So that's it. The 2015 general election is over. Below are the final results and a breakdown of how it all unfolded.
Conservatives – 331 seats Labour – 232 SNP – 56 Liberal Democrats – 8 UKIP – 1 Other - 22
David Cameron returns to Downing Street with a majority Conservative government.
The final result of the 2015 general election has arrived - the Conservatives have won St Ives from the Liberal Democrats.
The result means the Tories have won 331 seats, which represents a majority of 12.
Their former coalition partners, the Lib Dems, on the other hand have won just eight and in the process lost £170,000 in parliamentary deposits.
David Cameron, Nick Clegg, Ed Miliband and Nicola Sturgeon have appeared in public together just hours after two of the main parties' leaders resigned.
The politicians lined up at the Cenotaph in central London as part of commemorations marking the 70th anniversary of VE Day, when World War II came to an end in Europe.
Harriet Harman will stand down as Labour's deputy leader after the party has chosen a successor to Ed Miliband, who announced his resignation today.
She said in a statement: "On the resignation of Ed Miliband as Leader of the Labour Party I, as his deputy, am stepping forward to be acting leader until a new leader is elected by the party.
"With a new leadership team in place, after what has undoubtedly been a serious defeat, the Labour Party will be best placed to be the strong opposition this country needs - defending our NHS and our public services, and fighting for fairness, equality and social justice.
"That determination will be all the fiercer in the face of this Tory government."
Harman, who was returned as the MP for Camberwell and Peckham with a strong majority, will remain as acting leader of the party until a leader is elected.
Cameron made a series of pledges in his victory speech.
The prime minister said the Conservative government will deliver an in/out referendum on membership of the European Union and said the devolution promised to Scotland, Wales, and Northern Ireland would be delivered.
He said his government would focus on rebalancing the economy and that "together we can make Great Britain greater still".
David Cameron has spoken on the steps of 10 Downing Street after securing a majority Conservative government.
The prime minister thanked his former coalition partner Nick Clegg, who earlier this morning stepped down as the leader of the Liberal Democrats after a terrible election night.
He mentioned Ed Miliband, who has also resigned, and said the former Labour leader was "in public service for all the right reasons".
As the dust starts to settle, BuzzFeed UK's news director, Robert Colvile, has put forward eight questions about the election that really need an answer.
Ed Miliband has announced that he is resigning as leader of the Labour party.
He said on Friday afternoon: "I believe that Britain needed a Labour government. I still do, but the British public decided otherwise. I take total responsibility.
"I am so sorry to all of those colleagues who lost their seats."
In a light-hearted moment, Miliband thanked the general public "for the selfies" and referenced his online community of teenage fangirls.
"Thank you for the most unlikely cult of the 21st century – the #Milifandom," he said.
Nick Clegg has announced that he is resigning as the Liberal Democrats' leader following a disastrous night for the party.
At a speech in central London, the deputy prime minister said the results "have been immeasurably more crushing and unkind" than he expected.
"For that I must take responsibility and resign as leader of the Liberal Democrats," he said.
Clegg defended the decision to form a coalition government with the Conservatives in 2010, saying: "To have served my country at a time of crisis is an honour that will stay with me forever."
But he attacked the record of right-wing parties. "Fear and grievance has won, liberalism has lost," he said.
"Our party will come back, it will win again. It will take patience, resilience, and grit."
Nigel Farage has announced that he is resigning as UKIP leader following his failure to win South Thanet.
Liberal Democrat leader and deputy prime minister Nick Clegg is due to give a speech at 11:30am in which he is expected to announce his resignation.
The Lib Dems won 57 seats in the 2010 general election. They have so far only won eight this time round.
Some people are waking up Friday morning and realising the election didn't go quite the way they hoped. Here's Mark Di Stefano with 19 GIFs that perfectly describe how Labour supporters feel right now.
In a series of tweets, Ed Miliband took personal responsibility for Labour's defeat.
He also thanked his supporters on Instagram.
"I've just thanked Labour's staff. They are a credit to our party, and, driven by a passion to serve, they are a credit to our country. Defeats are hard, but we're a party that will never stop fighting for the working people of this country."
UKIP leader Nigel Farage has failed to become an MP.
Farage came second in South Thanet to the Conservatives.
He has said he would resign if he failed to be elected, but he did not resign immediately following the results.
"An enormous weight has been lifted from my shoulders," he said, "and I've never felt happier."
Here's a list of the Labour MPs who could replace Ed Miliband if he steps down as party leader today.
Shadow home secretary, Yvette Cooper, could become the first female leader of the Labour party. She has a clear run at it now her husband Ed Balls has lost his Commons seat.
Her odds of winning are currently listed at 7/2.
David Cameron is expected to visit the Queen around 12:30pm, where he will be asked to form the next government.
Ed Miliband is currently inside Labour's headquarters speaking to party members. The 45-year-old could step down as party leader in the next few hours.
The BBC is reporting that Labour leader Ed Miliband could announce his resignation at midday.
Miliband is set to give a speech to Labour supporters at 12pm in which it is thought he will step down following last night's result.
Andy Burnham and Yvette Cooper are currently the leading contenders to succeed Miliband.
We're still waiting for the result out of South Thanet. It could be at least another hour until we learn Nigel Farage's fate.
The UKIP leader has said he will resign if he fails to be elected.
BALLS OUT. Sensational news. The shadow chancellor has lost his seat in Morley and Outwood by just over 400 votes.
The news compounds what has been a miserable night for Labour, and amplifies the fact that the party seems to have seeped working-class votes to UKIP.
The Conservative press team summarised the news as follows:
On the BBC, Andrew Neil has just handed Paddy Ashdown a hat, after his earlier comments that he'd eat one publicly if last night's exit poll was correct. Unfortunately for viewers, he didn't. And neither did he eat any of these. Poor Paddy.
If you have an opinion on what kind of hat Paddy Ashdown should eat, you can vote here.
It's been a terrible night for the Lib Dems. Here's a list of the party's few remaining MPs.
This is the story behind the SNP's absolutely incredible election victory in Scotland.
Scotland went to bed on Thursday night with six SNP MPs, it has woken up with 56. The three main parties have just one MP each left in Scotland.
And here is a list of all the Liberal Democrat MPs so far. There are currently just eight, down from 56.
David Cameron and his wife, Samantha, have returned to 10 Downing Street.
The two main results we're still waiting for are Morley and Outwood – previously held by Labour's Ed Balls – and South Thanet, where UKIP's Nigel Farage is standing.
Over in Brighton Pavilion, the Greens still have an MP. Caroline Lucas comfortably retained the seat with a whopping 42%, an 11% swing in her favour.
The Greens failed to gain Bristol West, which was big target of theirs, so Lucas remains their sole MP.
If you've been up all night, you're not hallucinating. That man is in a helmet and battle gear. It's independent candidate Jesse Rae in Berwickshire, Roxborough and Selkirk, another seat the Lib Dems lost to the SNP. Here's Jamie Ross with more.
BuzzFeed News' Robert Colvile has a handy round-up of 16 things the election has told us about British politics. Here's a sneak preview:
Balls to the wall. It's been rumoured all night that the shadow chancellor could be set to lose his seat in Morley and Outwood, and a recount has just been ordered.
David Cameron has tweeted this picture of him hugging his wife Samantha.
As BuzzFeed UK political reporter Siraj Datoo points out, he's not the first political leader to do this.
Also, he's not really kissing her right, is he? Ryan Broderick reports.
As, BuzzFeed News' Hussein Kesvani reports, George Galloway has been reported to the police by Bradford city council for possibly breaking electoral law.
OK. Breathe. Here are the big stories of the night.
Labour has been blown away by the SNP in Scotland. At the time of writing, 34 Labour MPs have been defeated by Nicola Sturgeon's nationalist surge.
Among the victims: shadow cabinet member Douglas Alexander, defeated by 20-year-old student Mhairi Black, and Scottish Labour leader Jim Murphy. Here is a handy guide to every Scottish Labour MP left.
The Liberal Democrats are being wiped out across the board. Danny Alexander, Vince Cable, Charles Kennedy, Simon Hughes, Ed Davey, Lynne Featherstone, Jo Swinson, and David Laws have all lost their seats.
The Tories have made gains overall, although they haven't won across the board – employment minister Esther McVey lost her marginal seat in Wirral West, a key Labour target.
George Galloway lost his seat in Bradford West, and has also been reported to the police.
Ukip's Mark Reckless lost his seat in Rochester & Strood, and reports suggest that Nigel Farage may be in trouble in South Thanet.
Basically: this wasn't an election. This was the Red Wedding.
Danny Alexander tells the BBC's David Dimbleby that Britain will see the true side of the Tories if they're left to govern without the Lib Dems. During the campaign he told BuzzFeed News' Emily Ashton that the Tories "piss him off". No love lost there.
Although Tory-to-UKIP defector Douglas Carswell retained his seat earlier, his colleague Mark Reckless hasn't been so lucky in Rochester and Strood, losing his seat to the Conservatives. Some of his old Tory colleagues are delighted:
As rumoured earlier in the night, George Galloway has lost his Bradford West seat to Labour. Just look at his face.
His victorious Labour opponent, Naz Shah, opened up publicly during the campaign about how her mother killed her abusive partner while she was a child. Read Jim Waterson's report from March here.
The controversial Respect leader also managed to get into a huge Twitter spat with a brewery during the campaign. Suffice to say, the brewery is pleased with tonight's news.
Ed Miliband has tweeted about tonight's results, thanking Labour supporters.
At exactly the same time (6.02am), David Cameron also tweeted, reiterating the "one nation" line of his speech in Witney.
Compounding the Lib Dems' misery, Danny Alexander has lost his Inverness seat by more than 10,000 votes. SNP's Drew Hendry took it with 28,838.
David Cameron has held on to his Witney seat. "It's a very strong night for the Conservative party," he says, with "a positive response to a positive campaign".
Speaking on the BBC, Conservative Esther McVey bemoaned the campaign against her in Wirral West, calling it "the dark side of politics".
She specifically referenced attacks by Labour's John McDonnell, who suggested "lynching" McVey, and John Prescott, who was criticised last month for saying people only knew who she was because of her "lovely dress".
Ed Miliband, unsurprisingly, held his Doncaster North seat easily. He got 20,708 votes, with UKIP in second with 8,928.
"This has clearly been a very disappointing and difficult night for the Labour party," he said.
