There are early signs that perhaps some Labour voters may simply have stayed at home.

The fall in the turnout is three points on average in seats where more than 55% voted Labour in 2017, while it is only down by a point in those where less than 35% did so.

Ian Murray, who is hoping to hold Edinburgh South for Labour, says: "Tonight is an absolute disaster for Labour."

"There's got to be a change of direction."

"The experiment of Ed Milliband didn't work and the experiment of Jeremy Corbyn has made it worse."

Could Amy Callaghan win Liberal Democrat Jo Swinson's seat?

Ged Killen, the defeated Labour candidate in Rutherglen said Jeremy Corbyn had not gone down well with voters.

"We can't escape the fact that Jeremy Corbyn was a divisive figure in this election," he said.

"His name came up on just about every single door I went to, particularly among traditional Labour voters, who were struggling to get on board with what he was putting forward in this election."

Mr Killen said he wanted to hear Mr Corbyn accept responsibility for his part in the defeat.

He said it looks like it is going to be a very bad night for Labour.

The SNP's Alan Brown holds Kilmarnock & Loudoun.

The SNP gain Angus from the Conservatives.

The SNP's Margaret Ferrier has kicked out Labour's Ged Killen in Rutherglen and Hamilton West - the SNP's first scalp of the night.

She won 23,775 votes compared with his 18,545 - a 5.1% swing.

That is slightly less than the exit poll predicted but it is still quite a win.

The BBC's Scotland editor, Sarah Smith, says the SNP will be "much cheered by this as they have been finding it difficult to believe the exit poll of 55 seats".

However, the BBC Scotland editor says they are confident their vote share will go up.

"There are serious consequences if this is repeated across the country," she says.

"When the SNP said to Scottish voters a vote for them was for an independence referendum. the Scots turned out.

"It was a real risk for the nationalists to go into the election saying it was about independence as it can galvanise Unionists.

"But if the SNP win... it will look like a resolute mandate for that referendum."

Sarah Smith also says the results would show how Scotland and the rest of the UK were "moving in totally different directions".

If the SNP is above 50 seats or so, and meanwhile so much of England seems to be turning blue, that poses a very serious question.

It really raises the tension over the Union again. It may well be that the results of tonight are going to set up a very, very tense situation between the politicians of Scotland and the politicians of England - and a Conservative PM who is in office because of a solid majority that he has got from England and maybe from parts of Wales.

Remember last time, although the Tories had a terrible night, they actually ended up with 13 MPs from Scotland - Scotland saved Teresa May. Boris Johnson looks to be winning significantly south of the border, but without Scotland - and that may well have very big consequences for his time in government.

More about Rutherglen.

SNP vote not as high as the exit poll suggested.

Labour vote not as dire.

So yet more caveats about that exit poll. But still excellent result for SNP.

Many congratulations to the returning MP Margaret Ferrier.
