Plurality voting refers to electoral systems in which a candidate who polls more than any other is elected. In systems based on single-member districts, it elects just one member per district and may also be referred to as first-past-the-post (FPTP), single-member plurality (SMP/SMDP), single-choice voting, simple plurality or relative majority. A system that elects multiple winners elected at once with the plurality rule, such as casting of multiple X votes in a multi-seat district, is referred to as plurality block voting.
The additional-member system (AMS) is a mixed electoral system under which most representatives are elected in single-member districts (SMDs), and the other "additional members" are elected to make the seat distribution in the chamber more proportional to the way votes are cast for party lists. It is distinct from parallel voting in that the "additional member" seats are awarded to parties taking into account seats won in SMDs, which is not done under parallel voting.
First-past-the-post voting is an electoral system wherein voters cast a vote for a single candidate, and the candidate with the most votes wins the election. Analogous systems for multi-winner contests are known as plurality block voting or "block voting" systems; both FPTP and block voting are "plurality" systems in that the winner needs only a plurality of the votes and not an absolute majority. The term first-past-the-post is a metaphor from horse racing of the plurality-voted candidate winning such a race; the electoral system is formally called single-member plurality voting (SMP) when used in single-member districts, and informally called choose-one voting in contrast to ranked voting or score voting.
The October 1974 United Kingdom general election took place on Thursday 10 October 1974 to elect 635 members of the British House of Commons. It was the second general election held that year; the first year that two general elections were held in the same year since 1910; and the first time that two general elections were held less than a year apart from each other since the 1923 and 1924 elections, which took place 10 months apart. The election resulted in the Labour Party, led by Prime Minister Harold Wilson, winning a bare majority of three seats. That enabled the remainder of the Labour government to take place, but it saw a gradual loss of its majority.
The 1950 United Kingdom general election was the first ever to be held after a full term of Labour government. The election was held on Thursday 23 February 1950, and was the first held following the abolition of plural voting and university constituencies. The government's 1945 lead over the Conservative Party shrank dramatically, and Labour was returned to power but with an overall majority reduced from 146 to just 5. There was a 2.8% national swing towards the Conservatives, who gained 90 seats. Labour called another general election in 1951, which the Conservative Party won.
The 1951 United Kingdom general election was held twenty months after the 1950 general election, which the Labour Party had won with a slim majority of just five seats. The Labour government called a snap election for Thursday 25 October 1951 in the hope of increasing its parliamentary majority. However, despite winning the popular vote and achieving both the highest-ever total vote until it was surpassed by the Conservative Party in 1992 and again in 2019 and the highest percentage vote share, Labour won fewer seats than the Conservative Party. That was caused mainly by the collapse of the Liberal vote, which enabled the Conservatives to win seats by default. The election marked the return of Winston Churchill as Prime Minister and the beginning of Labour's 13-year spell in opposition. It was the third and final general election to be held during the reign of King George VI, as he died the following year on 6 February and was succeeded by his daughter, Elizabeth II. It was the last election in which the Conservatives did better in Scotland than in England.
The 1924 United Kingdom general election was held on Wednesday 29 October 1924, as a result of the defeat of the Labour minority government, led by Prime Minister Ramsay MacDonald, in the House of Commons on a motion of no confidence. It was the third general election to be held in less than two years. Parliament was dissolved on 9 October.
The 1900 United Kingdom general election was held between 26 September and 24 October 1900, following the dissolution of Parliament on 25 September. Also referred to as the Khaki Election, it was held at a time when it was widely believed that the Second Boer War had effectively been won.
The 1885 United Kingdom general election was held from 24 November to 18 December 1885. This was the first general election after an extension of the franchise and redistribution of seats. For the first time a majority of adult males could vote and most constituencies by law returned a single member to Parliament, fulfilling one of the ideals of Chartism to provide direct single-member, single-electorate accountability. It saw the Liberals, led by William Gladstone, win the most seats, but not an overall majority. As the Irish Nationalists held the balance of power between them and the Conservatives who sat with an increasing number of allied Unionist MPs, this exacerbated divisions within the Liberals over Irish Home Rule and led to a Liberal split and another general election the following year.
The 1874 United Kingdom general election saw the incumbent Liberals, led by William Gladstone, lose decisively, even though their party won a majority of the votes cast. Benjamin Disraeli's Conservatives won the majority of seats in the House of Commons, largely because they won a number of uncontested seats. It was the first Conservative victory in a general election since 1841. Gladstone's decision to call an election surprised his colleagues, for they were aware of large sectors of discontent in their coalition. For example, the nonconformists were upset with education policies; many working-class people disliked the new trade union laws and the restrictions on drinking. The Conservatives were making gains in the middle-class, Gladstone wanted to abolish the income tax, but failed to carry his own cabinet. The result was a disaster for the Liberals, who went from 387 MPs to only 242. Conservatives jumped from 271 to 350. Gladstone himself noted: "We have been swept away in a torrent of gin and beer".
The 1865 United Kingdom general election saw the Liberals, led by Lord Palmerston, increase their large majority over the Earl of Derby's Conservatives to 80. The Whig Party changed its name to the Liberal Party between the previous election and this one.
In the 1859 United Kingdom general election returned no party to a majority of seats in the House of Commons. The Earl of Derby's Conservatives formed a minority government, but despite making overall gains, Derby's government was defeated in a confidence vote by an alliance of Palmerston's Whigs together with Peelites, Radicals and the Irish Brigade. Palmerston subsequently formed a new government from this alliance which is now considered to be the first Liberal Party administration.
In the 1857 United Kingdom general election, the Whigs, led by Lord Palmerston, won a majority in the House of Commons as the Conservative vote fell significantly. The election had been provoked by a vote of censure in Palmerston's government over his approach to the Arrow affair which led to the Second Opium War.
The 1832 United Kingdom general election, the first after the Reform Act, saw the Whigs win a large majority, with the Tories winning less than 30% of the vote.
The Representation of the People Act 1867, known as the Reform Act 1867 or the Second Reform Act, is an Act of the British Parliament that enfranchised part of the urban male working class in England and Wales for the first time. It took effect in stages over the next two years, culminating in full commencement on 1 January 1869.
The 2004 European Parliament election was the United Kingdom's part of the wider 2004 European Parliament election which was held between 10 and 13 June 2004 in the 25 member states of the European Union. The United Kingdom's part of this election was held on Thursday 10 June 2004. The election also coincided with the 2004 local elections and the London Assembly and mayoral elections. In total, 78 Members of the European Parliament were elected from the United Kingdom using proportional representation.
Multi-member constituencies existed in the Parliament of the United Kingdom and its predecessor bodies in the component parts of the United Kingdom from the earliest era of elected representation until they were abolished by the Representation of the People Act 1948. Since the 1950 general election, all members of the House of Commons have been elected from single-member constituencies.
There are five types of elections in the United Kingdom: elections to the House of Commons of the United Kingdom, elections to devolved parliaments and assemblies, local elections, mayoral elections, and police and crime commissioner elections. Within each of those categories, there may also be by-elections. Elections are held on Election Day, which is conventionally a Thursday, and under the provisions of the Dissolution and Calling of Parliament Act 2022 the timing of general elections can be held at the discretion of the prime minister during any five-year period. All other types of elections are held after fixed periods, though early elections to the devolved assemblies and parliaments can occur in certain situations. The five electoral systems used are: the single member plurality system (first-past-the-post), the multi-member plurality, the single transferable vote, the additional member system, and the supplementary vote.
The 1885 general election in Ireland was the first election following the Representation of the People Act 1884 and the Redistribution of Seats Act 1885, which redrew the Irish electoral landscape.
