Prime Ministers of the UK with the fewest days in office 1900-2022
Liz Truss is set to be shortest-serving Prime Minister of the United Kingdom, after resigning on October 20, 2022, just 45 days into her job. Since the Brexit vote of 2016, the UK has seen the resignation of four Prime Ministers, with Truss' predecessors, Boris Johnson and Theresa May also among the shortest-serving Prime Ministers since 1900.
