Boris Johnson has taken a commanding lead in the contest to become Britain's next prime minister, winning by far the largest share of support in first-round voting by Conservative Party lawmakers.
Johnson, a former foreign secretary and leading Brexit campaigner, secured 114 of the 313 votes cast in the round, which reduced the field of candidates from 10 to seven on Thursday.
His successor as foreign secretary, Jeremy Hunt, trailed with 43 votes, followed by Environment Secretary Michael Gove with 37.
Johnson thanked supporters and tweeted: "I am delighted to win the first ballot, but we have a long way to go."
The result exceeded the expectations of Johnson's team and makes him almost certain to be among the final two candidates who will be put to a vote of 160,000 party members nationwide. The winner will become Conservative leader and British prime minister.
Three candidates were eliminated. Lawmakers Esther McVey, Mark Harper and Andrea Leadsom all failed to reach the threshold of 17 votes needed to get to the next round.
The contest is dominated by the issue of Britain's stalled departure from the European Union, with all the contenders promising to succeed where departing Prime Minister Theresa May failed and lead the country out of the bloc.
May quit as party leader last week after failing to secure Parliament's backing for her Brexit divorce deal. Britain's EU departure was originally due to take place on March 29, but has been delayed to October 31 because of the political deadlock in London.
Johnson vowed Wednesday that as prime minister he would "get Brexit done," either by renegotiating May's rejected Brexit deal or by leaving the EU on October 31 without an agreement.
"Delay means defeat" for the Conservatives, he said.
Conservative legislators will hold further elimination rounds of votes next week until two contenders remain. They will be put to a postal ballot of party members, with the winner due to be announced the week of July 22.
In addition to Johnson, Hunt and Gove, four other contenders remain in the race: ex-Brexit Secretary Dominic Raab, Home Secretary Sajid Javid, Health Secretary Matt Hancock and International Development Secretary Rory Stewart.
