The Labour leader had his meeting in Buckingham Palace after Rishi Sunak stepped down following the worst-ever general election result for the Conservatives.
Sir Keir now takes over as the first Labour prime minister in 14 years – and the seventh Labour prime minister ever.
Following the meeting, the King’s spokesman said the King requested that Sir Keir form a new administration.
“Sir Keir accepted His Majesty’s offer and kissed hands upon his appointment as prime minister and first lord of the Treasury,” he said.
Speaking on the steps of No 10, former prime minister Mr Sunak said he would not leave his role as Conservative Party leader immediately but would do so once a leadership race begins.
“I would like to say, first and foremost, I am sorry. I have given this job my all,” he said.
“But you have sent a clear signal that the government of the United Kingdom must change. And yours is the only judgement that matters.
“I have heard your anger, your disappointment and I take responsibility for this loss.” – skynews
