Keir Starmer, on Monday, resigned from office as Prime Minister of the United Kingdom, following weeks of internal revolt within the Labour Party.

The development set the stage for a rapid leadership transition that is increasingly expected to elevate former Manchester mayor Andy Burnham to Downing Street.

Announcing his departure outside 10 Downing Street, Starmer said he would remain in office only long enough to oversee an orderly handover.

“Every decision I’ve taken has been about putting the country I love first,” he said, according to a New York Times report, adding that, “That is why I will resign as leader of the Labour Party.”

In an emotional address, he added: “I will give my successor my full and unequivocal support,” while thanking his wife Victoria, who he described as “a rock by my side.”
