LONDON—Prime Minister Boris Johnson’s Conservative Party will win a majority of 86 seats in Britain’s election, giving him the numbers in parliament he needs to deliver Brexit on Jan. 31, an exit poll indicated on Thursday.
The exit poll showed Johnson’s Conservatives would win 368 seats, enough for a comfortable outright majority in the 650-seat parliament. Labour were forecast to win 191 seats, the Scottish National Party 55 seats and the Liberal Democrats 13.
