The UK Prime Minister, Rishi Sunak, has called for a general election on July 4, which will see him go up against Labour’s Sir Keir Starmer.
While Mr Sunak has been prime minister for about a year and half, the Conservatives have had several leaders in recent years, such as Liz Truss, Boris Johnson, and Theresa May.
Since 1937, the average length of time a prime minister serves is five years. The last PM to serve more than five years was David Cameron, who held the position from 2010 to 2016.
Below is the full list of post-war prime ministers in order of how long they remained in the top job.
