# United Kingdom general election records

This short description is INTENTIONALLY "none" &#x2D; please see WP:SDNONE before you consider changing it!
In the United Kingdom, general elections occur at least every five years. About 650 constituencies return a member of Parliament. Prior to 1945, electoral competition in the United Kingdom exhibited features which make meaningful comparisons with modern results difficult. Hence, unless otherwise stated, records are based on results since the 1945 general election, and earlier exceptional results are listed separately.

## Glossary

For comparison purposes the following definitions have been adopted.
* Gain – victory by a party which was not victorious at the immediate previous election.
* Loss – defeat of a party which was victorious at the immediate previous election.
* Hold – victory by a party which was victorious at the immediate previous election.
* Win – victory by a party. Ambiguous term that could mean either a gain or a hold.
* Incumbent – the party which held the seat at the immediate previous election, irrespective of any intervening change of candidate or candidate's change of party.
* Major party – A party that has a realistic chance of leading government. Since 1945, every UK government has been led by the Conservatives or Labour. Parties in electoral pacts whose members take the whip of a major party and have no de facto independence are also counted as part of the major parties. For Labour, this includes the Co-operative Party. For the Conservatives, this includes the Unionist Party and the National Liberal Party. In Northern Ireland the situation is more fluid, but both the UUP and the DUP have been major parties for the unionist bloc and the Nationalist Party, the SDLP and Sinn Féin have been major parties for the nationalist bloc.
* Third party – In England, since 1922, the "third party" has been the Liberal party through its Alliance with the SDP and their successors up to the present day Liberal Democrats. Additionally, in Scotland and Wales the Scottish National Party and Plaid Cymru are also considered to be third parties. Prior to 1922, the third party was the Labour party.
* Minor party – parties smaller than the third party. In Northern Ireland, where the party landscape is unstable and many apparently independent candidates are supported by other parties, "minor party" refers to parties and independents that are not members of the main nationalist or unionist blocs.
* Uncontested – an election where only one candidate is put forward. No votes are actually cast and the candidate is by default the victor.
* Notional – boundary changes occur about every 10–15 years. The political composition of many seats is changed as a result, sometimes decisively. Professors Colin Rallings and Michael Thrasher have compiled notional results for the last few sets of boundary changes, predicting what the result would have been at the previous election under the new boundaries.

### Largest fall in percentage share of vote

A party's share of the vote at a general election is not always matched at subsequent general elections, but given the five-year maximum term of a Parliament since 1911, reductions of 10% or more (on the national level) or around 30% or more (in individual constituencies) are unusual.

#### Candidates winning fewer than ten votes

Candidates in general elections since 1918 who won fewer than ten votes:
| Votes | Candidate | Party | Constituency | Election |
| 1 | Catherine Taylor-Dawson | Vote For Yourself Rainbow Dream Ticket | Cardiff North | 2005 |
| 3 | Bobby Smith | Give Me Back Elmo | Maidenhead | 2017 |
| 5 | Martin Kyslun | Independent | West Derbyshire | 2005 |

Both W. M. Somerville and John Magee in Drogheda at the 1852 United Kingdom general election received no votes and George Griffith in Bewdley at the 1874 United Kingdom general election received one vote. However, in the pre-secret ballot era, some candidates stood at the hustings but for various reasons did not contest the poll, and hence could be recorded with no or few votes although in effect they were not standing. Examples include George J. Harney at Tiverton at the 1847 United Kingdom general election (no votes), William Johnston in Downpatrick at the 1857 United Kingdom general election (one vote), Humphrey Brown at the 1859 Tewkesbury by-election (no votes) and Dr Frederick R. Lees at the 1860 Ripon by-election (no votes).

### Most candidates

Any number of candidates can be nominated for election under current UK electoral law. The only restrictions are that a candidate must be a Commonwealth or Irish citizen, not legally disqualified, with the valid nomination of ten electors from the constituency. Candidates must pay a £500 deposit which is only refunded if the candidate wins 5% or more of the votes cast.
The election with the largest number of candidates was the 2024 general election, with 4,515.
There have been 24 occasions when there were more than ten candidates on a single ballot in a general election. Large numbers of candidates are common in London seats and in the seat of the incumbent Prime Minister (marked in bold in the below list).
| Candidates | Constituency | Election | Incumbent |

### Fewest candidates

The general election with the fewest candidates was 1931, where only 1,292 candidates stood – with the National Government, the major parties did not stand against each other in many seats. Since 1945, the election with the fewest candidates is 1951, with 1,376.
The last four seats to be uncontested at a general election were Armagh, Londonderry, North Antrim and South Antrim, at the 1951 general election. The last seats in Great Britain to be uncontested were Liverpool Scotland and Rhondda West, at the 1945 general election.
Three seats were contested only by Labour and Conservative candidates at the 1979 general election: Birmingham Handsworth, Dudley West and Salford East.
Buckingham was the only seat contested by only three candidates at the 2015 general election. Traditionally, the Speaker of the House of Commons is not opposed by major parties, so the only opposition to John Bercow was candidates from the Green Party and from UKIP. However, in the 2017 United Kingdom general election, there were 21 seats with only three candidates and in 2019 there were 20. At the 2024 general election, there were no seats with fewer than five candidates.

    $^1$ Exact birth date not known but Harrison was reportedly this age when he died 5 days after the general election closed and before he took his seat.
    $^2$ Exact birth date not known but Fleming, who was brought up as an adopted orphan, is usually stated to have been born in 1747.
    $^3$ Exact birthdate not known but Cameron is normally stated to have been born in 1825 and was reportedly this age at election.
    $^4$ Exact birthdate not known but Walker is normally stated to have been born in 1874 and was reportedly this age at election.
    $^5$ Khabra's exact age has been the subject of some disagreement. He claimed a birth year of 1924, which would have made him 67 years old at first election, but his marriage certificate gives a birth year of 1921, and it is this figure which has been used above.

    $^1$ Davies was suspected of being considerably older than he claimed. There is evidence to suggest he was born in 1879, not 1886; if true, this would indicate he was 90 at his last election.
    $^2$ Keene's birthdate is given as "c. 1731" in reference works though he was reportedly 90 years old on his death in February 1822. On this the figure is based. Unopposed return, his last contested election was in 1802 when aged 70–71.
    Note: All men aged 79 or over since 1945 and over 85 since 1900 are listed, as are all women aged 70 or over.

However, Methodists took communion at Anglican churches until 1795, and some continued to do so, and many Presbyterians were prepared to accept Anglican communion, thus ensuring that members of these creeds were represented in the Parliament. Some Unitarians were also elected.
The first Roman Catholic general election victors in the UK Parliament were at the 1830 general election. They included Daniel O'Connell and James Patrick Mahon in Clare.
The first Quaker general election victor was Edward Pease at the 1832 general election.
The first Moravian general election victor was Charles Hindley at the 1835 general election.
Lionel de Rothschild was the first Jewish general election victor at the 1847 general election. He was not permitted to take his seat until the passage of the Jews Relief Act 1858.
The first Catholic Apostolic general election victor was Henry Drummond also at the 1847 election.
The first Baptist general election victor was George Goodman at the 1852 general election.
The first Congregationalist general election victor was Samuel Morley at the 1865 general election.
The first declared atheist to win a general election was Charles Bradlaugh at the 1880 general election. He was not permitted to take his seat in that parliament, but was elected again at the 1885 general election and allowed to take the oath.
Dadabhai Naoroji was the first Parsi general election victor at the 1892 general election.
Piara Khabra became the first Sikh general election victor at the 1992 general election.
Terry Rooney became the first Mormon general election victor at the 1992 general election (previously taking his seat at a by-election in 1990).
The first Muslim general election victor was Mohammed Sarwar at the 1997 general election.
The first Hindu general election victor was Shailesh Vara at the 2005 general election.
The first Buddhist general election victor was Suella Braverman as Suella Fernandes at the 2015 general election.

### Two or more sitting MPs contest general election

It is of course common for former (defeated) MPs to seek re-election, often in their old constituencies, especially if they are marginal or bellwether seats. What is quite unusual is for two MPs both sitting in the same parliament to seek re-election in the same seat. This usually occurs by reason of boundary changes or party splits.

### Election days

Currently, all British Parliamentary elections are invariably held on a Thursday. The last general election not held on a Thursday was the 1931 election, which was held on Tuesday 27 October. Prior to this, it was common to hold general elections on any day of the week (other than Sunday), and until the 1918 general election, polling (and the declaration of results) was held over a period of several weeks.

#### Suspended elections

On rare occasions, polling in an individual constituency may be suspended, usually as a result of the death of a candidate. The last occasion was at Thirsk and Malton in 2010, where polling was delayed for three weeks owing to the death of the UKIP candidate.

### Outgoing Government gains seats

When there is a decisive change in electoral sentiment, a tiny number of seats will not only buck the trend by not moving as expected, but may actually move in the opposite direction. Only elections that saw a change of government are listed, since it is fairly common for a few seats to move in divergent directions when an incumbent government is re-elected; 2005 was an exception to this case, when the Labour party scored no gains.

### Incoming Government loses seats

Notes: In 2010 the Conservatives entered government as the largest party in a coalition and in 2015 they went from being part of a coalition to being a majority government in their own right. In 2017 the Conservatives entered government without an overall majority and in 2019 they went from having a minority government to being a majority government in their own right.
In 2010 the Liberal Democrats entered government as a junior partner in a coalition.

### General election victors had not contested previous election

It is unusual for a party that had not contested the seat at the previous election to win it. Since the major mainland parties now routinely contest all seats, except the Speaker's, such rare victories tend to come from independents or splinter-parties.

### Incumbent party did not contest

The rare occasions where the party which won the previous election did not contest the seat. Independent candidates are not included, nor Speakers of the House of Commons. Cases where candidates were suspended from their parties after nominations closed (meaning they still appeared on the ballot under the name of their former party) are also not counted. Also excluded are occasions where the party had merged into an organisation which did contest the election, such as when the Social Democratic Party and Liberal Party formed the Liberal Democrats, or the Vanguard Unionist Progressive Party merged into the Ulster Unionist Party.
| Election | Constituency | Incumbent party | Notes |
| 1997 | North Down | UPUP | Sole UPUP MP had died and party had subsequently collapsed. The UK Unionist Party had won the 1995 by-election, meaning the UPUP were no longer incumbents in 1997. |
| 1983 | Mid Ulster | UUUP | UUUP had dissolved and former MP stood down. |
| 1974 February | Belfast West | Republican Labour | MP had defected to the Social Democratic and Labour Party and RLP had dissolved. |
| 1959 | Caithness and Sutherland | Unionist | Stood aside for Independent Unionist David Robertson. |
| 1955 | Fermanagh and Tyrone | Nationalist | Stood aside for Sinn Féin candidate. |
| 1950 | Chelmsford | Common Wealth | MP had defected to Labour and party decided not to contest any further elections. |
| 1950 | Glasgow Camlachie | Ind. Labour Party | MP had defected to Labour, then the ILP had performed badly in the 1948 by-election. |

### Miscellaneous notable results
#### Party wipeouts

Elections at which a party represented in Commons stood candidates but lost all of its seats. Parties that did not run any candidates, or whose MPs had all left and joined other parties prior to the election, are not counted.
* 2024: Alba (2 seats)$^S$, Workers' Party (1 seat)$^B$
* 2019: The Independent Group for Change (5 seats)$^S$
* 2017: SDLP (3 seats), UUP (2 seats), UKIP (1 seat)
* 2015: Alliance (1 seat), Respect (1 seat)$^B$
* 2010: Independent Kidderminster Hospital and Health Concern (1 seat), Respect (1 seat), UUP (1 seat)
* 2001: UK Unionist Party (1 seat)
* 1992: Sinn Féin (1 seat)
* 1979: Scottish Labour Party (2 seats)$^S$
* 1974 Oct: Democratic Labour (1 seat)
* 1974 Feb: Unity (2 seats)
* 1955: Sinn Féin (2 seats), Irish Labour (1 seat)
* 1950: Communist Party of Great Britain (2 seats), Irish Labour (1 seat)$^S$
    $^S$: Formed by a party split over the course of that parliament.
    $^B$: Seat won at a by-election, not the previous general election.
In 1997, the Conservatives saw a complete wipeout in Scotland and Wales, but won seats in England. The Welsh Liberal Democrats lost all their seats in 2015. The Welsh Conservatives once again saw a wipeout in 2024.
In some cases, party splits have led MPs to run as independents in groups that are not considered full-fledged parties. The Independents (2 MPs in 2019), Independent Social Democrats (3 MPs in 1992) and the Labour Independent Group (4 MPs in 1950) are examples of independent groupings with several members that were wiped out at general election.
