Foreign Secretary Liz Truss is running to be the next Tory leader on a pledge to reverse the controversial national insurance hike pushed through by rival Rishi Sunak.
The senior Cabinet minister, who is widely expected to be a front-runner in the already crowded race, promised to “start cutting taxes from day one” to help with the cost of living.
With newly appointed Foreign Office minister Rehman Chishti also declaring his candidacy on Sunday evening, there are now 11 Tories in the running for the top job.
