The Communist League of Great Britain was an anti-revisionist group in the United Kingdom. It origins were in the Communist Party of Great Britain, where a faction formed around Bill Bland. Initially Maoist, it joined the majority of the Committee to Defeat Revisionism, for Communist Unity in 1965 to form the Action Centre for Marxist-Leninist Unity, publishing Hammer or Anvil. In 1967, this was renamed the Marxist-Leninist Organisation of Britain. Soon after, the group ceased supporting Mao, instead supporting Enver Hoxha - although Hoxha himself was aligned with Mao. Renamed the "Communist League of Great Britain" in 1975, its ideological position was strengthened with the Sino-Albanian Split.
