As Prime Minister Theresa May battles to drum up support for her Brexit deal, her government was found in contempt of Parliament on Tuesday over its refusal to release Brexit legal advice from the Attorney General.
Six opposition parties - including the DUP - teamed up on Monday night to ask the Speaker John Bercow to start contempt proceedings against ministers for withholding Brexit legal advice.
The British government said they will published the "final and full" advice on Wednesday.
British Prime Minister Theresa May is putting the fate of her Brexit deal in Parliament's hands, saying lawmakers must back it to deliver on voters' 2016 decision to leave the European Union and "create a new role for our country in the world".
Opening five days of debate on the Brexit deal, May told Parliament that the British people had voted in 2016 to leave the European Union, and it was the "duty of this Parliament to deliver on the result" of the referendum.
The debate is likely to affect the upcoming parliamentary vote.
Mr Brake told BBC Radio 4's Today programme: "Clearly the Attorney General is the one who came to present the government's case for not releasing this and I suppose he is in line for being in contempt, and I think the house should consider suspending him for that action".
"The motion makes clear the government must now publish the attorney general's final legal advice in full", Starmer said.
This is a far greater concern for No 10 than sanctioning of the government or a minister for contempt, which helps explain why the prime minister has deployed leading Brexiteers Mr Cox and Michael Gove, the environment secretary, in the past two days to try and sell her imperfect deal to Brexiteer MPs.
The opposition Labour Party, which pushed for the vote, was jubilant.
In reality, the vote was about putting pressure on a weakened Government. The vote is scheduled for December 11th with days of Parliamentary discussions prior scheduled to begin later Today.
Defeat would leave the United Kingdom facing a chaotic "no-deal" Brexit on March 29 and could topple the prime minister, her government, or both.
MPs have voted for an amendment that will ensure MPs can vote in favour of a "plan B" option in January if Theresa May's EU Withdrawal Agreement gets voted down.
Mr Cox gave Parliament an outline of his legal advice to the Government on Monday.
After the vote, the British pound fell to its lowest against the U.S. dollar since mid-August.
