British Foreign Secretary Liz Truss has entered the race to replace Boris Johnson as U.K. leader, making her the latest cabinet minister to make a move in an already fractious contest.

Truss made tax cuts the heart of her campaign, vowing to reverse a payroll tax hike that was introduced by former chancellor Rishi Sunak and pledging to make corporation tax "competitive.”

"Under my leadership, I would start cutting taxes from day one to take immediate action to help people deal with the cost of living,” she wrote in the Daily Telegraph on Sunday night.
