Since filing my blog earlier, Alex Salmond has announced he's stepping down as SNP leader and First Minister, once a successor is elected.

Asked about future strategy, he made clear to journalists that the "once in a generation" view was his and not a pledge which will bind his successor.

In saying the SNP will "hold Westminster's feet to the fire" on new powers for Holyrood, he left little doubt that this form of torture could well include the prospect of another referendum.

It came with a sting for his successor, whoever she may be - his observation that there's now a movement of 'Yessers' and other activists who are changing politics, and holding political leaders to account.

To be clear, tonight's ruckus in George Sq is not a standoff btw Yes and No campaigners - it's hoolies turning up who want a fight

Shadow Scottish Secretary Margaret Curran told BBC News there was a "deep disillusionment" with the way politics is conducted, particularly at Westminster.

She said the proposals for devolution of powers in England would not slow down the promised change in Scotland.

"The extra powers for the Scottish Parliament can be clearly implemented because we have been talking about them and planning them for some period now," she said.

"The new proposals from the prime minister I don't think are thought through and he's not clear about them in the way that we are about Scotland."

James Adams: Whichever side of the debate people have found themselves on no one can deny the impact that Alex Salmond has had on Scottish politics. He managed to lead the SNP to a victory that broke the Holyrood system designed to stop a majority and take the country into a referendum that may well permanently change UK politics for better or worse.

Alastair Milne: Nice of Salmond to "accept" the result, did he think he had an alternative? An arrogant egotist, won't be missed.

Horrible end to day when people absorbing #indyref result but a bunch of people wanting a Friday night fight.

Some will ask 'why on earth are politicians talking about constitutional change on the very day the Scottish people rejected independence?'

The answer is clear and it is here in Glasgow. The people of this great city voted by a majority to leave the UK. The anger they feel at the way Westminster currently runs things is felt up and down what remains our United Kingdom.

Actor Brian Cox, who is from Dundee, said it is the "Yes city of Scotland".

"We are all very proud of that," he said

Scottish actor Brian Cox, who has been campaigning for a "Yes" vote, told BBC News that Alex Salmond was "head and shoulders above any other political leader in these islands".

He said: "I was not always a fan but I certainly am now. I have watched him grown and be such a statesman as a result of this."

Mr Cox said he thought Alex Salmond would be "at the negotiating table" on the future of Scotland even if he is no longer first minister.

He said: "He'll want to see that we don't get a bad deal. If you think about it, being leader and being head of negotiations on this so-called vow would be a difficult two jobs to do."

"Yes" campaigners in Dundee held a final rally today in the city. Dundee voted "Yes" to independence in yesterday's referendum, by the highest margin of any local authority in Scotland.

A Police Scotland spokeswoman has said that there are approximately 100 people from each side in George Square in Glasgow.

There has been some minor disorder which has been dealt with quickly, with no arrests.

The square is closed to traffic with local diversions in place.

It is very tense in the square. It has calmed down a bit but is still very tense.

Both sides have been throwing things, the police are in the middle trying to keep both sides apart.

One side is singing Flower of Scotland and the other is singing Rule Britannia.

The Telegraph has published a video on their website, external which allegedly shows their reporter Ben Riley-Smith being "barred" from entering Alex Salmond's resignation press conference.

Speaking on the George Square trouble, Lib Dem MP Sir Menzies Campbell said: "For people like me who are committed to the democratic process and who have valued the way in which this campaign has been conducted until now, it is extremely disappointing.

"I hope that police will be able to make calm heads prevail and people will go home. The best possible thing would be a heavy shower in George Square. That is often a way of dispersing people who are ready to make trouble."

Chris and Colin Weir, the multi-millionaire lottery winners who helped bankroll the "Yes" campaign, said: "Whilst saddened at his decision, Alex Salmond has nothing to reproach himself for.

"He has energised our nation, not just in this campaign, but in all his years of service to Scotland. He has articulated the aspirations of a nation not just as a party leader but as Scotland's most successful first minister ever.

"We wish him well and thank him for his part in making Scotland the confident, forward looking country it is today."
