Blackford then refused to sit back down and Bercow asked him to leave due to the "repeated and insistent refusal to resume his seat when so instructed" the Commons and not return for the rest of the day.
Conservatives accused Mr Blackford of orchestrating a publicity stunt because Mr Bercow had agreed to hear his motion for the House to sit in private - which would have required a vote and disrupted PMQs - at the end of the session instead.
The suspension prompted all SNP MPs to walk out of Commons chamber, pointing and jeering at Tory MPs.
This is the moment SNP MPs stormed out of the House of Commons partway through PMQs in protest after their Westminster leader was kicked out of the chamber.
Prime Minister's Questions was held up for more than five minutes as Mr Bercow scrambled to try and restore order.
Proceedings on the EU Withdrawal Bill last night were a democratic outrage and the Scottish Parliament must be respected.
'Under the circumstances, given the disrespect shown I have no option but to ask that this House now sits in private'.
Imagine being expelled for asking that Scotland's voice be heard. They pressed ahead in direct opposition to Scotland's elected Parliament. Yet the United Kingdom government proceeded to downgrade devolution and defy the Scottish people. This will haunt the Scottish Tories for a generation'. My mixed sequence of advice is that is better for the vote to be conducted at the conclusion of questions to the prime minister...
'The Tories haven't won a democratic mandate from the people of Scotland for over 60 years, yet they press on to claw back powers from Holyrood without consent.
This is a defining moment for all of us - if the United Kingdom government wants to change course, it must do so immediately by recognising and respecting the will of the Scottish Parliament, the Scottish Government and the Scottish people.
They think they can do anything to Scotland and get away with it.
'The SNP have played games with the constitution, played games with Brexit and now are playing games with Parliament.
The passing of the EU Withdrawal Bill meant powers which were supposed to return to the Scottish Parliament after the United Kingdom leaves the EU would go to Westminster for a period of seven years, a move which SNP MPs broke with the Sewel convention that changes to devolution would not occur without the consent of the Scottish Parliament.
Theresa May and her dysfunctional, weak government should be in no doubt - SNP MPs will abide by our duty and stand up for all our constituents and we will do it for a very simple reason.
