Blackford attempted to raise a point again, which Bercow would not allow, resulting in the Speaker of the House telling Blackford to leave.
Most Scottish lawmakers are unhappy at a clause in the European Union withdrawal bill that temporarily restricts the Scottish, Northern Irish and Welsh assembly's powers, leaving them in the hands of the United Kingdom government while the rules governing Britain after Brexit are redrawn.
When Blackford refused to accept this, Bercow repeatedly told him to resume his seat, before calling for the party's Westminster leader to leave.

The SNP claim the EU Withdrawal Bill opens the door for a Westminster power grab which takes away from the Scottish Parliament and undermines devolution.

"The people of Scotland will not be disrespected by this parliament", he said.
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.
He insisted what had happened in the Commons was a "democratic outrage", adding: "Without debate, without the voices of Scottish MPs being heard, the government pushed through these amendments to rip out the powers from the Scottish Parliament".More news: Nebraska woman and her boyfriend charged with Sydney Loofe's murder
Blackford was followed by the rest of the SNP's 35 lawmakers.
The speaker of the house John Bercow MP appeared flustered and unprepared for the request, at first responding that it couldn't be heard, then stating that it could be, and finally deciding that it would only be heard at the end of Prime Minister's Questions. Such a complex endeavour is bound to complicate the agenda of Prime Minister Theresa May as she tries to negotiate Brexit. It leaves Holyrood exposed to having powers taken without consent in areas including trade deals, environmental standards and food safety, all issues of key concern to the Scottish parliament and all of which impact detrimentally on Scotland's economy - we're talking a loss of up to 80,000 jobs and cuts to wages of £2,000 a year, according to economists. Proceedings on the EU Withdrawal Bill last night were a democratic outrage and the Scottish Parliament must be respected.
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.More news: Kylian Mbappe breaks silence on injury scare ahead of World Cup
