Britain's Prime Minister Boris Johnson on Friday, December 13, won an overall majority in the snap elections called over Brexit.

Johnson would return to the Downing Street as results showed the Tories had won 326 of the 650 seats in the lower House of Commons.

Meanwhile, opposition Labour Party leader Jeremy Corbyn said he would not lead the party into the next election after admitting it had been a "very disappointing night".

"This is obviously a very disappointing night for the Labour Party with the result that we've got," Corbyn said after winning his north London electoral seat.

"I will not lead the party in any future general election campaign," he said, adding that the party needed to reflect and that he would lead the party as it discussed its future.

What will the victory bring for Boris Johnson?

Johnson's win will allow him to take Britain out of the European Union in a matter of weeks. 

For Johnson, whose 20-week tenure in power has been marked by chaotic scenes in parliament and stark division on the streets over Britain's tortuous departure from the European Union, victory in Thursday's contest was vindication.

Educated at the country's most elite school and recognisable by his bombastic style, the 55-year-old must not only deliver Brexit but also convince Britons that the contentious divorce, which would lead to lengthy trade talks, is worth it.

A landslide Conservative win marks the ultimate failure of opponents of Britain's departure from the European Union who plotted to thwart a 2016 referendum vote through legislative combat in parliament and prompted some of the biggest protests in recent British history.

Johnson won an outright majority in the 650-seat parliament after an exit poll showed the Conservatives on course to win a landslide 368 seats, the biggest Conservative national election win since Margaret Thatcher's 1987 triumph.

"I think this will turn out to be a historic election that gives us now, in this new government, the chance to respect the democratic will of the British people," Johnson said after winning his seat of Uxbridge.

He said the Conservatives appeared to have won "a powerful new mandate to get Brexit done".
