Keir Starmer is officially the new UK prime minister

Labour leader Keir Starmer officially became prime minister of the United Kingdom on Friday.

Starmer received the blessing of King Charles III to form a government in a ceremony known as the “kissing of hands.” A photo of the occasion served as the official announcement of Starmer’s new title.

Earlier on Friday, Rishi Sunak offered his resignation as prime minister to the king.

Voters in the U.K. cast their ballots Thursday in a national election to choose the 650 lawmakers who will sit in Parliament for the next five years.

After more than a decade in power under five different prime ministers, Sunak’s Conservatives suffered a major defeat.

Starmer arrives at Buckingham Palace for meeting with the king

Labour leader Keir Starmer has arrived at Buckingham Palace to accept the request of King Charles III to form a government after his party’s landslide victory.

In a ceremony known as the “kissing of hands,” Starmer will officially become U.K. prime minister. He will then head to his official residence at 10 Downing Street.

Starmer’s arrival at the palace is part of the choreography of changing governments that harkens back to a time when the king exercised supreme power and chose his preeminent minister – the prime minister – to run his government.

The modern-day constitutional monarchy echoes that tradition, with the king officially offering the post to the party that holds a majority in the House of Commons.

Earlier in the day, outgoing Prime Minister Rishi Sunak offered his resignation to the king.

Sunak resigns

Rishi Sunak has departed from Buckingham Palace following his resignation as prime minister, after the Conservative Party suffered staggering losses in the general election.

Sunak officially left the post after tendering his resignation to King Charles III in his final audience with the monarch. Sunak was driven to the palace in a chauffeur-driven ministerial car, and left in a private vehicle.

“This is a difficult day, but I leave this job honored to have been prime minister of the best country in the world,” Sunak said in his final speech outside 10 Downing Street.

Sunak wished his victorious rival, Labour leader Keir Starmer, all the best: “Whatever our differences in this campaign, he is a decent, public-spirited man who I respect.”

Sunak said he had given the job his all.

Sunak conceded defeat earlier in the morning as vote counts confirmed exit polls that had projected a landslide defeat for his Conservatives to the Labour Party.

After Sunak resigns, Starmer will go to the palace to seek the king’s blessing to form a government. After performing the “kissing of hands,” the new prime minister will head to his official residence, where he is expected to speak.
