Conservative leadership candidate Boris Johnson leaves his campaign offices in Westminster in Central London on July 22, 2019 on the eve of the announcement of the winner of the Conservative Party leadership contest. - Britain's leadership contest entered its finale Monday with the favourite Boris Johnson facing more defections from ministers over his Brexit plan. The month-long contest between former London mayor Johnson and Foreign Secretary Jeremy Hunt is being decided by fewer than 200,000 grassroots members of the governing Conservative Party. The winner will have three months to resolve a three-year Brexit crisis that could damage economies on both sides of the Channel and determine the fate of generations of Britons.
