Living Prime Ministers of the United Kingdom

This is a list of all of the living people who have served as Prime Minister of the United Kingdom at each moment in British history.

There have been four time periods when there was only one living Prime Minister, first with the appointment of Sir Robert Walpole in 1721, and most recently during the second term of William Ewart Gladstone following the 1881 death of Benjamin Disraeli. There have been ten time periods when six living current or former Prime Ministers co-existed, with the longest being a nine-year period beginning with the first appointment of Sir Robert Peel in 1834. The most recent period was between 1990 and 1995 beginning with the 1990 appointment of John Major, and ending with the 1995 death of Harold Wilson. If one includes future Prime Ministers, there has been only one time period when nineteen (see § Statistics) different Prime Ministers co-existed.

There are presently five living Prime Ministers. From oldest to youngest: Sir John Major, Gordon Brown, Tony Blair, Theresa May and David Cameron.
