Powers of Holyrood under attack from Brexit Tories - warns Sturgeon

Nicola Sturgeon is to accuse the UK Government of using Brexit to launch an attack on the very foundations'' of devolution.

Scotland's First Minister will warn the powers of the Scottish Parliament are at risk from the Conservative Government at Westminster following the vote to leave the European Union.

In an address to the David Hume Institute in Edinburgh, Ms Sturgeon will say that after 20 years of progress, devolution now faces a grave threat''.

Citing the majority vote in Scotland to remain in the EU and efforts to reach a compromise with the UK Government on Scotland's future place in Europe, she is expected to say: The democratic deficit which fuelled the demand for a Scottish Parliament in the 1980s and 1990s has opened up again.

The Brexit process has emboldened a now powerful Westminster faction, which never accepted devolution, and which now sees it as an opportunity to rein in the Scottish Parliament.

In place of a multinational United Kingdom democracy, they see Brexit as the way to claw back ground.''

Ms Sturgeon will say that despite promises made by the Leave campaign during the referendum that Holyrood would gain new powers repatriated from Brussels, statements suggest elements of farming and fishing policy now risk being taken back to Westminster''.

She will say: That would be utterly unacceptable. It would be a gross betrayal of the claims and promises made during the EU referendum campaign.

And more profoundly it would fundamentally undermine the basis of the existing devolution settlement.

So what we have is in effect an attack on the very foundations of the devolved parliament we voted for 20 years ago.

It is being made by a UK Government which speaks the language of partnership but which in reality pays scant if any heed to Scotland's democratic voice.''

Ms Sturgeon has said a second referendum on Scottish independence would be the result of ''sheer intransigence'' on the part of the UK Government, and that her party has a ''cast-iron mandate'' to call another vote, justified by both the EU referendum result and the SNP's victory in last May's Holyrood election.

She will add: The UK Government still has an opportunity to change course before it triggers the Article 50 process. I very much hope it does.

However if it doesn't, it will show that the democratic deficit which people voted to end in 1997 doesn't just endure - it continues to cause harm to Scotland's interests, to our international relationships, to our very sense of our own identity.

And so if those circumstances arise, proposing a further decision on independence wouldn't simply be legitimate, it would almost be a necessary way of giving the people of Scotland a say in our own future direction.

It would offer Scotland a proper choice on whether or not to be part of a post Brexit UK - a UK that is undoubtedly on a fundamentally different path today than that envisaged in 2014.

And in the absence of compromise from the UK Government, it may offer the only way in which our voice can be heard, our interests protected, and our values upheld.''
