Emeritus professor Alan Sked poured scorn on the SNP leader’s hopes of separation, claiming Scots would be in a “worse state than Greece” if they voted to go it alone.
Last month, Holyrood voted to give the First Minister the power to demand Westminster allow a new ballot on Scottish independence.
But, the former London School of Economics professor issued a grave warning to Ms Sturgeon, warning of the economic consequences of opting for independence.
Alan Sked argued independence would be a 'disaster' for the Scottish economy

Speaking to Russia Today, Mr Sked said: “Only about 23 per cent of the Scottish population, according to opinion polls, want a second referendum and a majority want to remain in the United Kingdom.
“That’s fairly sensible as if an independent Scotland were to exist it would soon find out that it had made a great mistake.
“After all four-and-a-half times as many exports from Scotland got to the UK as go to the EU and of course with Scotland’s dreadful economic situation, economists are now talking about a recession in Scotland where as the British economy is booming.”
He added: “It would be in a worse state than Greece.”
The emeritus professor debunked Ms Sturgeon's argument for independence
Ms Sturgeon argues Scotland being dragged out of the European Union’s single market through a hard Brexit would have a catastrophic impact on the country’s economy.

She wants Scots to be given a choice on independence before Britain’s divorce from the Brussels club is completed.
But, Mr Sked rebuked that claim, as he argued: “She doesn’t lose access to the single market, everybody in the world has access to the single market.
“Britain won’t be a member of the single market but it will have access like everybody else has."
He finished: “It’s called a single market because everybody goes to this one market, whether you’re Chinese, Albanian, American, whatever, you’re not in the single market but you have access to it.”
Meanwhile, the Scottish First Minister claims Scots will make an “informed decision” when the country votes on its UK membership.

British Prime Minister Theresa May meets Scottish First Minister Nicola Sturgeon in Glasgow, following the announcement that Scotland is to hold a second Independence Referendum
During a speech at the Political Studies Association’s annual conference in Glasgow on Tuesday, Ms Sturgeon said: “We want to ensure that the next referendum on independence gives people the information they need to come to a considered judgement.”
She added: “A key difference was that in 2014, the Scottish government set out a detailed proposal for how Scotland would become independent.
“In 2016, on the other hand, people were asked to vote for change, without being told what that change involved.”
