• Of the 24 former prime ministers who have served since 1902, half (12) received a peerage entitling membership of the House of Lords after departing the House of Commons.
  • Of the 12 former prime ministers to have received a peerage, seven received a hereditary earldom. Harold Macmillan, who served as prime minister between 1957 and 1963, was the last former prime minister to receive an earldom. He became the Earl of Stockton in 1984. Since 1999, a hereditary earldom has not automatically entitled the bearer to a seat in the House of Lords.
  • The remaining five received life peerages under the Life Peerages Act 1958. Sir Alec Douglas-Home, who served as prime minister between 1963 and 1964, was the first former prime minister to receive a life peerage. He was created Lord Home of the Hirsel in 1974, having disclaimed a hereditary earldom previously.
  • The most recent former prime minister to receive a peerage is David Cameron. Prime Minister Rishi Sunak appointed Mr Cameron foreign secretary in 2023. His peerage title is Lord Cameron of Chipping Norton. Lord Cameron left the House of Commons in 2016.
  • The second most recent former prime minister to receive a peerage was Margaret Thatcher. Her life peerage was conferred in 1992, after which she was known as Baroness Thatcher.
  • Two former prime ministers, Theresa May and Elizabeth Truss, remain MPs.
