Mel Stride has become the fourth Conservative MP to enter the race to become the party’s next leader.
The former work and pensions secretary – who now holds the shadow role – hinted his candidacy to Sky News earlier this week, saying there was a “reasonable chance” he would run.
But he has now officially joined ex-home secretary James Cleverly, former security minister Tom Tugendhat, and the last immigration minister Robert Jenrick in the contest to replace Rishi Sunak.
Nominees must have 10 backers to submit their papers to enter the race.
