The U.K. is hunting for a new prime minister after Theresa May announced her resignation. Whoever takes her place will have to forge a new relationship with President Trump.
This isn't just about personal chemistry: The U.S. has proffered a potential free-trade agreement between the two countries once the U.K. leaves the EU. But when and how Brexit actually happens could have a big impact on what the U.K.'s future with the U.S. and President Trump looks like.
President Trump is likely to get along well with the candidates who share his hard-line views on Brexit. The current front-runner in that camp, former Foreign Secretary Boris Johnson, already has the president's seal of approval: President Trump said last year Johnson would make a "great prime minister."
But the U.K. might also opt for a leader who supports the current, more moderate approach to Brexit. Chief among that group is current Foreign Secretary Jeremy Hunt, who has likened a no-deal Brexit to "political suicide" and has tangled with President Trump on Twitter in the past.
Whoever wins the leadership contest will have just a few months to negotiate the U.K.'s exit from the EU before the current deadline of Oct. 31.
