Scottish ministers will call for increased powers during talks in Edinburgh on Wednesday, after again threatening to ax the U.K. government's Repeal Bill, local media reported.

U.K. First Secretary of State Damian Green and Secretary of State for Scotland David Mundell are set to meet with Scottish Deputy First Minister John Swinney and Scotland's Brexit minister, Michael Russell, to discuss what powers Holyrood will gain after Brexit.

The British government's plan to convert the vast majority of EU law and regulation into English law — known as the European Union (Withdrawal) Bill, or Repeal Bill — was met with intense criticism from the devolved governments of Scotland and Wales when it was presented in July.

Nicola Sturgeon, the Scottish first minister and leader of the Scottish National Party, and Welsh First Minister Carwyn Jones said the Repeal Bill was “a naked power-grab” that returned EU powers to Westminster instead of sharing them with Scotland and Wales.

In a statement prior to Wednesday's meeting, Russell reiterated that both the Scottish and Welsh governments would withhold consent to the Repeal Bill in its current form and said he would make clear that changes must be made to protect devolution.

“The bill — as it currently stands — means that Westminster would take exclusive control over significant areas of devolved policy, such as support for Scotland’s farmers and food producers and many aspects of environmental protection and control of our seas,” he said.

“We know that the U.K. government has its eye on more than 100 policy areas. That is a direct threat to the devolution settlement which the people of Scotland overwhelmingly voted for in 1997.”

Russell added that Holyrood is not opposed in principle to U.K.-wide frameworks in certain areas, but that must be "on the basis of agreement among equals, not imposed by Westminster."

Green, the U.K. first secretary of state, said the meeting showed the government's "commitment to progressing discussions."

“In some areas there will need to be a common approach," he said. "There will be other areas where I intend that the Scottish and U.K. governments can make progress in identifying policy areas that could be released to Holyrood under the new legislative arrangements."

“We expect there will be a significant increase in the decision-making power of each devolved administration and we want to address this in a way which delivers certainty and continuity for people and businesses across the U.K.”

In the June 2016 Brexit vote, Scotland overwhelmingly voted to remain in the EU. In an open letter in July, over 60 prominent figures from Scottish civil society urged the U.K. to reverse course on Brexit altogether.
