Labour leader Keir Starmer officially became prime minister of the United Kingdom on Friday after his party won a landslide victory in a national election.
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.
