The House of Commons descended into chaos as the SNP Westminster leader Ian Blackford was expelled for trying to call a stunt vote in the middle of PMQs.
The Speaker of the House John Bercow repeatedly told Ian Blackford to sit down but he refused.
The SNP has described this as a "democratic outrage" and claimed that Scotland's voice is being silenced while UK Government ministers carried out a "power grab".
"My job, my colleagues' job is to stand up for the powers of the Scottish Parliament".
He made the weird and telling claim that 'even if we'd had 100 hours of debate, the situation wouldn't have changed, ' proving the United Kingdom government's contempt for Scottish devolution and desire to rollback the powers of the devolved parliament.
Many are also furious Scottish MPs were given minutes to discuss key Lords amendments on Tuesday night. Yet last night she pressed ahead with a power grab in direct opposition to our elected parliament.
"I really do hope that the people of Scotland listened very carefully to what the PM said", he said.
Earlier Bercow completely lost control of the Commons as the SNP raged about the cutting short of a debate on devolution last night.

"It is a democratic outrage".
Mr Blackford tried to use an arcane procedure demanding the "House sit in private" - a motion that requires a vote of MPs on whether to clear public galleries.
The unprecedented event brought PMQs to a temporary halt as Mr Bercow refused his demands.
The party's Westminster leader was then followed by all other SNP MPs. Such a complex endeavour is bound to complicate the agenda of Prime Minister Theresa May as she tries to negotiate Brexit. But Scotland's devolved parliament, Holyrood, had rejected those measures last month with the backing of all parties save the Scottish Conservatives.
Bercow said: 'I must just say to the House, that I am most grateful to the Prime Minister and before we come to points of order, that for all the turbulence and discord of today's proceedings the little baby who has been observing them has been a model of impeccable behaviour from start to finish'. The SNP calls it a "power grab", something the United Kingdom government denies.
The Scottish First Minister added: "The decision to act without our consent, and the manner of doing it, will not be forgotten".
Lawmakers from the Scottish National Party (SNP) walked out of the British parliament on Wednesday to protest what they say is Scotland's voice being ignored over Brexit.
