2024 United Kingdom general election in Northern Ireland

The 2024 general election in Northern Ireland was held on 4 July 2024, with all 18 Northern Irish seats in the House of Commons contested. The general election occurred after the recently completed constituency boundaries review.
MPs are elected in 18 single-member constituencies by first-past-the-post.
On 22 May 2024, Prime Minister Rishi Sunak announced 4 July 2024 as the election date.
In June 2023, it was published that The Boundary Commission for Northern Ireland had made final recommendations for the new boundaries for Northern Ireland's 18 parliamentary constituencies. The report was submitted to the speaker of the UK House of Commons and the UK Government was required to submit a draft of an Order in Council to activate the new boundaries within four months. Changes include:
Ten wards were moved and as approved by MPs, the new boundaries became effective on 1 November 2023. These changes were approved at a meeting of the Privy Council on 15 November and came into force on 29 November.
In the run up to the election, there was speculation to the extent at which unionist electoral pacts would be active in some constituencies. In July 2023, Ulster Unionist Party (UUP) leader Doug Beattie clarified that his party intends to stand candidates in 17 constituencies, but there was still speculation about whether the Traditional Unionist Voice (TUV) would field candidates. The TUV leader Jim Allister said that in seats held by non-unionists where the sitting MP could potentially be ousted, it would support an "agreed single unionist candidate".
In North Down, there were calls for unionist parties to drop their own candidates and unite behind a single contender to defeat incumbent Alliance MP Stephen Farry. Farry was confirmed as Alliance's candidate for North Down at the next election on 26 November 2023. On 24 January 2024, the UUP selected former Iraq War veteran Tim Collins as their candidate for North Down, with the UUP leader Doug Beattie saying his party "does not do pacts". Alex Easton announced his independent Unionist candidacy for the seat.
In October 2023 the Alliance Party of Northern Ireland revealed that they intended to target Lagan Valley, seat of the then-leader of the Democratic Unionist Party (DUP) Jeffrey Donaldson. They unveiled their candidate as Sorcha Eastwood and required a 7.16% swing to gain the seat from the DUP.
Amongst majority nationalist constituencies, due to their strong performance in the 2022 Assembly election and the 2023 local elections, Sinn Féin look "likely to increase its number of seats at Westminster", with the possibility of gaining Social Democratic and Labour Party (SDLP) leader Colum Eastwood's seat of Foyle.
The campaign got underway in South Belfast and North Down, with both incumbent MPs, Claire Hanna and Stephen Farry seeking re-election. North Down Ulster Unionist candidate Tim Collins said he was "very confident" of unseating Farry.
In January 2024, the Ulster Unionist Party selected their former leader and Minister of Health Robin Swann as their candidate for South Antrim and announced their deputy leader, Robbie Butler, as the party's candidate for Lagan Valley.
On 16 March 2024, the Traditional Unionist Voice formed an electoral pact with Reform UK, in which the two parties would stand mutually agreed candidates within Northern Ireland. On 24 May they announced that they were supporting Alex Easton, the Independent Unionist candidate in North Down, and would not stand a candidate in that constituency.
The leader of the Green Party Northern Ireland, Sen. Mal O'Hara, told Slugger O'Toole on 26 April 2024 that they would stand in every constituency and would not pursue any electoral pacts.
On 7 May 2024, the UUP announced that 19 year-old Jay Basra, who is Punjabi-British, would be their candidate for Mid Ulster. Following the announcement, Basra was the target of racial abuse on social media. The abuse was condemned by UUP leader Doug Beattie and former First Minister Arlene Foster, as well as deputy First Minister Emma Little-Pengelly.
Jeffrey Donaldson, who was the DUP leader until March 2024, appeared in court on 3 July to face additional sex offence charges.

Sinn Féin became the largest Northern Ireland party in the House of Commons for the first time, following similar success in the 2022 Assembly election and 2023 local election. Sinn Féin defended their seven seats with an increased majority in each, South Down, Belfast North and especially Fermanagh and South Tyrone are less marginal than they were in 2019. Sinn Féin also came very close to gaining East Londonderry, Kathleen McGurk was the runner-up just 179 votes behind the DUP. Sinn Féin also narrowed the SDLP's majority in Foyle.
The DUP won five seats, three less than in 2019, this was the lowest number of DUP MPs since 2001 and since the DUP became the largest unionist party. The DUP lost Lagan Valley to Alliance, South Antrim to the UUP and North Antrim to the TUV. The loss of North Antrim by just 450 votes is particularly notable, the DUP had held this seat for its entire existence, and between them Ian Paisley and Ian Paisley Jr had represented this constituency for 54 years since 1970. The majorities of Sammy Wilson in East Antrim and especially Gregory Campbell in East Londonderry, were significantly reduced, both were narrowly held against challenges from Alliance by 1,306 votes and Sinn Féin by 179 votes respectively. A more positive result for the DUP was the re-election of new leader Gavin Robinson in Belfast East with a slightly increased majority, the DUP also held Strangford and Upper Bann.
The SDLP held their two seats. In Foyle SDLP leader Colum Eastwood's majority was reduced from 17,110 to 4,166, mainly due to lower turnout although there was a swing to Sinn Féin. Claire Hanna was also re-elected to the new Belfast South and Mid Down constituency with a slightly reduced majority of 12,506, this is now the fifth safest seat in Northern Ireland after Sinn Féin's four safest seats. Outside of these two constituencies the SDLP vote mainly decreased, with Belfast West a notable exception. The SDLP was the runner-up in South Down and Newry and Armagh, both were previously SDLP held seats but are increasingly safe for Sinn Féin.
Alliance remains the third largest party in Northern Ireland in terms of vote share, as it was in the 2022 Assembly election and 2023 local election. Alliance gained Lagan Valley from the DUP, with Sorcha Eastwood becoming the third directly elected Alliance MP. Alliance also lost North Down, with independent unionist Alex Easton gaining from Alliance deputy leader Stephen Farry, the party leader Naomi Long also lost in Belfast East, Long was the previous MP for Belfast East from 2010 to 2015. Alliance came a particularly close second in East Antrim, and was also runner-up in Strangford and in Belfast South and Mid Down for the first time since 1987. In other constituencies the Alliance vote was generally down slightly from their peak in 2019, but higher than any previous elections.
The UUP gained a seat in the House of Commons for the first time since 2015, with the election of Robin Swann in South Antrim, Swann achieved the highest majority in South Antrim since 1997 (7,512). The UUP was runner-up in one other constituency, Fermanagh and South Tyrone, which the party had last won in 2015, although Diana Armstrong was the sole unionist candidate the increase in the Sinn Féin vote ensured the seat remained a Sinn Féin hold. As with Alliance, the UUP's second best prospect in this election was East Antrim, fewer than 2,000 votes separated the top three candidates.
The TUV gained a seat in the House of Commons for the first time, with Jim Allister gaining North Antrim from the DUP by 450 votes. Beyond North Antrim the TUV's strongest constituencies were East Londonderry, East Antrim and Strangford. The other MP elected in Northern Ireland was independent unionist Alex Easton in North Down who gained the seat from Alliance, Easton left the DUP in 2021 and he is the fourth North Down MP to have been elected either as an independent or with a smaller unionist party after leaving the DUP or UUP.
