The UK's Labour Party swept to power early on Friday after winning the country's general election, crossing the 326-seat threshold for a working majority in the House of Commons.
"A mandate like this comes with a great responsibility," Labour leader Keir Starmer told supporters at a triumphant dawn rally in London, moments after the results that sealed its landslide win were announced.
Prime Minister-elect Starmer pledged Friday to start a period of "national renewal" in the UK after his opposition Labour party defeated the ruling Conservatives in the general election.
"Today we start the next chapter -- begin the work of change, the mission of national renewal and start to rebuild our country," Starmer said in a triumphant victory speech in London after his party secured a majority in parliament.
British leader Rishi Sunak conceded defeat Friday to Starmer's main opposition Labour party in the UK general election, saying, "I take responsibility for the loss".
"Today, power will change hands in a peaceful and orderly manner with goodwill on all sides," said Sunak, as his Conservative party appeared heading for historic defeat to Labour.
Starmer will become Britain's new prime minister, as his centre-left opposition Labour party swept to a landslide general election victory, ending 14 years of right-wing Conservative rule.
"The Labour Party has won this general election, and I have called Sir Keir Starmer to congratulate him on his victory," a sombre-looking Sunak said after he was re-elected to his seat.
"Today, power will change hands in a peaceful and orderly manner with goodwill on all sides," the Tory leader added, calling the results "sobering" and saying he took responsibility for the defeat.
At a triumphant party rally in central London, Starmer, 61, told cheering activists that "change begins here" and promised a "decade of national renewal", putting "country first, party second".
But he cautioned that change would not come overnight, even as Labour snatched a swathe of Tory seats around the country, including from nine Cabinet members, and former prime minister Liz Truss.
Truss's disastrous 49-day tenure effectively sealed the Tories' fate with the public two years ago, when her unfunded tax cuts spooked markets and crashed the pound.
She had been facing a campaign to oust her by grassroots activists -- dubbed "the Turnip Taliban" -- in her rural constituency and lost by just 630 votes.
- 'Keir we go'
Labour raced past the 326 seats needed to secure an overall majority in the 650-seat parliament at 0400 GMT, with the final result expected later on Friday morning.
An exit poll for UK broadcasters published after polls closed at 2100 GMT on Thursday put Labour on course for a return to power for the first time since 2010, with 410 seats and a 170-seat majority.
The Tories would only get 131 seats in the House of Commons -- a record low -- with the right-wing vote apparently spliced by Nigel Farage's anti-immigration Reform UK party.
In another boost for the centrists, the smaller opposition Liberal Democrats ousted the Scottish National Party as the third-biggest party.
The results buck a rightward trend among Britain's closest Western allies, with the far right in France eyeing power and Donald Trump looking set for a return in the United States.
British newspapers all focused on Labour's impending return to power for the first time since Gordon Brown was ousted by David Cameron in 2010.
"Keir We Go," headlined the Labour-supporting Daily Mirror.
"Britain sees red," said The Sun, the influential Rupert Murdoch tabloid, which swung behind Labour for the first time since 2005.
Tory future
Sunak will tender his resignation to head of state King Charles III, with the monarch then asking Starmer, as the leader of the largest party in parliament, to form a government.
The Tories' worst previous election result was 156 seats in 1906. Former leader William Hague told Times Radio the projections would be "a catastrophic result in historic terms".
But Tim Bale, politics professor at Queen Mary, University of London, said it was "not as catastrophic as some were predicting" and the Tories would now need to decide how best to fight back.
Right-wing former interior minister Suella Braverman and Mordaunt, who was leader of the House of Commons, both said the Tories failed because they had not listened to the British people.
But Brexit champion Farage, who finally succeeded in becoming an MP at the eighth time of asking, has made no secret of his aim to take over the party.
"There is a massive gap on the centre-right of British politics and my job is to fill it," he said after a comfortable win in Clacton, eastern England.
To-do list
Labour's resurgence is a stunning turnaround from five years ago, when hard-left former leader Jeremy Corbyn took the party to its worst defeat since 1935 in an election dominated by Brexit.
Starmer took over in early 2020 and set about moving the party back to the centre, making it a more electable proposition and purging infighting and anti-Semitism that lost its support.
Opinion polls have put Labour consistently 20 points ahead of the Tories since Truss's resignation, giving an air of inevitability about a Labour win -- the first since Tony Blair in 2005.
Starmer is facing a daunting to-do list, with economic growth anaemic, public services overstretched and underfunded due to swingeing cuts, and households squeezed financially.
He has also promised a return of political integrity, after a chaotic period of five Tory prime ministers in 14 years, scandal and sleaze.
