Boris Johnson, the former London mayor who campaigned on a pro-Brexit message, is poised to become Britain's next prime minister, according to polling data available Monday, one day prior to the official announcement.
Johnson's rival is Jeremy Hunt, the current secretary of state for Foreign and Commonwealth Affairs. The official winner will be announced Tuesday and will replace Theresa May, who announced her resignation in late May, amidst failed Brexit negotiations.
Since the announcement of her resignation, U.S. President Trump has backed Johnson.
Members of the governing Conservative Party can vote until 5 p.m. local time Monday. In the British Parliament system, the leaders of the political party with the most members of Parliament vote, rather than the public. In this case, the Conservative, or Tory party will vote, which is 0.25 percent of the 66 million British people, according to The Associated Press.
Ahead of Johnson's likely takeover, Senior Foreign Minister Sir Alan Duncan announced his resignation in a letter to May, while several other Tory leaders have threatened to do the same.
“It is tragic that just when we could have been the dominant intellectual and political force throughout Europe, and beyond, we have to spend every working day working beneath the dark cloud of Brexit,” Duncan wrote in the letter.
Two senior cabinet ministers, Chancellor Philip Hammond and Lord Chancellor David Gauke, also pledged to leave over the no-deal issue if Johnson wins.
