In the [[United Kingdom]], [[general election]]s occur at least every five years. About 650 constituencies return a [[Member of Parliament (United Kingdom)|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.
{{TOC limit|3}}

==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 pact]]s 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 (Scotland)|Unionist Party]] and the [[National Liberal Party (UK, 1931)|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 (Northern Ireland)|Nationalist Party]], the SDLP and Sinn Féin have been major parties for the nationalist bloc.
*'''Third party''' – In England, since [[1922 United Kingdom general election|1922]], the "third party" has been the [[Liberal Party (UK)|Liberal]] party through its Alliance with the SDP and their successors up to the present day [[Liberal Democrats (UK)|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.

===Largest increase in percentage share of vote===

These records detail the change in the share of the vote by parties when compared to the same constituency in the previous general election. In some cases, such as Brent East in 2005 for the Liberal Democrats, the figures should be framed by the context of a [[by-election]] in that constituency between the two elections.

===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.<ref>{{Cite web|url=https://democracyclub.org.uk/blog/2024/06/08/2024-uk-general-election-candidate-summary/|title=2024 UK general election candidate summary|date=12 June 2024|website=democracyclub.org.uk|access-date=16 June 2024|archive-date=9 June 2024|archive-url=https://web.archive.org/web/20240609232037/https://democracyclub.org.uk/blog/2024/06/08/2024-uk-general-election-candidate-summary/|url-status=live}}</ref>

Before 1983, the consecutive records were 6 candidates in [[Paddington North (UK Parliament constituency)|Paddington North]] in 1918,<ref>{{cite book|last1=Craig|first1=F. W.

===Fewest candidates===
The general election with the fewest candidates was 1931, where only 1,292 candidates stood – with the [[National Government (United Kingdom)|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.<ref>{{cite web|url=https://commonslibrary.parliament.uk/research-briefings/cbp-7529/|title=UK Election Statistics: 1918-2023: A century of elections|date=9 August 2023|accessdate=5 July 2024|publisher=House of Commons Library}}</ref>

The last four seats to be uncontested at a general election were [[Armagh (UK Parliament constituency)|Armagh]], [[Londonderry (UK Parliament constituency)|Londonderry]], [[North Antrim (UK Parliament constituency)|North Antrim]] and [[South Antrim (UK Parliament constituency)|South Antrim]], at the [[1951 United Kingdom general election|1951 general election]].

[[Buckingham (UK Parliament constituency)|Buckingham]] was the only seat contested by only three candidates at the [[2015 United Kingdom general election|2015 general election]]. Traditionally, the [[Speaker of the House of Commons (United Kingdom)|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 of England and Wales|Green Party]] and from [[UK Independence Party|UKIP]]. However, in the [[2017 United Kingdom general election]], there were 21 seats with only three candidates and in [[2019 United Kingdom general election|2019]] there were 20. At the 2024 general election, there were no seats with fewer than five candidates.<ref>{{Cite web|url=https://democracyclub.org.uk/blog/2024/06/08/2024-uk-general-election-candidate-summary/|title=2024 UK general election candidate summary|date=12 June 2024|website=democracyclub.org.uk|access-date=16 June 2024|archive-date=9 June 2024|archive-url=https://web.archive.org/web/20240609232037/https://democracyclub.org.uk/blog/2024/06/08/2024-uk-general-election-candidate-summary/|url-status=live}}</ref>

:<sup>1</sup> 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.
:<sup>2</sup> Exact birth date not known but Fleming, who was brought up as an adopted orphan, is usually stated to have been born in 1747.
:<sup>3</sup> Exact birthdate not known but Cameron is normally stated to have been born in 1825 and was reportedly this age at election.
:<sup>4</sup> Exact birthdate not known but Walker is normally stated to have born in 1874 and was reportedly this age at election.
:<sup>5</sup> 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.

:<sup>1</sup> 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.
:<sup>2</sup> 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.

==== Returning to the house after a gap ====
A contender for the longest gap prior to returning at a general election was possibly [[Henry Drummond (1786–1860)]], who returned to the House of Commons in the [[1847 United Kingdom general election|1847 general election]] as member for [[West Surrey (UK Parliament constituency)|West Surrey]], after a near 35-year absence, though aged only 60. He was previously MP for [[Plympton Erle (UK Parliament constituency)|Plympton Erle]] from 1810 to 1812.

Others, who returned at older ages than Drummond's:

However, [[Methodist]]s took communion at Anglican churches until 1795, and some continued to do so, and many [[Presbyterian]]s were prepared to accept Anglican communion, thus ensuring that members of these creeds were represented in the Parliament.<ref>Chris Pond, [http://www.parliament.uk/commons/lib/research/notes/snpc-01493.pdf Parliament and Religious Disabilities] {{webarchive |url=https://web.archive.org/web/20070928094928/http://www.parliament.uk/commons/lib/research/notes/snpc-01493.pdf |date=28 September 2007 }}</ref> Some [[Unitarianism|Unitarians]] were also elected.

===General elections losers awarded seats on disqualification of winner===
[[Robert Grosvenor, 5th Duke of Westminster|Lord Robert Grosvenor]]: [[Fermanagh and South Tyrone (UK Parliament constituency)|Fermanagh and South Tyrone]], 1955

=== 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.

* ''Italics'' indicates constituency was newly created at that election
* '''Bold''' indicates the candidate who won that constituency's seat at that election
* An asterisk marks the MP who was incumbent in that seat, where that seat was not newly created.

===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 United Kingdom general election|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 United Kingdom general election|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 (UK Parliament constituency)|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.

''Italics'' indicates seat was regained after having been lost in a previous by-election

=== 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.<br>
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.

''Italics'' indicates seat was previously lost at a by-election and not regained by the incoming government at a general election

:<sup>1</sup> sitting member had defected from UUP to DUP
:<sup>2</sup> Liberal Democrats had won a by-election in predecessor constituency in which Labour finished second
:<sup>3</sup> by-election gain confirmed at general election.

===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 (UK)|Social Democratic Party]] and [[Liberal Party (UK)|Liberal Party]] formed the [[Liberal Democrats (UK)|Liberal Democrats]], or the [[Vanguard Unionist Progressive Party]] merged into the [[Ulster Unionist Party]].

=== Miscellaneous notable results ===
====Party wipeouts====
Elections at which a party represented in Commons stood candidates but [[Wipeout (elections)|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)<sup>S</sup>, Workers' Party (1 seat)<sup>B</sup>
* 2019: The Independent Group for Change (5 seats)<sup>S</sup>
* 2017: SDLP (3 seats), UUP (2 seats), UKIP (1 seat)
* 2015: Alliance (1 seat), Respect (1 seat)<sup>B</sup>
* 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)<sup>S</sup>
* 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)<sup>S</sup>

:<sup>S</sup>: Formed by a party split over the course of that parliament.
:<sup>B</sup>: 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 (UK)|The Independents]] (2 MPs in 2019), [[Social Democratic Party (UK, 1988–1990)#The end|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.
