The UK Parliament ordered the government to reveal the advice, and the government complied after it lost a crucial vote in the Commons on Tuesday, in what was called a political humiliation for Prime Minister Theresa May.

Meanwhile, British MPs entered the second day of a five-day marathon debate over the agreement signed with the European Union, which needs to be ratified by Parliament with a majority for it to go through to the next stage in time for Britain's formal exit from the European Union on March 29, 2019.

Are they still nailing their colours to the mast?

A group of 30 constituencies backed no deal, while only two chose the deal the Prime Minister has put before parliament.

He placed a 10 per cent probability on a no-deal Brexit, down from 20 per cent, and a 50 per cent probability on an orderly Brexit, down from 60 per cent. This deal offers a sensible compromise that protects our economy but delivers on the decision of the British people in the referendum. If...

"We have therefore been left with no option but to write to the speaker of the House of Commons to ask him to launch proceedings of contempt", Labour's Brexit spokesman Keir Starmer said.

Chancellor of the Exchequer Philip Hammond tells lawmakers who believe May can go back and renegotiate her deal with the European Union that they are out of tune with reality.

That help, in the form of new clarifications of how the deal would work or perhaps even small tweaks to agreed text, will not convince the massed ranks of May's opponents, who see the deal as either too much Brexit or too little.

"With this approach, instead of looking for which option is most people's first choice, you instead test which one beats all others in a head-to-head fight".

Mrs May is trying to get her deal approved by a Parliament that shows every sign of striking it down in a vote next Tuesday.

Islanders were in the majority with supporting a the deal when head to head with no deal and remain.

Mr Javid warned that "no matter how effectively" the government prepares for a no-deal Brexit, there would be "consequences" for the UK's security.

"Equally however I can not support a "no deal" proposition. The citizens' rights deal shouldn't be watered down as the United Kingdom has today proposed". "This has serious implications for the future of the country", he said.

May was set to face Labour leader Jeremy Corbyn at prime minister's questions at midday, before the Brexit debate got under way.

"There is no "one-size fits all" here, and there never will be".

"I want to see central to any agreement that we can control our own borders and that we can control our trade policies".

Dr Fox replied: "The Government will continue to make the case for what it believes is a balanced and reasonable agreement, but of course the Government will want to talk to members, it will want to look to ways to give a reassurance to the House wherever we're able to do that".

"The situation is incredibly divisive and clearly, there is no solution which will make everyone happy". I will support Theresa May as Prime Minister but I am seeking reassurances and expect the deal to change.

"What we need is calm and rationed reasoning and negotiating; not resignations or slanging matches". The Financial Times reported on Friday that leading "Leave" campaigners are also considering the possibility of a second vote.

Speaking recently, he said: "I'm absolutely diametrically opposed to it and I'm assured by a very large number of colleagues that they hold a similar opinion".
