Professor Ciaran Martin told the Herald on Sunday: “The UK government has no obligation to establish under what circumstances Scotland could become independent.”
He said the number 10 is “refusing to develop a policy or get into any discussion about what that framework might be like,” and added: “So for now, although in principle Scotland can become independent, in the practice can’t, no, it doesn’t matter how you vote in elections or how often you do it. “
He said the UK government “seems to be betting on it” because there is now no high demand for another referendum in Scotland.
Polls suggest a clear majority of Scots oppose Mrs Sturgeons’ timetable for a referendum next year.
Ross on Sunday urged the Scottish government to focus on “real” issues such as the cost of living, the NHS and education.
The SNP later compared his comments to those of Donald Trump, accusing him of a “shameless betrayal of democracy.”
“Denying the reality of the SNP’s 2021 election victory, which was even bigger than 2011’s, makes it sound exactly like the former US president and his supporters,” said Rona Mackay, MSP of the SNP.
A UK government spokesman said: “Now is not the time to talk about another referendum.
“People across Scotland want and look forward to seeing the two governments work together with a relentless focus on the issues that matter to them, their families and communities.”
Ian Murray, the Scottish shadow secretary, said: “This is a transparent attempt to increase division and distract from the chaos surrounding the SNP.
“Nicola Sturgeon is not in a position to teach anyone a lesson about listening to the people of Scotland, as he ignores the cost-of-living crisis he plans on people’s lives and moves forward with a costly, unwanted and damaging referendum “.
