The group increasingly moved from Maoism to anti-revisionism, and in 1997 they officially dissolved the ACW and joined the Socialist Labour Party (SLP). When many of them left the SLP in 2004, they founded the Communist Party of Great Britain (Marxist–Leninist). The CPGB-ML was the founder of the broad electoral front of the Workers Party, together with George Galloway in 2019. The organisations formally separated, however in 2021.
