The SNP Government has been told it must publish legal advice it received about a second referendum on leaving the UK in a ruling from the information commissioner.
A ruling by the Scottish Information Commissioner Daren Fitzhenry said the release of advice into the public domain would "significantly enhance public debate" on the issue.
Pamela Nash, chief executive of Scotland in Union, said:
“This SNP administration is renowned for its secretive behaviour so this is a vital ruling that must lead to some much-needed transparency from ministers.
“But the people of Scotland do not want a second referendum any time soon and the SNP government should end its obsession with trying to divide us again.
“The last thing that Scotland needs as we recover from Covid and face a cost-of-living crisis is a legal battle over the constitution, which would cost millions of pounds and place a huge strain on civil servants.
“The government’s entire focus should be on what really matters to people – improving our schools and hospitals, investing in community services and tackling climate change.”
