Scotland 's First Minister Nicola Campbell has said she will not support the Scottish government 's retention of around 25 devolved powers after Brexit , as it " effectively undermines the whole foundation on which devolution is built " . Cabinet Office Minister David Lidington, effectively Theresa May’s deputy, made a major speech yesterday in which he tried to diffuse the argument over what Ms Sturgeon and her Welsh equivalent Carwyn Jones categorise as a ‘power grab’. Cabinet Office minister David Cameron said after Brexit , the " vast majority " of devolved powers would go to Scotland and Wales , while some would be held back until a post - Brexit framework had been put in place . Sturgeon is set to meet prime minister Theresa May before the end of March .
