Liz Truss, 44 days
The unwanted leader of the rating is unarguably Liz Truss. She was appointed as the prime minister following the resignation of Boris Johnson and formerly served as the foreign secretary. Her premiership came to its demise following a failed attempt at the UK budget amendments known as “mini-budget” which largely resorted to unfunded tax cuts.
Liz Truss’ tenure is shorter by more than 300 days than the next in the rating, Sir Alec Douglas-Home.

Sir Alec Douglas-Home, 363 days
Being a Conservative party member, he lost his premier position after the 1964 UK General election, where Labour won by a narrow margin. It should be noted – he was also the Secretary of State for Foreign and Commonwealth Affairs before becoming the PM and admitted that the economy was not his domain.

Sir Anthony Eden, 645 days
The next shortest-serving PM of the UK was Anthony Eden. His premiership came at the time of the Suez crisis. The final months of his premiership saw the erosion of the tory support and continued health deterioration. Eventually, Eden resigned on 9 January 1957, after his doctors warned him his life was at stake if he continued in office. Notably, Eden had held the Foreign Secretary office before the premiership.

Other PMs with short tenures
The other PMs with shirt tenures were Gordon Brown (1049 days), Theresa May (1106 days), James Callaghan (1124 days) and Boris Johnson (1141 days).
