LONDON, England (AP) — Former Foreign Secretary Boris Johnson increased his lead in the race to become Britain’s next prime minister yesterday, in a Conservative Party vote that eliminated one of his rivals and enabled upstart candidate Rory Stewart to defy expectations by remaining in the contest.

Johnson, a flamboyant former foreign secretary, won 126 of the 313 votes cast by Conservative lawmakers in their second round of balloting. The vote left five contenders vying to be the Tory leader who will succeed Theresa May as prime minister, and all but guaranteed Johnson would be one of the two candidates competing in a run-off decided by rank and file party members as well as elected politicians.

Jeremy Hunt, who followed Johnson as foreign secretary in May’s Government, had the next-highest number of votes with 42. Hunt Environment Secretary Michael Gove, Home Secretary Sajid Javid, and Stewart all trailed far behind in what is now effectively a race for second place.

Ex-Brexit Secretary Dominic Raab got only 30 votes, three short of the threshold needed to go through to the next round.

After lawmakers’ votes were counted, Johnson and the other remaining candidates traded barbs about Brexit and their plans for the economy, the welfare system, and the environment — in a messy, fractious televised debate. Johnson was accused of trying to dodge scrutiny after he skipped an earlier debate and a question session with journalists.

Tory lawmakers will vote again today and Thursday, eliminating at least one candidate each time. The final two contenders will go to a postal ballot of all 160,000 Conservative Party members nationwide.

The winner who will replace May is due to be announced in late July. May stepped down as party leader earlier this month after failing to secure parliament’s approval for her Brexit deal. She is leading the Government until her successor is picked.

Johnson insists the UK must leave the bloc on the rescheduled date of October 31, with or without a divorce deal to smooth the way.

He said during the BBC debate there would be a “catastrophic loss of confidence in politics” if Brexit was delayed any further. The withdrawal, originally set for May 29, was pushed back after May sought two extensions from the EU.

The EU says it won’t reopen the Brexit agreement it struck with May’s Government, which has been rejected three times by Britain’s Parliament. Many economists and businesses say a no-deal exit would cause economic turmoil by ripping up the rules that govern trade between Britain and the EU.
