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, in the midst of a complex health bill that she was steering through the House of Commons at the time. Although he had not yet decided on her successor at the time he fired her, 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, and less than 18 months younger than Castle). Castle was angry to discover that Wilson had broken a private confidence in informing Callaghan that she had intended to retire from the cabinet before the next election.
