Harry Pollitt was a British communist who served as the General Secretary of the Communist Party of Great Britain from 1929 to September 1939 and again from 1941 until his death in 1960. Pollitt spent most of his life advocating communism. Ideologically a Marx-Leninist, Pollitt was an adherent particularly of Joseph Stalin even after Stalin's death and disavowal by Khrushchev. Pollitt's acts included opposition to the Allied intervention in the Russian civil war, support for the Spanish republicans during the Spanish civil war, both support and opposition to the war against Nazi Germany, defence of the communist coup in Czechoslovakia, and criticism of British colonialism.
He contested a number of parliamentary elections, but never won, despite coming close in 1945. Throughout his time as leader of CPGB, he was in direct secret radio contact with Moscow as CPGB's "Code Holder", and was spied on by the British security services.
