People are being pushed towards a vote for independence by the chancellor’s move to rule out a deal to share the pound, a survey suggests.
The results show 28% are more likely to back a Yes vote in September following the decision by George Osborne to reject the SNP plan to keep using sterling.
It compares with 21% who say they are now more likely to vote No, and 51% who say it makes no difference.
The findings came in a Survation poll on the day the SNP began its party conference in Aberdeen.
Earlier this month an anonymous UK Government minister was quoted as saying “of course” there will be a currency union after independence.
Downing Street and Westminster opposition parties insist the minister is wrong and strongly insist there will be no deal.
But the poll is further evidence that people in Scotland are more likely to think the chancellor is bluffing on currency.
It shows 37% think he and other Westminster leaders will agree to a formal deal, compared with 35% who think they mean what they say.
A second poll, by Panelbase, published at the same time, suggests 46% think there will be a deal on currency compared with 34% who think Mr Osborne will stick to his decision.
A YouGov poll last month suggested 45% of Scots do not believe the chancellor’s threat, compared with 40% who do.
Blair Jenkins, chief executive of Yes Scotland, said: “We now have more strong evidence that the people of Scotland have seen right through the currency bluff of George Osborne, Ed Balls and Danny Alexander.
“The currency confession from the Westminster Government minister that ‘of course’ there would be a shared sterling area between an independent Scotland and the rest of the UK reflects the reality – and that is what most Scots believe.
“There is no question that the currency bluff has backfired, and is one of the factors contributing to the growing strength of the Yes vote.”
Meanwhile, a separate survey found that people in the rest of the UK are more likely to oppose the plan for Scotland to keep sterling after independence. A poll of 1,622 people in England, Wales and Northern Ireland suggested just 26% would support a deal while 53% would not.
A spokesman for the Better Together campaign to keep Scotland in the union said: “A currency union between a separate Scotland and the continuing UK would not happen.
“The prime minister, the chancellor, shadow chancellor, chief secretary to the treasury and the permanent secretary of the treasury have all said it would not happen.
“Yesterday’s poll of people living elsewhere in the UK made it clearer than ever that they wouldn’t agree to it either. What people in Scotland need from Alex Salmond is his plan B for what would replace the pound. Would we rush to adopt the euro or would we set up a separate, unproven currency?”
