Biography | Murphy joined the Socialist Labour Party (SLP) in 1916 and stood as a candidate in the 1918 General Election for the Gorton constituency in Manchester. He then participated in the communist unity discussions, and as a result split from the SLP, joining the Communist Party of Great Britain at its formation in 1920. He was a member of the Central Committee until he was expelled from the party in 1932. He was active in the National Minority Movement, a Communist-led united front within the trade unions, from its formation in 1924. In 1925 Murphy was one of twelve CPGB officials imprisoned for seditious libel and incitement to mutiny. |
