Theresa May has overtaken another prime minister in terms of number of days in office.

Her premiership has now clocked up 1,079 days – one more than the total managed by the Conservative politician Neville Chamberlain, who was prime minister between 1937 and 1940.

A few weeks ago Mrs May overtook a more recent predecessor: Labour’s Gordon Brown, who spent 1,049 days as prime minister from 2007 to 2010.

When Mrs May stands down as prime minister on July 24 2019, she will have spent a total of 1,106 days in the job.

She will rank as the prime minister with the seventh shortest time in office since 1900.

Had she been able to continue until August 12, she would have overtaken another PM: Jim Callaghan, whose premiership lasted 1,124 days from 1976 to 1979.

When Theresa May hands over to her successor, there will be 1,016 days until the statutory date of the next general election (May 5 2022) – meaning that if the next PM goes on to lose that election, they will have served a shorter term as prime minister than Mrs May.
