Boris Johnson, who has pledged to deliver Brexit on October 31, is in the final leg of battle on Monday (July 22) with Jeremy Hunt to become the ruling Conservative party's leader and Britain's next prime minister. Johnson and Hunt are locked in a battle to succeed Theresa May, who resigned as prime minister after failing three times to get parliamentary approval for a withdrawal deal for Britain's exit from the European Union. Whoever takes over will have the job not only of trying to steer Britain out of the EU by the next deadline, October 31, but dealing with a raft of challenges from an unpredictable U.S. president to mounting tensions with Iran.
