Kevin Pringle, who worked for former SNP First Minister Alex Salmond, claimed the “Yes” vote to remove Scotland from the UK would this time succeed, having been voted down 55-45 per cent in 2014.
Ms Sturgeon, the current First Minister, has made clear she is “determined to save Scotland from Brexit” as she promised she would deliver a second independence referendum by 2018.
Speaking during last week’s First Minister’s Questions, she again attacked the Conservatives over Europe, accusing Theresa May of putting its “obsession with immigration” ahead of the interests of the economy.
Ms Sturgeon added: “It’s not just the case that the Tories are running toward Brexit, they want to drag Scotland kicking and screaming over that Brexit cliff-edge and I’m determined they are not going to get away with this.”

My own view is that it will be much easier to get people back again
Mr Pringle believes Brexit had created an “extreme example” of “democratic deficit”.
Speaking on BBC Sunday Politics Scotland programme, Mr Pringle said: “My own view is that it will be much easier to get people back again – if you like, the stray Lessors – and even if that’s all that happened then the referendum if there’s be another would be Yes.
“I think the framing of the referendum would be the Brexit situation, but what Nicola Sturgeon would be keen to do is put Brexit in the context of the democratic deficit which Scotland faces.
“What Brexit is an extreme example is an extreme example of the democratic deficit. Since 2010 there has been a UK Government with the support of just one Member of Parliament in Scotland.
“The English equivalent of that would be England being governed by a party which has the support of nine MPs out of 533 – obviously ridiculous and could never happen.”
This comes after Scotland’s minister for Brexit Mike Russell said that SNP MPs will “absolutely” vote against the triggering of Article 50 and starting the formal talks to leave the European Union.
The Government minister said if the party’s MPs voted in support of leaving the EU they would be endorsing the Prime Minister’s vision of an “isolationist” Britain.
According to Mr Russell a ‘hard’ Brexit – which severs ties with the EU completely – would give those campaigning for Scottish independence a “winning progress” should another vote be held.
He said: “I don’t think there is any possibility of the SNP MPs supporting the Article 50 Bill.

“Endorsing Article 50 is not just endorsing the vote in the United Kingdom – and of course the vote in Scotland was very different – it’s actually endorsing the type of position Theresa May has taken on the type of Brexit she wants, and that’s endorsing the type of country she wants.
“She wants an isolationist country, she wants a country that is inward looking and she ants a country which is rejecting the benefits of migration.
“That’s not the country any of us want to see Scotland being and that is one of the strongest reasons for saying we reject it.”
Mr Russell was keen to add that the SNPs stance was not a “threat”, but the Government had to seriously consider the options presented to them over Scotland’s future.
