Adam Tomkins said Ms Sturgeon had reined in her Brexit ministerCredit:PA Nicola Sturgeon has been accused of “scaremongering” after she claimed UK Government proposals to resolve the dispute over post-Brexit powers would “completely demolish” the principle of the devolution settlement.The Scottish Conservatives said it was “sad” to see the First Minister reduced to such tactics and accused her of “taking the reins” from Michael Russell, her Brexit minister, after he said an agreement was still “perfectly possible”.He claimed there was not much separating the two sides, while she was warning in a newspaper article of the danger of a future Tory government ripping up flagship Holyrood legislation.Adam Tomkins, Conservative spokesman on the constitution, said Mr Russell’s comments flew in the face of Ms Sturgeon’s scaremongering and highlighted “clear divisions in the SNP”.He added: “There is an entrenched position from Nicola Sturgeon and it’s obvious she has taken the reins. She should let her government agree a Brexit deal which works for Scotland and get on with her day job.”The Welsh government struck a deal last week while Ms Sturgeon insisted changes to the Brexit bill did not go far enough. Despite her stark warnings, Lord Hope of Craighead, formerly Scotland’s most senior judge, said the amended EU Withdrawal Bill came “very close” to respecting the devolution settlement and a deal was within reach. But Ms Sturgeon said the definition of “consent” in the amendment was “surreal and perverse” as it meant legislation would be deemed to be the subject of a “consent decision” whether Holyrood voted for or against a motion. The convener of cross-bench peers in the Lords will table further amendments on Monday in the hope of reaching an 11th hour deal.Ahead of further talks later this week, Ms Sturgeon wrote in the Sunday Herald: “After Brexit, the UK Government has made clear it wants the final say on many devolved policy areas which are currently subject to EU law – completely demolishing the principle at the heart of the devolution settlement endorsed democratically by the people of Scotland more than 20 years ago.”The Tories have now proposed amendments to the Bill which they say take account of our concerns. But, as ever, the devil is in the detail, and a careful reading of the small print betrays the reality of what we are being offered.”New amendments from the UK Government will introduce a “sunset clause” so that devolved powers returning to Westminster – in order to create common frameworks across the UK – do not stay there indefinitely.They also introduce a requirement for a “consent decision” at Holyrood before ministers can legislate in devolved areas. Mr Russell told the BBC’ Sunday Politics Scotland programme that was not “tolerable” and insisted that he and the First Minister were “singing from the same hymn sheet”.But he also said a deal could be done and said he would consider Lord Hope’s amendments.He added: “If these amendments are as positive and hopeful as I think they probably will be, then once I have seen them I’m happy to comment on them and I hope I can be very positive about them.”I don’t think there is a huge amount that separates us now. The issue is very, very clear – if we resolve that issue (of consent) there will be a deal.”A spokesman for the UK Government said it hoped the Scottish Government would sign up to the “sensible and pragmatic” compromise supported by the Welsh administration.
