The Scottish government has said it will publish the UK government’s controversial Brexit briefing paper if it is given it.
The document, which was leaked to Buzzfeed earlier this week, predicts that Brexit will hit the UK economy.
The UK government said releasing the analysis to the public could damage its negotiations with the EU.
But Scotland’s Brexit secretary, Michael Russell, said the public had a right to know.
Mr Russell said the UK government had also made it clear that the document would be shared with the devolved administrations – but that it would need to be “handled confidentially”.
However, in a letter to his UK government counterpart, David Davis, Mr Russell said the Scottish government would release the information to the public even if it is asked not to do so.
Mr Russell argued that people “have a right to know the impact on jobs and living standards of the UK government’s decision to pursue the UK’s exit from the EU”.
He added: “Further, this is not our analysis and we do not see it as our responsibility to make arrangements on confidential handling.
“I want to be clear that if you send the analysis to us we will make it public”.
The leaked study suggests that in three different scenarios the UK economy would grow more slowly than it would if it stayed in the European Union.
The government has argued that the document is incomplete, and that immediate publication could damage UK negotiations with the EU.
Theresa May initially told reporters en route to China, where she is on a trade mission, that making the analysis public before it was fully completed would be “wrong”.
But with the government facing potential defeat in the vote on Wednesday afternoon, Brexit minister Robin Walker told MPs a copy of the report would be given to Hilary Benn, the Labour chairman of the Commons Brexit committee.
He added: “And a confidential reading room can be provided for other MPs and peers a copy of this analysis to view the material on a confidential basis. This will happen only when arrangements can be made.”
Mr Russell’s letter was published ahead of new UK Cabinet Office minister David Lidington arriving in Edinburgh for talks with Scottish government ministers about Brexit.
Mr Russell and Deputy First Minister John Swinney will set out their concerns over devolved powers and Brexit legislation.
The Scottish parliament will not put forward the EU Withdrawal Bill for a consent vote until the row is resolved.
Mr Lidington said it was important the two governments worked together “to find an agreed way forward”.
But Scottish ministers warned that there was “currently no prospect of the Scottish Parliament giving its consent” to the Withdrawal Bill.
The UK government and the devolved administrations are at loggerheads over what happens to powers currently not reserved to Westminster, but which are currently exercised from Brussels, when the UK leaves the EU.
Ran out of time
The current proposals in the EU Withdrawal Bill would see all powers return to London before some are fully devolved and others are integrated into UK-wide frameworks, but the Edinburgh and Cardiff administrations term this a “power grab”.
UK ministers had pledged to amend the legislation to assuage these concerns, but ran out of time to do so while the bill was under consideration in the Commons.
They now say it will be amended in the Lords, but the devolved administrations have started work on their own stop-gap legislation in preparation for a scenario where consent for the Withdrawal Bill is withheld.
Mr Lidington is taking on the role of Damian Green, his predecessor as Cabinet Office minister who led for the UK government in negotiations with the devolved administrations.
He is visiting Cardiff and Edinburgh in this role for the first time on Thursday.
