Militant Labour

The Socialist Party is a Trotskyist political party in England and Wales. The Socialist Party was founded in 1991 as Militant Labour, its members having previously been organised as the Militant tendency within the Labour Party. A minority of Militant supporters opposed the setting up of an independent party and remained within the Labour Party as Socialist Appeal. In 1997 the party adopted its current name, although in elections it fields candidates as Socialist Alternative, due to the right to stand under the name Socialist Party being held by the Socialist Party of Great Britain. The Socialist Party has held council seats in several areas of Britain but has never had any elected MPs, although prominent Militant supporters Dave Nellist, and the late Pat Wall and Terry Fields, were elected to parliament as Labour MPs prior to the formation of the party.

The Socialist Party is registered with the United Kingdom Electoral Commission, however, it is active only in England and Wales, with sister parties active in Scotland and Northern Ireland. The party is a member of the Committee for a Workers' International and the European Anti-Capitalist Left.
