Gaitskellism
Wilson went on to become Prime Minister in the 1964 election, holding the position from 1964 to 1970 and from 1974 to 1976. Despite being a former Bevanite, Wilson largely followed Gaitskellite economic policies, and the former Gaitskellite Callaghan followed Wilson as Prime Minister from 1976 to 1979 and Party Leader from 1976 to 1980.
Barbara Castle
Labour returned to government under Harold Wilson in October 1964 following a general election, defeating Alec Douglas-Home's Conservative government by winning a slim majority of four seats, thus ending 13 years of successive Conservative governments. Wilson had selected his core Cabinet four months prior to the election; Castle knew Wilson intended to place her within his Cabinet, which would make her the fourth woman in British history ever to hold position in a Cabinet, after Margaret Bondfield, Ellen Wilkinson and Florence Horsbrugh.
