Ellis Simon Hillman (17 November 1928 – 21 January 1996)[citation needed] was a British Labour politician, local councillor, Mayor of the London Borough of Barnet (1994–95) and polytechnic history lecturer.
He became a critical member of the Socialist Review Group where he produced a document, The Nature of the Stalinist Parties, which was rejected by the group and replied to by Duncan Hallas.[3][4] This followed by a further document, On Organic Unity, where he advocated the group fuse with that of Ted Grant, which led to his expulsion.[3][5]
Hillman then joined Gerry Healy's Club; however, he became a secret sympathiser of the Revolutionary Socialist League.[1] Hillman went on to become the RSL's treasurer[6] and a founder member of the Militant editorial board.[7][1] In 1961, whilst a member of the RSL, Hillman wrote a guide for members who were elected to councils: Notes on Council Work.[6]
Hillman was elected to Barnet council in 1986 and when in 1994 it fell to a Lib–Lab alliance he was elected Mayor.[8] His first act was to remove a bust of Margaret Thatcher from Hendon Town Hall.[1][8]
