AS it stands, the UK Government’s EU Withdrawal Bill poses a huge threat to Scotland’s devolved powers – and it could spark a constitutional crisis.

The debate centres on clause 11 of the Bill, which sets out which parliament certain devolved powers will return to post-Brexit.

The UK Tories have been slammed for their attempts at a “power grab”, and the Scottish Government has said it will refuse consent for the Bill unless there are changes.

Deputy First Minister John Swinney and Brexit Minister Mike Russell have lodged a legislative consent memorandum in the Scottish Parliament, which will set out Scotland’s position on the UK proposals.

The next two weeks will be crucial, leading up to a final debate and vote – and here’s the timeline.

Tuesday, May 1

Holyrood’s Delegated Powers and Law Reform Committee took evidence from Scottish Brexit minister Russell.

Wednesday, May 2

Russell will again be addressing a committee, but this time the Finance and Constitution Committee at 10am.

Thursday, May 3

This date is one for your diaries. At 9.30am, the Finance and Constitution Committee will be taking evidence from David Mundell, Secretary of State for Scotland, and Chloe Smith, Minister for the Constitution.

Week of May 7

The Finance and Constitution Committee, the lead committee on the bill, will publish its report for the Scottish Parliament – it will be ready by Friday, May 11 at the latest.

Monday, May 14

The Scottish Government motion, recommending either consent or refusal for the UK bill, will be lodged no later than 10am on May 14.

Tuesday, May 15

If the EU Withdrawal Bill progresses as expected in the Lords, the legislative consent motion will be debated in Holyrood on Tuesday, May 15, before the third reading in the House of Lords.

Wednesday, May 16

This will be the final date for the Scottish Parliament to indicate consent – or otherwise – to Westminster, before the bill completes its finals stages in the House of Lords.

The bill will then pass between the Lords and the Commons, but no new major amendments can be made.
