2024 United Kingdom general election in Wales

The 2024 United Kingdom general election was held on Thursday, 4 July 2024. Thirty-two seats were up for election in Wales as the general election occurred after the recently completed boundary review took effect. The Labour Party won a landslide victory of Welsh MPs, gaining six seats for a total of 27. Both Plaid Cymru and the Liberal Democrats gained one seat each, taking them to four seats and one seat respectively. The Conservatives lost all thirteen seats they had held previously, leaving the party without Westminster representation from Wales for the first time since 2001.

Date of the election
On 22 May 2024, Prime Minister Rishi Sunak announced 4 July 2024 as the election date.

Number of Welsh MPs
As required by the Parliamentary Voting System and Constituencies Act 2011 as amended by the Parliamentary Constituencies Act 2020, the number of seats in Wales must be reduced from 40 to 32 to more accurately reflect its share of registered voters, including one coinciding with the Isle of Anglesey. The Boundary Commission for Wales is responsible for drawing up proposals for the new constituency boundaries, but it must abide by this total.

The 2023 Periodic Review of Westminster constituencies began in 2020 and concluded in 2023. Initial proposals were published in September 2021. The revised proposals were published on 19 October 2022 followed by a four-week consultation period. On 28 June 2023, the Boundary Commission for Wales published its final recommendations for the new Welsh constituencies. These changes were approved at a meeting of the Privy Council on 15 November. and came into force on 29 November.

Analysis
The Labour Party remained the largest party in Wales, winning 27 of the 32 seats. In addition to defending all of their seats in the south including around Cardiff and Swansea, Labour reversed many of the Conservative gains in 2019, gaining seats such as Bangor Aberconwy, Clwyd East, Clwyd North, Monmouthshire and Wrexham. Labour also won in Montgomeryshire and Glyndŵr, which had been until 2024 the only area in Wales which had never elected a Labour MP.

Plaid Cymru won four seats, the same as in 2019, however given boundary changes and the reduction in seats this should be counted as two gains. Plaid Cymru defended Dwyfor Meirionnydd and Ceredigion Preseli with significant majorities, gaining the new seat of Caerfyrddin which had been nominally Conservative in 2019, and gained Ynys Môn from the Conservatives. This was the first time Plaid Cymru had won in Ynys Môn since 2001, it was the most marginal seat in Wales with a majority of 637 votes between Plaid and Conservatives, with Labour in close third place.

The Liberal Democrats gained one seat in Wales, Brecon, Radnor and Cwm Tawe. Outside of briefly holding the predecessor seat following the 2019 Brecon and Radnorshire by-election, the Liberal Democrats have not had a seat in Wales since losing Ceredigion in 2017.

The Conservative Party lost every seat in Wales, having won fourteen seats in 2019, the first time since 2001 that Wales had no Conservative MPs. This was despite the Conservatives taking 18.2% of the overall vote and outpolling both Plaid Cymru and the Liberal Democrats in terms of votes.

Reform UK was the third largest party in terms of votes with 16.9%, nearly as much votes as the Conservatives and more than both Plaid Cymru and the Liberal Democrats. Reform was the runner-up in twelve constituencies, coming closest to winning in Llanelli. The Green Party was runner-up in one constituency, Cardiff South and Penarth.
