Who is Keir Starmer, the man likely to be the British prime minister?

London — When Keir Starmer was elected to lead Britain's Labour Party in 2020, right after the party suffered its worst general election defeat in 85 years, he made it his mission to make the party "electable."

Four years later, and after 14 years of governments led by the rival Conservative Party, Starmer is poised to take Britain's top job. Exit polls from Thursday's parliamentary elections show it's not really about whether Labour will win enough seats for Starmer to become the prime minister and form the next government, but by how wide a margin. 

The 61-year-old has faced years of criticism for a perceived lack of charisma, but his methodical mission to drag Labour back toward the center of British politics and broaden its appeal to voters, appears to have worked. Starmer and Labour have also, indisputably, capitalized on years of economic pain and political chaos under the Conservative Party, who look set to have their parliamentary majority eviscerated.
