Big majority predicted for Boris Johnson and Tories with counting underway
Boris Johnson's gamble on a snap election looks to have paid off, with the Tories on course to win a big majority, according to an exit poll.
The BBC/Sky/ITV poll puts the Tories on 368 seats, with Labour predicted to win just 191 seats, the Scottish National Party 55, Liberal Democrats 13, the Brexit Party none, Plaid Cymru three and Greens one.
This would give Mr Johnson a majority of 86.
The pound soared against the dollar and the euro as the exit poll emerged.
One of the first results to come through appeared to bear out the exit poll prediction as the Conservatives won Blythe Valley with a 10% swing from Labour - a seat they had held since 1950.
Jeremy Corbyn's party clung onto Newcastle Central and Houghton and Sunderland South, but with much reduced majorities.
The Prime Minister greeted the poll by tweeting: "Thank you to everyone across our great country who voted, who volunteered, who stood as candidates. We live in the greatest democracy in the world."
If the exit poll proves to be accurate, Mr Johnson will return to Number 10 on Friday in a position to easily drive through his Brexit deal and take the UK out of the European Union next month.
The result - the largest majority for a Conservative leader since Margaret Thatcher in the 1980s - would be seen as a triumph for his tightly-controlled campaign, which was largely gaffe-free until the final week.
Mr Johnson entered the election without a majority - having just 298 Tory MPs - after some quit the party and he withdrew the whip from others when they rebelled over Brexit.
The result would, however, be a huge set-back for Labour leader Mr Corbyn.
Labour, who had 243 MPs when Parliament was dissolved last month, is forecast to lose 52 seats.
Such a poor result would be the worst for Labour in terms of seats since 1935 and would put extreme pressure on Mr Corbyn to stand down after losing a second general election in a row.
In a tweet sent as the polls closed, Mr Corbyn thanked activists.
"You're the heart of our party, and you have campaigned tirelessly to win so we can a build a fairer country. I thank you all."
Shadow chancellor John McDonnell said the exit poll was "extremely disappointing".
And shadow international trade secretary Barry Gardiner said it represented a "devastating result for us" and "all the people who were really needing a Labour victory to improve their lives".
Asked if his party needed a new leader, Mr Gardiner said: "These are things that will be discussed by the leadership of the party in the next few days."
The Tories appeared cautious after the exit poll but said a functioning majority "would mean we can now finally end the uncertainty and get Brexit done".
A Conservative spokesman said: "This is a projection, not a result, it's important we wait to see the actual results when they come in. What we do know is that voters have rejected Labour's fudge on Brexit.
"We needed this election because parliament was doing all it could to frustrate the will of the people.
"A functioning majority would mean we can now finally end the uncertainty and get Brexit done. It would allow the country to come together and move forward by delivering the change people voted for in 2016."
Labour said it was "too early to call the result" but claimed the party had "changed the debate in British politics".
A party spokesman said: "We, of course, knew this was going to be a challenging election, with Brexit at the forefront of many people's minds and our country increasingly polarised.
"But Labour has changed the debate in British politics. We have put public ownership, a green industrial revolution, an end to austerity centre stage and introduced new ideas, such as plans for free broadband and free personal care."
