Churchill left the premiership in 1955 but remained an MP until 1964. He continued through further elections instead of immediately leaving Parliament. The discussion treats that persistence as a form of public service. It also argues that an experienced former leader could advise later prime ministers, including those from another party, without seeking the leadership again. Eden's much quicker departure is used as a comparison.
