The 2019 United Kingdom general election was held on 12 December 2019 to elect all 650 members of the House of Commons, including the 40 Welsh seats. Compared to the 2017 general election, the Labour Party lost six seats, each of which was won by the Conservative Party. Plaid Cymru retained its four seats. This reflected a decrease in vote share of 8% from the Labour Party, matched by increases in vote share for the Brexit Party and Conservative Party of 5.4% and 2.5%, respectively. However, the Labour Party remained the party receiving the most votes, with a 40.9% vote share. Having gained Brecon and Radnorshire in the 2019 Brecon and Radnorshire by-election earlier in the year, the Welsh Liberal Democrats lost to the Conservatives.
