THE UK Government and Labour pushed Scotland to the sidelines as Westminster voted through a power grab on Holyrood.

On a crunch day for the UK Government's EU Withdrawal Bill in the House of Commons, archaic procedures saw most of the day spent voting on Lords amendments with little time spent on debate.

Discussion of the Brexit power grab on Scotland, via Clause 15 of the EU Withdrawal Bill, was left with just 15 minutes at the end of proceedings.

Filibustering by UK Government minister David Lidington meant no other speeches were made during that time.

The final group of Lords amendments were defeated by 321 votes to 40, with the SNP voting against and Labour abstaining.

SNP Westminster leader Ian Blackford said Labour had "let down the people of Scotland".

The result means the constitutional crisis sparked by Holyrood's refusal to grant consent to the Brexit bill – a position backed by all Scottish parties but the Tories – continues.

Scottish Brexit minister Mike Russell said: “For almost 20 years, decisions made by the Scottish Parliament on issues affecting devolution have been final.

"Today, the UK Government tore up the constitutional rule-book and imposed its will in the face of an overwhelming vote in the Scottish Parliament.

"The fact that they rail-roaded this measure through with no time for speeches from anyone other than the UK Government Minister shows utter contempt for Scottish democracy. This is a dark day for devolution.

"Forcing through a law that could freeze the powers of the Parliament for up to seven years without its consent, means our hands will be tied in relation to farming, fishing, the environment, food standards and a host of other devolved areas.

"The UK Government today had a duty to amend the bill to respect the will of the Scottish Parliament. They failed to do so. Further Brexit bills will also require the consent of the Scottish Parliament – and yet the UK Government has decided to use this moment to tear up the rules that have until now protected devolution.

"We will reflect on this situation carefully as we consider next steps.”

Scottish Labour MP Ian Murray defended his party's decision to abstain on Twitter.

He tweeted: "B4 the SNP start jumping up & down. This is Lords ping pong & if we were to defeat the government on the compromise amendment from the Lords it would revert back to the unamended clause which everyone, including the Tories, thought was deficient. Ping pong is take it or lose it."

There were reports from MPs including Carol Monaghan that after Blackford raised a point of order asking what Scottish MPs could do to ensure proper debate, Tory Ian Liddell-Grainger shouted "suicide".

Monaghan said: "This complete contempt is what the Scottish people are up against."

Scottish Secretary David Mundell, in a statement outside the House, said the Bill "fully respects both the spirit and letter" of the devolution settlement.

He went on: "It guarantees the vast majority of powers returning from the UK will go directly to Edinburgh, Cardiff and Belfast. In a small number of areas, current arrangements will remain in place until we can create new UK-wide frameworks."

Speaker John Bercow took points of order from SNP, Labour and Tory MPs for more than 50 minutes after the votes on the devolution and Northern Ireland amendments.
