Cameron heads back to Downing Street
David Cameron remains in 10 Downing Street as Prime Minister, as the Conservatives gain a majority of seats in the General Election.
Speaking after he won his own seat in Witney in Oxfordshire, Mr Cameron said it was too early to say what the final result would be but that he hoped to govern for everyone.
He said: "One Nation, one United Kingdom, that is how I will govern if I am fortunate enough to form a government in the coming days".
He made clear he was determined not to allow the rising tide of nationalism to lead to the break-up of the United Kingdom, adding: "I want to bring our country together, our United Kingdom together, not least by implementing as fast as we can the devolution that we rightly promised and came together with other parties to agree both for Wales and for Scotland."
Mr Cameron is now set to visit the Queen at Buckingham Palace this afternoon to confirm his second term as Prime Minister.
But it was a dramatic night which saw the Scottish National Party sweep Labour out of almost all its strongholds north of the border.
Their election campaign chief and shadow foreign secretary Douglas Alexander, was beaten by student 20-year-old Mhairi Black, who is Britain's youngest MP.
Speculation is also mounting that Ed Miliband could stand down from the party today.
Speaking after he holds his seat in Doncaster North he said: "This has clearly been a very disappointing and difficult night for the Labour Party."
The Liberal Democrats suffered savage losses, with Energy Secretary Ed Davey and Business Secretary Vince Cable both losing their seats.
Its leader Nick Clegg described the night as "cruel and punishing."
If Ukip's leader Nigel Farage fails to win his seat, he has reportedly said he too will resign.
His party has amassed millions of votes in England, more than the SNP in Scotland, but they have struggled to convert them into seats.
The rest of the results are due in by lunchtime.
David Cameron can now form a majority Conservative government without the need for a coalition or the formal support of other parties.
