This is the sensational moment every SNP MP walked out of the Commons during Prime Ministers Questions.

SNP group leader Ian Blackford refused to resume his seat after being denied a request for the house to sit in private.

Blackford had initially stated: "The Prime Minister gave a commitment that she would treat Scotland as part of the union of equals. Yet last night, she pressed ahead with a power grab in direct opposition to Scotland's elected Parliament.

"The PM silenced Scotland's voice. Having broken constitutional convention and plunged Scotland into a constitutional crisis, will the Prime Minister now commit to bringing forward emergency legislation so that the will of the Scottish Parliament can be heard and, more importantly, respected?"

However, May responded: "We do expect that the outcome of the whole Brexit is a significant increase in the decision making power of Holyrood."

Blackford replied: "The reality of the situation is that powers enshrined under the Scotland Act in 1998 are being grabbed back by this Parliament. It is a power grab and the MPs from Scotland were not given even the courtesy of debating it last night. It is a democratic outrage.

"The people of Scotland will not be disrespected by this Parliament."

Blackford concluded: "I have no options but to ask that this house now sits in private."

Bercow refused his request.

Blackford attempted to raise a point again, which Bercow would not allow, resulting in the Speaker of the House telling Blackford to leave.

He did, followed by the rest of the SNP MPs.
