Labour and Co-operative Party (often abbreviated 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, that was first agreed in 1927. This agreement recognises the independence of the two parties and commits them to not standing against each other in elections. It also sets out the procedures for both parties to select joint candidates and interact at a local and national level.
