Britain’s head of state, King Charles III, officially appointed Labour leader Keir Starmer as prime minister on Friday during an audience at Buckingham Palace.

A photograph released by the palace showed the monarch shaking hands with Starmer, whose party won a landslide election victory.

The king had earlier accepted the resignation of Conservative leader Rishi Sunak.

“Sir Keir accepted His Majesty’s offer and kissed hands upon his appointment as Prime Minister and First Lord of the Treasury,” the palace stated.
