Britain's largest opposition Labour Party swept the Conservative Party out of power for the first time in 14 years in a landslide election win.

Public broadcaster BBC said Labour had taken 412 of 650 seats in the House of Commons as of Friday morning, with vote counting almost complete. Labour doubled its number of seats in the contest.

The party's leader Keir Starmer delivered a victory speech in front of supporters in London. He said, "We did it," and, "Change begins now."

Meanwhile, Prime Minister Rishi Sunak's Conservative Party took only 121 seats, losing more than 200.

Sunak conceded his party's defeat. He said the Labour Party had won, and that he had called Starmer to congratulate him. Sunak also said, "I take responsibility for the loss."

Conservative Party members who lost their seats include former Prime Minister Liz Truss, Defence Secretary Grant Shapps and Justice Secretary Alex Chalk.

Among other parties, the Liberal Democrats won 71 seats, the Scottish National Party secured nine and the rightist Reform UK took four.
