Who is the last surviving member of the 1951–55 government of Winston Churchill?

Peter Alexander Rupert Carington, 6th Baron Carrington, KG, GCMG, CH, MC, PC, DL (born 6 June 1919) is a British Conservative politician who served as Defence Secretary between 1970 and 1974, Foreign Secretary between 1979 and 1982, chairman of General Electric between 1983 and 1984, and Secretary General of NATO from 1984 to 1988. He is the last surviving member of the 1951–55 government of Winston Churchill, the Eden government, and the Macmillan government and of the cabinets of Alec Douglas-Home and Edward Heath. Following the House of Lords Act 1999, which removed the automatic right of hereditary peers to sit in the House of Lords, Carrington was created a life peer as Baron Carington of Upton, of Upton in the County of Nottinghamshire.

Carington was Foreign Secretary in 1982 when the Falkland Islands were invaded by Argentina. He took full responsibility for the failure of the Foreign and Commonwealth Office to foresee this and resigned. As Secretary General of NATO, he helped prevent a war between Greece and Turkey in 1987.
