Liz Truss needs to hang on as Prime Minister until the start of next year to avoid her premiership becoming the shortest in British history. The person who currently holds the title is the Tory statesman George Canning, who spent 118 full days as Prime Minister in 1827 before dying in office from ill health.
Ms Truss would overtake this number of days on January 3, 2023. There have been several Prime Ministers who for various reasons failed to last a year in the job.
They include two Conservative PMs in the past 100 years: Andrew Bonar Law, who clocked up 211 days from 1922 to 1923 before resigning due to poor health, and Alec Douglas-Home, who managed 364 days in 1963-64 until losing a general election.
