The king shook hands with Starmer, whose party achieved a huge election victory, in a photo made public by the palace.
Rishi Sunak, the leader of the Conservatives, resigned, and the king accepted it earlier.
A statement from the palace said, “The King received in audience The Right Honourable Sir Keir Starmer MP today and requested him to form a new Administration.”

“Upon being appointed as Prime Minister and First Lord of the Treasury, Sir Keir accepted His Majesty’s offer and exchanged handshakes.”

Following his center-left opposition Labour party’s resounding victory in the general election, Keir Starmer was sworn in as the new prime minister of Britain. It puts an end to the right-wing Conservatives’ 14-year rule.
