The main impact is to transfer significant power to MPs to determine what kind of Brexit or no-Brexit the United Kingdom will have because - as and when - Theresa May loses the vote on her Brexit plan next week, she will have to report to parliament in three working days on what comes next.
And Labour's shadow Brexit secretary Sir Keir Starmer suggested that the continued uncertainty meant an extension of the Article 50 process, delaying the formal date of European Union withdrawal beyond March 29, "may now be inevitable".
UK Brexit minister Martin Callanan ruled out that prospect and said May would update MPs on Wednesday about the assurances over the backstop she is seeking from the EU.
The setback for the government came after a day in which senior ministers spoke out about the risks of exiting the European Union without any form of withdrawal agreement.
By 308 to 297 votes MPs demanded that the government produces its alternative plans within three working days if her deal is voted down on 15 January.
The Speaker denied Francois's claim he was "overriding" a motion of the Commons by allowing the amendment, prompting the Tory backbencher to claim Bercow was engaging in "sophistry".
"The amendment doesn't affect the normal operations of the Treasury. but it does make it harder for the government to drift into no deal without parliament being able to direct it", Yvette Cooper, the MP who introduced the amendment, told the Guardian.
Combined with a vote late yesterday when the government lost on the finance bill, the defeats underline May's precarious position in Parliament and the hard she will have in winning approval for her Brexit deal.

So at that point MPs could - at last, some would say - vote on what form of Brexit or no-Brexit (via a referendum) they would support.
"We are doing everything we can to win the meaningful vote that happens on Tuesday", the spokesperson said.
He told MPs: "There is a question of extension of Article 50 and that may be inevitable now given the position we are in".
The Commons amendment, tabled by Labour's Yvette Cooper, is created to limit the Treasury's ability to spend money on no-deal preparations, without the explicit consent of Parliament.
Ian Murray, the Labour MP for Edinburgh South and a leading supporter of the People's Vote campaign, said: "The threat of a no deal Brexit has cynically used by the government for many months as part of their campaign to bully and intimidate Parliament into voting for a bad deal that would leave us worse off and offers less control. I think what's important is that if we are to secure assurances, MPs are aware of what they are before the vote takes place", a Downing Street spokesman said.
The suggestions did little to win over the DUP. Wilson, one of 10 DUP lawmakers propping up May's minority government, described her deal as "ruinous".
"I don't think that the British public are served by fantasies about magical alternative deals that are somehow going to sort of spring out of a cupboard in Brussels", Lidington told the BBC.
The government needs 318 votes to get a deal through the 650-seat House of Commons, as seven members of Irish nationalist party Sinn Fein do not sit, four Speakers and deputy Speakers do not vote, and the four tellers are not counted. But there is little indication that many MPs have been swayed and the deal is nearly certain to be defeated on Tuesday. Ms.
