Committee to Defeat Revisionism, for Communist Unity

British Marxist–Leninist group
Committee to Defeat Revisionism, for Communist Unity was a small British Marxist–Leninist group that left the Communist Party of Great Britain in 1963. CDRCU was led by Michael McCreery, the son of General Sir Richard McCreery. CDRCU was sympathetic towards the Chinese Communist Party and the Party of Labour of Albania, with CDRCU members attending May Day celebrations in Tirana in May 1964. The group began publishing Vanguard in 1963.

CDRCU reached the height of its activity from February 1964 to February 1965, during which CDRCU cells were established in London, the Thames Valley, Scotland, West Yorkshire, Manchester and Cardiff, and public meetings were arranged. CDRCU had split with other CPGB members, some of them based around the Forum publication, who wanted to remain inside the CPGB to conduct the anti revisionist struggle. In October 1964, the CDRCU stood a candidate in Huyton in the general election, gaining 899 votes. After McCreery died (at the age of only 36) from cancer in 1965 in New Zealand, the activity of the group declined sharply. Most of the members of CDRCU regrouped into the Action Centre for Marxist Leninist Unity, which evolved into the Marxist Leninist Organisation of Britain. A small number formed the Finsbury Communist Association. Others later formed the Workers' Party of Scotland and the London Workers' Committee. In 1966 the London Workers' Committee split, becoming the
Working People's Party of England. Noel Jenkinson, a Protestant from Meath, was another Ireland born member of CDRCU who had joined from the Communist Party of Great Britain. Vanguard continued publication until 1972.
