Socialist Appeal was the British section of the International Marxist Tendency (IMT), founded in 1992 alongside the IMT by supporters of Ted Grant and Alan Woods after they were expelled from the Militant tendency of the Labour Party. The organisation relaunched itself in 2024 as the Revolutionary Communist Party.

Edward Grant was a South African Trotskyist who spent most of his adult life in Britain. He was a founding member of the group Militant and later Socialist Appeal.
