Labour and Co-operative Party

Labour and Co-operative Party (often abbreviated to Labour Co-op; Welsh: Llafur a'r Blaid Gydweithredol) is a description used by candidates in United Kingdom elections who stand on behalf of both the Labour Party and the Co-operative Party.

Candidates contest elections under an electoral alliance between the two parties, which was first agreed in 1927. This agreement recognises the independence of the two parties and commits them not to stand against each other in elections. It also sets out the procedures for both parties to select joint candidates and collaborate at a local and national level.

There were 43 Labour and Co-operative Party MPs elected at the July 2024 election, making it both the largest number of MPs ever elected under the Labour Co-op banner, and the fourth largest political grouping in the House of Commons, although Labour and Co-operative MPs are generally included in Labour totals. The chair of the Co-operative Parliamentary Group is Preet Kaur Gill; its vice-chair is Ruth Hall. On 20 July 2026, Andy Burnham became the first Labour Co-op prime minister following his leadership victory.
