Ian Murray had the largest majority in Scotland - 15,514 - in the 2017 election. Scottish Labour are confident he'll retain his seat tonight.

SNP candidate Deidre Brock says she's "hopeful" of being returned to parliament tonight in her Edinburgh North and Leith constituency.

The exit poll predicts that the Liberal Democrat leader Jo Swinson would lose her East Dunbartonshire seat to the SNP.

She has lost it once to the SNP before - could a repeat be on the cards?

In 2015, when John Nicolson took the seat for the SNP, the constituency had the highest turnout in the entire of the UK, at just shy of 82%. Will that hold up on a cold, dark December day?

After retaking the seat in 2017, Ms Swinson's majority is one of the healthiest in the country. She has since gained the profile of becoming her party's leader - but that also carries the risk of her being a big scalp for her opponents.

Voters here also have the widest range in choice in Scotland at this election, with eight different options on the ballot paper.

Plan B in action for the SNP.

If they have failed to lock Boris Johnson out of Downing Street, they will now argue that Scotland's distinctive standpoint must be respected. Not least with a referendum on independence.

Douglas Alexander, former Labour Foreign Secretary, says Corbynism has been tested to destruction. Ambiguity the road to ruin.

Uk government minister Michael Gove says he doesn't believe that another independence referendum in Scotland is inevitable, despite the SNP's strong showing in the exit poll.

Mr Gove told ITV that many seats in Scotland are marginal and that this could mean a very different result to initial projections.

If these exit poll figures are broadly correct Boris Johnson may just have redrawn the map.

With these figures he would have clear backing from the green benches behind him to take us out of the EU next month.

It would also mean another five years of Conservative rule with a solid majority behind him.

We are also seeing Labour going down to a fourth election defeat in a row - a serious and historic loss.

The SNP appears to have increased its dominance in Scotland.

The other parties do not appear to have made a breakthrough.

But these are early days. And it is still only a prediction.

If this exit poll proves to be correct it will see the Tories' dreams comes true and Labour’s nightmare play out.

The numbers would give the Conservatives their biggest majority since Margaret Thatcher was PM and leave them considerable room to do what they want in Parliament.

Labour would be shattered. Not since the 1930s have they failed to win 200 seats.

The SNP’s result would be extraordinary too, just shy of their best ever in 2016.

My sources in Scotland are applying plenty of caution at the moment because so many Scottish seats are marginal - but anything close to it will throw the independence question back front and centre in Scotland.

If this poll is correct - IF - then Labour would require a rethink. Is it about Leave voters asserting their view in England, against Labour's relative vacillation? Or is it about the leader? To underline, let's await more figures.

Astonishing exit poll, as it affects the UK - and Scotland. Ruth Davidson said in advance she'd skinny dip in Loch Ness if the SNP won 50 seats. Stand by Nessie. Our exit poll reckons 55 for the SNP - almost back to the apex of 2015.

If this poll is correct - IF - then stand by for three big elements. Brexit will happen. Labour will rethink. And the SNP will exercise plan B. They will argue that Scotland's voting pattern is again being over-turned.

The Exit Poll for Scotland suggests that the Liberal Democrats would lose their Scottish seats - including Jo Swinson's in East Dunbartonshire. Ming Campbell reckons that's wrong.

Caveats, caveats. This exit poll is beyond trend for the opinion polls of the campaign, increasing the Tory lead. It also goes beyond the percentage allocated to the SNP in the few Scottish polls.

And there's more. The last couple of exit polls have been pretty accurate. But others have not, including 1992 (I still bear the scars.) And more again. Around three quarters of Scottish seats are marginal - some highly marginal, some three way marginal. Difficult to drill down from one poll to individual seats. Keep watching!!!

The SNP could be on course to win 55 of the 59 seats in Scotland, according to an exit poll published as voting ends in the UK general election.

If the forecast is correct, it would see the SNP win 20 more seats than the 35 it won in 2017.

The poll, carried out on behalf of the BBC, ITV and Sky News, also suggests the Conservatives could win 368 seats, Labour 191 and the Lib Dems 13.

That would mean the Conservatives would have an overall majority of 86.

The predicted result would be a remarkable success for the SNP, and would see the party return a similar number of MPs to the historic 56 it won in the 2015 general election.
