 general election after proposals made by the boundary commissions for England, Wales, and Northern Ireland (the Fifth Periodic Review of Westminster constituencies) were adopted through statutory instruments. Constituencies in Scotland remained unchanged, as the Boundary Commission for Scotland had completed a review just before the 2005 general election, which had resulted in a reduction of 13 seats.

His Majesty's Government, abbreviated to HM Government or otherwise UK Government, is the central executive authority of the United Kingdom of Great Britain and Northern Ireland. The government is led by the prime minister (Keir Starmer since 5 July 2024) who selects all the other ministers. The government is currently supported by the Labour party, which has had a majority in the House of Commons since 2024. The prime minister and his most senior ministers belong to the supreme decision-making committee, known as the Cabinet.

Ministers of the Crown are responsible to the House in which they sit; they make statements in that House and take questions from members of that House. For most senior ministers this is usually the elected House of Commons rather than the House of Lords. The government is dependent on Parliament to make primary legislation, and general elections are held at least once every five years to elect a new House of Commons, unless the prime minister advises the monarch to dissolve Parliament, in which case an election may be held sooner. After an election, the monarch selects as prime minister the leader of the party most likely to command the confidence of the House of Commons, usually by possessing a majority of MPs.

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 head of the elected government.

Under the United Kingdom's parliamentary system, executive power is exercised by His Majesty's Government, whose prime minister is formally appointed by the king to act in his name. The king must appoint a member of parliament that can command the confidence of the House of Commons, usually the leader of the majority party or apparent majority party, though the king may choose to appoint an alternative if they say that they cannot expect the confidence of the House. Having taken office, the prime minister can then appoint all other ministers from parliament.

The Labour Party, commonly Labour, is one of the two main political parties in the United Kingdom, along with the Conservative Party. It sits on the centre-left of the left–right political spectrum, and has been described as an alliance of social democrats, democratic socialists and trade unionists. It has been the governing party since the 2024 general election. Keir Starmer has been Leader of the Labour Party since 2020 and Prime Minister of the United Kingdom since 2024. There have been twelve Labour governments and seven Labour prime ministers.

The Labour Party was founded in 1900, having emerged from the trade union movement and socialist parties of the 19th century. It was electorally weak before the First World War, but in the early 1920s overtook the Liberal Party to become the main opposition to the Conservative Party, and briefly formed a minority government under Ramsay MacDonald in 1924. In 1929 Labour for the first time became the largest party in the House of Commons, with 287 seats, but fell short of a majority, forming another minority government. In 1931, in response to the Great Depression, MacDonald formed a new government with Conservative and Liberal support, which led to his expulsion from the party. Labour was soundly defeated by his coalition in 1931, winning only 52 seats, but began to recover in 1935 with 154 seats.

The dissolution of the Parliament of the United Kingdom occurs automatically five years after the day on which Parliament first met following a general election, or on an earlier date by royal proclamation at the advice of the prime minister. The monarch's prerogative power to dissolve Parliament was revived by the Dissolution and Calling of Parliament Act 2022, which also repealed the Fixed-term Parliaments Act 2011. By virtue of amendments made by the Dissolution and Calling of Parliament Act to Schedule 1 to the Representation of the People Act 1983, the dissolution of Parliament automatically triggers a general election.

The last dissolution of Parliament occurred on 30 May 2024, following the announcement that the 2024 general election would be held on 4 July.

The 2010 United Kingdom general election was held on Thursday 6 May 2010, to elect 650 Members of Parliament (or MPs) to the House of Commons. This was the first election to be held after the minimum age of candidacy was reduced from 21 to 18.

It resulted in the Labour government losing its 66-seat majority to the Conservative opposition; however, with the Conservatives only having 306 elected MPs, this election resulted in the first hung parliament since February 1974. This election marked the start of a Conservative government that would last for 14 years until its ousting in 2024.

The 2005 United Kingdom general election was held on Thursday 5 May 2005, to elect 646 members to the House of Commons. The governing Labour Party led by Prime Minister Tony Blair won its third consecutive victory, with Blair becoming the second Labour leader after Harold Wilson to form three majority governments. However, its majority fell to 66 seats; the majority it won four years earlier had been of 167 seats. The UK media interpreted the results as an indicator of a breakdown in trust in the government, and especially in Blair.

This was the first time the Labour Party had won a third consecutive election, but would be the last election victory for Labour until 2024. The Liberal Democrats, led by Charles Kennedy, increased its seat count for a third consecutive election, netting the most seats in its history until 2024 and the most of any of the connected British Liberal parties since 1929. The Labour campaign emphasised a strong economy; however, Blair had suffered a decline in popularity, which was exacerbated by the controversial decision to send British troops to invade Iraq in 2003. Despite this, Labour mostly retained its leads over the Conservatives in opinion polls on economic competence and leadership, and Conservative leaders Iain Duncan Smith (2001–2003) and Michael Howard (2003–2005) struggled to capitalise on Blair's unpopularity, with the party consistently trailing behind Labour in the polls throughout the 2001–2005 parliament. The Conservatives campaigned on policies such as immigration limits, improving poorly managed hospitals, and reducing high crime rates. The Liberal Democrats took a strong stance against the Iraq War, particularly due to the absence of a second United Nations resolution; this anti-war position resonated with disenchanted Labour voters, leading to the Liberal Democrats achieving what was at that point their largest vote share in their history.

The Conservative and Unionist Party, commonly the Conservative Party and colloquially the Tories, is one of the two main political parties in the United Kingdom, along with the Labour Party. It sits on the centre-right to right-wing of the left–right political spectrum. Following its defeat by Labour at the 2024 general election it is currently the second-largest party by the number of votes cast and number of seats in the House of Commons; as such it has the formal parliamentary role of His Majesty's Most Loyal Opposition. It encompasses various ideological factions including one-nation conservatives, Thatcherites and traditionalist conservatives. There have been 20 Conservative prime ministers.

The Conservative Party was founded in 1834 from the Tory Party and was one of two dominant political parties in the 19th century, along with the Liberal Party. Under Benjamin Disraeli it played a preeminent role in politics at the height of the British Empire. In 1912 the Liberal Unionist Party merged with the party to form the Conservative and Unionist Party. Its rivalry with the Labour Party has shaped modern British politics for the last century. David Cameron sought to modernise the party after his election as leader in 2005, and the party governed from 2010 to 2024 under five prime ministers, latterly Rishi Sunak.
