New Environment Secretary Michael Gove ruled out the Scottish Government having a direct role in Brexit talks during a visit to Peterhead.
The Tory frontbencher rejected the idea as a non-starter despite growing pressure from the SNP for the Holyrood administration to have a seat at the table.
When pressed on whether the request could be accommodated, Aberdeen-raised Mr Gove said: “It can’t and doesn’t work that way.”
The former Aberdeen schoolboy and prominent Leave campaigner added: “The negotiations have to be controlled by the UK Government. It is working for the interests of the whole UK.”
He said the trip was part of his role to “spend as much time as possible listening to Scottish voters”.
But SNP Westminster leader Ian Blackford said the comments showed a lack of respect and urged the minister to “think again”.
Theresa May confirmed this week the UK Government’s repeal bill – to convert EU law into UK law – could require a legislative consent motion at Holyrood.
This is the mechanism by which a devolved body grants permission to the UK Parliament to pass a law in a devolved area, but it is not a veto as the Scottish Parliament can be overruled by Westminster.
However, failure to obtain the backing of MSPs would set up a potentially disruptive constitutional clash and the SNP has indicated it could demand a seat at the Brexit negotiations as its price for ensuring smooth passage.
Mr Blackford confirmed yesterday the party is seeking a “direct voice”, insisting involvement in the Joint Ministerial Committee process was not adequate representation.
He said: “It’s a parliament of minorities and there ought to be respect for the devolved institutions.
“It’s disappointing Michael Gove is speaking in the way he has done.
“He has got to think again.”
