Theresa May has indicated her intention to stand down before the next round of Brexit talks – but there are a number of key milestones she could pass before the end of her premiership.
– June 27 2019: Mrs May overtakes another prime minister: Neville Chamberlain, whose premiership lasted two years and 348 days from 1937 to 1940.
– July 13 2019: The third anniversary of Mrs May becoming prime minister.
– August 12 2019: A chance to outrun another PM: Jim Callaghan, whose premiership lasted three years and 29 days from 1976 to 1979.
– December 8 2019: Should Theresa May still be in office on this date, she will pass another of her predecessors: Arthur Balfour, prime minister for three years and 146 days from 1902 to 1905.
