The pressure is increasing for Theresa May to release documents related to the Brexit, with Tory Brexiteer Jacob Rees-Mogg, who chairs the Eurosceptic European Research Group (ERG), suggesting that the information should be "certainly made available" to the ministers of the Cabinet to make sure you know what they are recording.
His appeals were followed yesterday by Michael Gove Secretary of the Environment.
But health secretary Matt Hancock rejected requests for a legal opinion and said that a decision to that effect would be taken only under "exceptional circumstances" by the prime minister.
He said attorney general Geoffrey Cox, the government's chief legal advisor, could answer questions in the Commons.
Theresa May and Jacob Rees-Mogg
It can answer questions in the Commons but it is not normal to publish legal advice
Legal advice is usually reserved and Hancock said: "We have a brilliant attorney general who sets out the legal position.
"You can answer questions in the Commons but it is not normal to publish legal advice.
"This is a decision in exceptional circumstances for the Prime Minister."
Rees-Mogg said he was more worried about the fact that the agreement is good or bad rather than all parliamentarians who see such advice, while expressing wider concerns about the government being "rebounded" in decisions on Brexit.
Ms. May's minority government allies the DUP and Brexiteer parliamentarians, including the Secretary of the environment Michael Gove, are among those who want to see full legal advice on how to end any customs agreement to avoid a tough Irish border to prevent it becoming a permanent solution.
A vote by the Commons could be forced when Parliament returns after its mini-recession in November, which would further increase pressure on the Prime Minister – who is now traveling to Belgium to attend a working dinner with NATO leaders.

He warned that by the middle of the century, Germany would be the only European country with an economy big enough to sit in the full G8 group.
He said that European countries must work together to defend their values and their way of life against alternative models presented by emerging powers like China.
He said at the event: "We must strongly defend and promote our European model.
"If we do not write the rules of the game, China will write them for us.We want a Europe that offers opportunities for all – a renewed social market economy".
"We all have to fight against those who want to demolish Europe with their fear, their populist deception, their attacks on the European project.
"Now there is a Farage in every country".

David Davis wants the government to publish his legal advice
Update 8.59: Davis requires full disclosure of legal advice
The former Brexit secretary David Davis said that the full legal opinions of the government on Brexit should be published.
He told BBC Today's Radio 4 program: "What we need to see is complete legal advice, not a summary."
Mr Davis said that the parliamentarians must know how the Irish blockade works.
He said: "Will we have to wait until the Irish government says it's OK to leave? If so, it's not acceptable."
"Will we have to wait until it is convenient for the European Commission to say when we leave? If so, it is not acceptable.
"I suspect that they have not blocked any of these problems and that they should be blocked before Parliament's vote".
Davis said the government was not "willing to take any risk" to test the EU's negotiating position, except for the exit account.
Leaving without an agreement would mean some "hiccups in the first year", but the United Kingdom would have "all rights and controls over its own destiny".
Davis said there would be insulin and that the lack of food would be "absurd".
He said: "We are a great country, we can take care of ourselves".
