The Conservatives lost to the resurgent Labour Party in Selby and Ainsty, a region in the north of England where the Sunak’s party had enjoyed a commanding majority.
A second seat, Somerton and Frome, was won by the Liberal Democrats, a centrist party.
The Conservatives just managed to hold on to a third seat, Uxbridge and South Ruislip, the constituency held by former Prime Minister Boris Johnson until his resignation from parliament last month, although Labour significantly grew its share of the vote.
