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
Castle lost her place as a Cabinet minister when her bitter political enemy James Callaghan succeeded Wilson as Prime Minister following a leadership election. Although he left Wilson's Cabinet virtually unchanged, he dismissed Castle almost immediately upon taking office. Callaghan removed her under the pretext he wanted to lower the average age of his Cabinet, which she regarded as a "phoney reason". In an interview years later, she remarked that perhaps the most restrained thing she had ever achieved in her life was not to reply with "Then why not start with yourself, Jim?" (Callaghan was four years older than Wilson, the man he was replacing).
