The rollercoaster ride for sterling continues, with the pound falling again to be 1.8% lower at $1.2719.

Sean Callow, senior currency analyst at Westpac, predicts that a hung parliament would strip the currency of its gains since the election was called to leave it trading at about $1.25.

"But given the patchy history of exit polls, this time we will have to wait for the seat by seat results, setting the pound up for a volatile day," he adds.

In Middlesbrough, a 5% swing to the Labour Party was expected by the exit poll, but in practice there is a 1 point swing to the Conservatives.

The exit poll has underestimated the Conservative performance in much of the North East of England. But what is far less clear is that it has done so across England as a whole.

Darlington was a crucial seat for the Conservatives if they were to secure "a chunky majority", BBC political editor Laura Kuenssberg says, but Labour has held on.

The vote swing in Darlington is from Labour to the Conservatives was 0.2%.

BBC Oxford's Sophie Law is at the count in David Cameron's former Witney constituency in Oxfordshire, and has spotted a "fist bump" between two Lib Dems watching votes being counted.

Witney used to be considered one of the country's safest seats, but after the Tory leader stepped down his replacement Robert Courts was elected with a much reduced majority.

Sophie said: "The feeling has been that the Lib Dems are in a strong place at the moment and this could be the year they do it."

Exit poll may well be wrong, says Tory David Jones

International Trade Secretary Liam Fox thinks it's "entirely possible we will still get a majority" as there are "very differential results across the country".

He won't be drawn into saying how the Conservatives would behave as a minority government, explaining "I'm not going to give positions when we don't know what the next Parliament looks like."

He won't comment either on Theresa May's future, saying only it's "very early" and he's "pretty happy we might outperform" the exit poll.

If the Tories do not win an overall majority, Theresa May has lost her mandate, a Labour AM claims.

The BBC's Andrew Marr says no-one expected the Tory campaign to be "so faltering, so many missed steps" and for Theresa May to look so "unhappy".

By contrast, he said Jeremy Corbyn appeared to have had "a cracking campaign".
