Boris Johnson's resignation today puts him among the top four shortest serving British Prime Ministers in the post-war period - and means he has lasted less time in office than Theresa May.

Mr Johnson became Prime Minister on 24 July 2019, and has therefore been in post for two years and 348 days.

In comparison, Theresa May, who became Prime Minister in 2016, served for three years and 12 days until 2019.

Below is the full list of post-war Prime Ministers in order of how long they remained in the top job.
