The UK is facing a hung parliament, with neither Conservative of Labour parties able to win a majority in the country’s election.
Both parties did not reach the required 326 seats to govern in their own right, despite the Conservatives previously well ahead in polls when the election was called.
The BBC said earlier the Conservatives would end the election with 322 votes while an poll held at the end of polling indicated the party would also be short of a majority in the 650-seat House of Commons.
The Tories are projected to hold 318 seats, Labour 261 and the Scottish National Party 35.
Theresa May said after retaining her seat of Maidenhead the country would need stability following the election.
“If, as the indications have shown, if this is correct, that the Conservative Party has won the most seats and probably the most votes, then it will be incumbent on us to ensure we have that period of stability and that is exactly what we will do,” she said.
She said she would continue to focus on what was important to the nation.
“As we ran this campaign, we set out to consider the issues that are the key priorities for the British people,” Mrs May said.
“Getting the Brexit deal right, ensuring that we both identify and show how we can address the big challenges facing our country.”
“Doing what is in the national interest. That is always what I have tried to do in my time as a member of Parliament. My resolve to do that is the same this morning as it always has been.”
However, Labour party leader Jeremy Corbyn said after being re-elected in his seat of Islington North Mrs May needs to resign, claiming she has lost support.
“If there is a message from tonight’s result, it is this: The Prime Minister called the election she wanted a mandate, the mandate she has got is lost Conservative seats, lost votes, lost support and lost confidence,” he said.
“I think that’s enough for her to go, actually.”
He said he was proud of the results so far and described them as a “vote for hope for the future”.
The Conservatives said if there was a hung parliament, Mrs May would have the opportunity to form government first.
However, despite not having a majority, the Conservatives would be able to win government with 318 seats, if they were supported by 10 Democratic Unionist Party MPs.
The UK could expect new elections later in the UK summer however, under the rules in the Fixed Term Parliament Act.
Mrs May called a snap election three years ahead of schedule as an attempt to increase her party’s majority in Parliament ahead of Brexit negotiations with her party well ahead in the polls.
Mrs May’s Conservative party held a narrow lead over the Labour Party ahead of the election day but all polls suggested the Conservatives would remain in control in Parliament.
The Conservatives held a majority 330 seats in Parliament ahead of the election, compared to Labour’s 220, the Scottish National Party’s 54 seats and Liberal Democrats nine.
