A "Yes" victory could put Northern Ireland's constitutional status in question.

If there is a "No", there will be a debate over what extra powers, if any, should be given to Stormont. That could include devolution of corporation tax to help NI compete with the lower rate of corporation tax in the Republic of Ireland.

Sandy Buchanan, 53, said he was glad to witness the count. "It seems like the logical conclusion to what's been a remarkable campaign," he said.

His sister, Elizabeth Buchanan, 49, added: "Normally you just put your cross on the paper and that's it. Watching it makes you really feel part of it."

Labour MP Thomas Doherty, spokesman for the No Campaign in Fife, has said he is confident that Fife will be a "No", based on the latest YouGov poll.

He said Kirkcaldy would be the key part of the region to watch as "Yes" could do well there, but they would have to be ahead of "No" by some margin to dent Dunfermline, North East and West Fife where he said the "No" vote was solid.

"Yes" could do well in Glenrothes due to the town being representated by SNP MSP Patricia Marwick, he added.

It has been suggested that the count result here could be later than 04:00 and closer to 06:00.

Scotland's only Conservative MP, David Mundell, is at the count in Dumfries and says the boxes from Stranraer were not expected until 01:00.

He told BBC Scotland: "Everybody recognises that if there is a Yes vote in Dumfries and Galloway then Scotland will be independent so I'm expecting a No vote. The initial signs here are encouraging but we have such a high turnout, so many people who don't normally vote, it is very difficult to make predictions.

"It is a huge turnout. Particularly in some of the rural areas. In one of the boxes 100% of the people who have been available to vote have done so."

Official figures from Clackmannanshire put the turnout at 89%.

The evidence from throughout Scotland is of a large, indeed a phenomenal, turnout. A series of questions arise from that.

1. Will this benefit one side or the other?

That depends upon differential turnout. Is one side or the other feeling more motivated, more inclined to participate? It had been thought that the more motivated side would be Yes. It had been thought this could be worth 1% or 2% in the final tally.

However, at these huge levels of interest, that may be open to challenge. It seems that the entirety of Scotland is engaged. We shall see.

Former Scottish first minister Henry McLeish said he had been a "reluctant" No voter.

The former Labour MP and MSP said he had been "intensely annoyed" by the No campaign's approach of "fear and scare".

He said: "There is an old Scottish word - thrawn - which essentially means the more you tell people they can't do something, the more they are likely to say 'I might want to do it'."

Alistair Carmichael, who is Lib Dem MP for Orkney and Shetland, calls for more powers for Scotland's islands and alleges "Alex Salmond runs the most centralised government in western Europe right now."

SNP MSP Humza Yousaf tells the BBC he does not foresee new powers from Westminster "coming at all".

Counting is well under way at Alloa Town Hall. Election officials say they have packed in as many staff as the hall will take.
