The RCG argues that socialists should not give their support to the centre/centre-left Labour Party, which is one of the major political parties in the United Kingdom. On this subject, David Yaffe stated the RCG's position that "no anti-imperialist or socialist movement can be built unless the British left makes a fundamental and irrevocable break with the British Labour Party." He went on to characterise the party's policies in government as being "openly racist, imperialist and warmongering". At the same time it has remained critical of other socialist organisations in Britain such as the Communist Party of Great Britain, Militant, the International Marxist Group and the Socialist Workers Party for what it sees as being "major obstacle" to the building of an anti-imperialist movement in Britain. This is because many of these groups denounced the governments of socialist states such as the Soviet Union, China and Cuba, and instead encouraged their members to vote for the Labour Party.
