A third of SNP supporters would be less likely to vote for independence if Scotland has to join the euro currency, a poll has suggested.
Two-fifths of Scots are against independence, the new poll by anti-independence campaign Better Together suggests, but 33% said they would be less likely to back it if Scotland had to join the troubled single currency.
The percentage is slightly higher amongst SNP supporters (34%) and higher still amongst Labour supporters (37%).
The poll question is predicated upon the assertion that an independent Scotland "would need to adopt the euro".
Experts are divided over whether Scotland would be a joint successor state with the rest of the UK, inheriting its opt-outs from the euro and the Schengen passport-free travel area, or an accession state with the requirement to reapply.
No member state has ever separated so there is no precedent for it in EU law.
It is unclear whether the Scottish Government has taken its own legal advice as it has launched a court challenge against a request by the information watchdog to say whether it exists.
The poll carried out by YouGov suggests that more than three quarters (77%) of Scots think the SNP administration should reveal whether it has taken legal advice, including three-fifths of its own supporters.
Only 13% think the Scottish Government is right to withhold the information, rising to 28% amongst SNP supporters.
The Scottish Government insists disclosure would breach the Ministerial Code, which protects the confidentiality of legal advice unless there is a compelling public interest to release it.
