Rishi Sunak is facing a daunting summer. The prime minister is gearing up for a series of by-elections which will set the stage for next year’s general election – offering the public a chance to give their verdict on the government after 13 years in power.

Two of the four will take place on 20 July, to replace the former Uxbridge and South Ruislip MP Boris Johnson and his ally Nigel Adams in Selby and Ainsty.

The resignation of David Warburton, following his suspension as a Tory MP over harassment and drug abuse allegations, sets up a contest in Somerton and Frome.
