HOLYROOD will have a vote on the Great Repeal Bill which delivers Brexit, Scottish Secretary David Mundell has said.

Mr Mundell said he was working on the basis that MSPs would vote on a legislative consent motion (LCM) in respect of the Bill, as it would affect devolved matters.

He also warned there would be “very serious consequences” if MSPs voted against the Bill, which will repeal the European Communities Act which took the UK into Europe in 1973.

Expected later this year, the Bill will embed EU laws into UK law at the point of Brexit so there is no ‘cliff edge’ transition, although these could be selectively repealed later.

As this week’s Supreme Court ruling underlined, Holyrood could not veto the Repeal Bill, as Westminster remains sovereign, and consultation with Holyrood is only a convention.

Nevertheless, if Westminster proceeded with the Bill regardless of rejection at Holyrood, it could lead to a constitutional crisis, as Westminster has never over-ruled Holyrood since the start of devolution in 1999.

Mr Mundell said: “I anticipate that, unlike the Article 50 notification, that the Great Repeal Bill would be the subject of the legislative consent process, and I’m working on that basis.

“It’s when the bill is published that you can give a definitive view.

“But given the Great Repeal Bill will impact on both the responsibilities of this parliament and on the responsibilities of the Scottish ministers, then I think it’s fair to anticipate that it would be the subject of a legislative consent process.”

Asked what would happen if Holyrood rejected the Repeal Bill, he said there had been predictions that MSPs would vote down the 2016 Scotland Act, and that hadn’t happened.

He said: “There are really big issues that will be in the great Repeal Bill.

“There will be issues around the powers for this parliament. And there will be issues around whether we have a hole in our law because the body of European law has not been adopted.

“Not agreeing to the Great Repeal Bill would have very significant consequences.

“But my focus will be to work with the parliament here, with the committees, indeed with the Scottish Government to get that agreement.”

Mr Mundell said the Great Repeal Bill could lead to another Scotland Act to set out the redistribution of powers repatriated from the EU - something the SNP would undoubtedly try to use to convert the Sewel Convention into consulting Holyrood into hard-and-fast law.

In contrast to the Great Repeal Bill, Mr Mundell said there should be no LCM on today’s EU withdrawal bill which empowers the UK government to trigger Article 50.

Nicola Sturgeon has promised an LCM on the issue, but Mr Mundell said the UK government disagreed, as the EU was a reserved matter.

He also cited the precedent of the UK Trade Union Bill in 2015, when SNP ministers wanted to introduce an LCM at Holyrood to block it, but the Presiding Officer refused to allow it.

If the current PO Ken Macintosh were to allow the Scottish Government to introduce an LCM without Westminster consent, it would be the first hostile LCM in Holyrood’s history.

Mr Mundell said: “I don’t hold the view that the bill we published this morning should be the subject of that process, because it is simply a notification that we wish to enter into negotiations to leave the EU, and that is a reserved matter.

“There was a ruling by the Presiding Officer I think in the previous parliament in relation to the Trade Union Bill that it was not a matter for the Scottish Parliament.

“These are matters for the Presiding Officer.

“We are very clear that we don’t believe that this notification requires legislative consent and we will not be pro-actively seeking it.”

Mr Mundell was speaking to the media after a meeting at Holyrood with SNP Finance Secretary Derek Mackay and Brexit minister Michael Russell.

On Wednesday, Mr Russell accused UK government ministers of lying about power-sharing arrangements between London and Edinburgh.

Mr Mundell said the meeting had been constructive and convivial, and added he had known Mr Russell for 20 years and was familiar with his “colourful language”.

He said the two governments had agreed their officials would work on the Scottish Government’s proposal to keep Scotland in the EU single market.

The UK government was ready to listen to the Scottish Government’s plans, but wanted Ms Sturgeon to take her threat of a second referendum “off the table”, he said.

“That issue is causing great uncertainty. It’s starting to impact on the Scottish economy. That’s the issue we want to take off the table.

“We’re quite happy to consider any considered proposals the Scottish Government bring forward. We want to be clear that any arguments for separate Scottish arrangements are driven by evidence and not by ideology.”

The First Minister’s official spokesman said the meeting had been “fairly pointless”, as Mr Mundell had provided “no detail whatsoever” about the repatriation of powers.

He said: “This [meeting] was a request by David Mundell, by the UK Government, ostensibly to discuss the repatriation of more powers.

“They provided no detail whatsoever on the issue they said they were keen to discuss. They provided zero, zilch, nothing.”

Mr Russell said he was “disappointed" by the meeting.

He said: “There was no offer, no guarantee even that current devolved powers, presently exercised through EU membership, will be coming back to Scotland. There should be no UK Government power grab.

“Time is running out for the UK Government to show it is serious about engaging with the Scottish Government’s compromise proposals to protect Scotland from the disaster of a hard Brexit.”
