Labour is confident of taking Ipswich, currently held by Conservative minister Ben Gummer, who was responsible for putting forward the party's manifesto.

Jane Ellison, a minister at the Treasury, is in deep trouble, and the Conservatives are also worried about Home Secretary Amber Rudd in Hastings.

A Tory minister has told me: "Every mile I go further north looks better for the Tories."

But I wonder what will happen if there is no prime minister who commands a majority in the House of Commons when Brexit negotiations are set to begin in 10 days time.

More than one source is reporting that the Conservatives are glum about their prospects of holding this seat.

Former Shadow Chancellor Ed Balls's lost it to Tory Andrea Jenkyns in 2015 with a slim majority of 331.

Neil Dawson is Labour's candidate for the constituency this time around.

• The Tories will be the largest party but may not have a majority, according to the general election exit poll
• The survey suggests the Tories could get 314 MPs - down 17
• Labour would get 266 - up 34
• The Lib Dems would get 14 (up six from 2015), UKIP none and the SNP 34 (down 22)
• The first few seats have been declared. None have changed hands, but in several cases the numbers have gone against the grain of the exit poll somewhat.

at the count in Paisley

As the night goes on, the atmosphere is changing. To begin with, everyone was talking about Mhairi Black, the youngest MP, retaining her seat.

The exit poll came in, with all the caveats, and in Paisley and Renfrewshire South, it suggests that Labour could take it from the SNP.

We are watching these piles very closely indeed. What's happening on the tables behind me is that - for Alison Dowling of Labour and Mhairi Black of the SNP - the piles are going up neck and neck.

There are observers around the room watching closely.

Election 2017

Former Conservative Chancellor Ken Clarke says it was "worthwhile" going to the polls to try to get a better majority.

He says having the general election in 2020, as was planned, when Brexit would really be kicking in would not have been wise.

His guess is the Conservatives look as though they are "going to have a small overall majority".

"We're obviously going to have a very interesting Parliament," he says, adding that the worst possible outcome for the country would be a hung parliament.

Mr Clarke, a staunch Remain supporter, says if the Tories secure a small overall majority, it will enable "some deeper debate on a lot of issues", especially Brexit.

It's fair to say the exit poll left Twitter stunned. BBC Trending has a roundup.

The hashtag "Hung Parliament" shot to the top of Twitter's trending list after the general election exit poll predicted that the Conservatives could lose their overall majority.

One Labour candidate sums things up...

Labour MP Sharon Hodgson has held on to Washington & Sunderland West but the Tories have made progress.

The Conservatives were looking at a 5 point increase but the vote is up by 10 points.

The Labour vote was expected to rise by 14 points according to the exit poll but is actually only 6 points higher.

Election 2017

Shadow foreign secretary Emily Thornberry sticks to her call for Theresa May to resign.

"Think about it - she basically wanted to stamp out the opposition and the country has said no," she says.

"We put forward a positive alternative. She's nowhere near a larger majority - she's failed."

Ms Thornberry admits she's "disappointed" it looks like Labour won't win outright, "but weeks ago people were asking how big her [Mrs May's] crown was going to be."

"Now it seems we could form the next government," she adds, which is "extraordinary".

Labour's John McDonnell has told Sky News that if the exit poll is right then it will be indicative of "a breakdown of trust" in Theresa May.
