Socialist Campaign Group

The Socialist Campaign Group (Welsh: Grŵp Ymgyrch Sosialaidd), also simply known as the Campaign Group, is a UK parliamentary caucus of the Labour Party including Members of Parliament in the House of Commons.

The group was formed in 1982 following the 1981 Labour Party deputy leadership election when a number of soft left MPs, led by Neil Kinnock, refused to back Tony Benn's campaign, leading a number of left-wing Benn-supporting MPs to split from the Tribune Group to form the Campaign Group. It was at a meeting of the Campaign Group in 2015 that the decision was taken that Jeremy Corbyn would contest for the leadership of the Labour Party. The Campaign Group maintains close links with Momentum.
