and Lord Wilmington ( 1673–1743) lived under the reigns of the same seven sovereigns: Charles II, James II, joint sovereigns William III and Mary II, Queen Anne, George I, and George II. Winston Churchill (1874–1965), Clement Attlee (1883–1967), Anthony Eden (1897–1977) and Harold Macmillan (1894–1986) all lived under the reigns of the same six sovereigns: Victoria, Edward VII, George V, Edward VIII, George VI and Elizabeth II. Time between the start or end of a monarch's reign and the appointment of a prime minister The record for the prime minister appointed latest into a monarch's reign is held by Liz Truss, who was appointed 70 years and 7 months into the reign of Elizabeth II. She also holds the record for the prime minister appointed closest to the end of a monarch's reign, being appointed two days before the death of Elizabeth II. The record for the prime minister appointed soonest into the reign of a monarch goes to Rishi Sunak, the immediate successor of Liz Truss, appointed 47 days into the reign of Charles III. These records all come about largely due to (but are not inherently dependent on) the unique circumstance of the end of Elizabeth II's record-breaking long reign coinciding with the start of Liz Truss' record-breaking short term. Various other records can be derived from these facts, such as the shortest time between the end of a prime minister's term and end of a monarch's reign being the 2 days between the resignation of Boris Johnson and death of Elizabeth II, or the shortest time between the start of a monarch's reign and end of a prime minister's term being the 47 days between the ascension of Charles III and the resignation of Liz Truss. Age Age at appointment The youngest prime minister to be appointed was William Pitt the Younger on 19 December 1783 at the age of 24 years and 208 days. The oldest prime minister to be appointed for the first time was Lord Palmerston on 6 February 1855 at the age of 70 years and 109 days. The oldest prime minister to be appointed overall, and oldest to win a General Election, was William Ewart Gladstone, who was born on 29 December 1809 and appointed for the final time on 15 August 1892 at the age of 82 years and 231 days, following that year's General Election.
