MPs have forced the government to agree to publish analysis comparing the economic impact of Theresa May's Brexit deal with remaining the European Union.
Before MPs vote on Ms May's Brexit deal, the government will have to publish an analysis comparing the impact of the proposed agreement with the consequences of the alternative scenarios of a no-deal Brexit and remaining in the EU.
The cross-party amendment was backed by more than 70 MPs from six political parties, including enough Tory rebels to deprive Ms May of her majority.
Facing a certain defeat in the Commons, ministers caved and agreed to accept the motion.

Theresa May faces defeat over plan to force release of economic analysis of her Brexit plans
Theresa May faces an embarrassing defeat over plans to force her into publishing data comparing Britain’s economic prospects under her Brexit deal to staying in the EU.
Eleven Conservatives – including Jo Johnson, who resigned as a minister last week – have publicly signed up to the cross-party push, with the rebellion set to grow if it comes to a vote on Monday.
The prime minister has so far refused to commit to releasing the analysis, which is likely to underline how remaining in the EU would deliver a more prosperous future for the country.
She said: "Coming out without a trade deal in March would lead to, frankly, quite a lot of disruption to businesses and jobs.
"Meanwhile the negotiation, the future political declaration, already sets freedom of movement comes to an end, the ECJ will not be our supreme court.
"We will be able to negotiate our own free trade deals around the world, everything that was promised in the Brexit referendum will be delivered in that future trade deal.
"I recognise it is not what's delivered in the withdrawal agreement, but Brexit is coming."
"I think the challenge now is for these Brexit dogmatists to show whether that is true.
"I think Theresa May deserves praise for her position. 'No deal is better than a bad deal' has disappeared. 'Any deal is better than no deal' is now the slogan. That is right.
"This deal that is now on the table is the best there is. There is no better deal for this crazy Brexit."

Threshold of 48 letters to trigger vote of no confidence in May not yet met, says Graham Brady
The threshold for challenging the prime minister has not yet been met, said the chairman of the committee in charge of Conservative Party leadership contests.
Sir Graham Brady said he had not received the 48 MPs’ letters needed to trigger a confidence vote that could see Theresa May removed as Tory leader.
More than 20 of the party’s MPs have said publicly they have submitted letters, but the exact number sent is not known.
Mr Clark suggested it could be extended for a matter of "weeks or months", saying: "If we were six weeks away from concluding a future economic partnership and agreeing that then it may make sense to extend the transition period."

Moderate Tories warn anti-EU 'purists' they could turn against Brexit if Theresa May's deal is torn down
Moderate Conservatives have warned they will push Britain towards tighter relations with the EU or even turn against Brexit altogether if “purists” in their party tear down Theresa May’s draft withdrawal deal.
A string of Tory MPs told The Independent that Eurosceptic colleagues who have begun a sustained push to bring down both Ms May and her Brexit plans, should not be mistaken that a no-deal exit risking the livelihoods of British people is obtainable.
The moderates say the only remaining option if Brexiteers block Ms May’s approach will mean being more closely bound to the single market or even revisiting the 2016 referendum result.

Jeremy Corbyn: I don't know how I would vote in second Brexit referendum
Jeremy Corbyn has said he does not know how he would vote in a new referendum on the UK’s membership of the European Union.
The Labour leader said he would need to know what the options are in any fresh test of public opinion as he reiterated his opposition to Theresa May’s Brexitagreement.
Mr Corbyn’s words came as Remain-supporting Labour MPs urged the leader to more solidly get behind a plan for a final say referendum, something which he said was an “option for the future”.

Irish PM Leo Varadkar says no to any further negotiations of Brexit deal
Irish prime minister Leo Varadkar has said no to any renegotiation with the British government over the Brexit withdrawal agreement.
His remarks come as Theresa May faces pressure to head back to the negotiating table in Brussels from MPs across the political spectrum, including Jeremy Corbyn, who insists there is still time to renegotiate rapidly.
Ministers in her own cabinet are also lobbying the prime minister to change course and seek further concessions from the EU or risk the deal falling in Parliament when Ms May asks MPs to vote on her plans next month.

Iran must stop using innocent British prisoners as political tools, Jeremy Hunt says ahead of official visit
Foreign secretary Jeremy Hunt is travelling to Iran today to hold talks on the fate of the country’s nuclear deal, Nazanin Zaghari-Ratcliffe – the British Iranian woman who has spent two and half years under imprisonment charged with spying in Tehran – and the coming peace talks aimed at ending the Yemen war.
Mr Hunt is the first western foreign minister to visit the country since Donald Trump unilaterally abandoned the deal and imposed sanctions on Iran and punitive penalties on foreign companies which continue to do business with Tehran.
The other signatories to the Joint Comprehensive Plan Of Action (JCPOA) – Britain, France, Germany, Russia and China – have repeatedly stressed that Iran is abiding by the agreement, as has the UN. The European Union is putting in place commercial mechanisms aimed at compensating firms which suffer from American penalties.
"Any prolongation of the transition period, which requires agreement with the British on their financial contribution during any such period, but, anyway it can't be indefinite, it has to be a fixed period of time."
He added: "I believe that we will make a final and specific proposal for these purposes during the course of this week.
"So, we would fix a final moment for up to which we can have a single prolongation of the transition.
"And, of course, this will all be by mutual agreement between the United Kingdom and the 27 member states."

Britain could stay tied to EU rules until after next general election under Theresa May's deal
The Brexit deal negotiated by Theresa May could see Britain tied to EU rules until after the next general election, under proposals being considered by negotiators.
The plans, discussed by EU27 ministers in Brussels on Monday, open the door to an incoming government reversing Brexit before the UK has fully left the bloc’s orbit.
Michel Barnier confirmed on Monday morning that EU leaders are in discussions about a one-time, fixed length extension to the transition period during which all EU rules continue to apply to Britain.
