THE SNP has issued a fresh call for the Brexit Secretary to appear before Holyrood after accusing UK ministers of "tearing up" the devolution settlement.

The party wants David Davis to face MSPs on the Scottish Parliament's Europe Committee amid a row over the UK Government's handling of the EU Withdrawal Bill.

Mr Davis has been asked to give evidence to the committee on several occasions, but is yet to do so.

The SNP was left outraged last week when amendments to the legislation affecting Scotland were passed after less than 20 minutes of debate in the House of Commons.

The Scottish Parliament had already voted against granting formal consent to the Bill.

The SNP said the move effectively turned "on its head" the Sewel convention, the precedent that Westminster must have the consent of Holyrood to legislate on devolved matters, and called for Scottish Secretary David Mundell to resign.

The opposition to the legislation stems from concerns Holyrood's powers could be constrained as a result of the legislation, with some of the responsibilities returning from Brussels going to UK ministers instead of those in Edinburgh.

SNP MSP and Europe Committee member Mairi Gougeon said: "The Tories are tearing up the devolution settlement before our eyes. But we cannot allow them to get away with it.

"It's now abundantly clear that David Mundell has failed Scotland in the Cabinet, and people have seen through his excuses and bluster.

"It's now imperative that the UK government explains how it will navigate the unfolding constitutional crisis, and it's clear that the Secretary of State for Scotland isn't up to that job.

"David Davis, the man behind Westminster's Brexit agenda and its severe implications for Scotland, has many questions to answer."
