The Liberal Democrats' amendment would, similarly, force the government to rule out a no-deal exit, but it would also instruct the Cabinet to set up another Brexit referendum. What that basically means is that if there isn't anything else but the Brady Amendment being approved, we're still nowhere near getting a deal done before 29 March.
If Labour whips its support, May's minority administration will need most of its own rebels to fall into line while hoping that Labour MPs who are concerned at being accused by voters of frustrating Brexit will abstain or vote with the government.
"This Withdrawal Agreement has been agreed with the United Kingdom government, is endorsed by leaders, and is not open for renegotiation", the European Commission spokesman told the journalists.
The committee's decision - adopted unanimously with 53 votes in favour - must be endorsed by the full parliament next month, which is likely as other European Union institutions have backed a move to relaxed visa requirements for Britain after Brexit, provided London reciprocates.
Nearly all of Wales' 28 Labour MPs - with the exception of Paul Flynn who has not been attending Parliament - voted against a no-deal Brexit and against Sir Graham's amendment.
May insists her agreement can still win Parliament's backing, if it is tweaked to alleviate concerns about a contentious Irish border provision.
The small Northern Irish Party which props up May's minority government but opposes her deal, said the contents of May's speech to lawmakers on Tuesday will determine whether it will support the amendment. It would tie Northern Ireland with the European Union and keep the rest of Britain in a customs arrangement to provide for the free movement of goods.
"The House of Commons will have to vote again mid-February on Plan C. And it will have to be Plan A all over again but with even more pressure of no-deal Brexit looming".
"She (May) is taking a risky task going back to Brussels to renegotiate", said Joseph Trevisani, a senior analyst at FX Street in NY.

Maurizio Sarri issues update on Eden Hazard’s Chelsea FC future

Doncic gets his 2nd Triple-Double, Raptors beat Mavericks 123-120
Doncic's three-pointer made it 104-99 before the Raptors made their charge to grab the much-needed victory. "We didn't get a win". He is the first teenager, and the youngest player in league history, to notch a 30-point triple-double.
Weber said: "If there is now a unilateral attempt to reopen the agreement, the outcome will be that not just the backstop has to be renegotiated - then the Gibraltar question, the question of how much money Britain has to pay for exiting, the question of citizens' rights will have to be renegotiated".
She will open Tuesday's debate in the Commons by setting out the government's backing for an amendment tabled by senior Tory backbencher Graham Brady, which seeks to replace the Irish backstop with "alternative arrangements".
The report said MPs "must" be given the chance to vote on extending Article 50, delaying the UK's exit from the bloc to stave off leaving without an agreement.
"While the European Union might agree to side deals to mitigate the worst of the disruption of a no deal outcome, this can not be guaranteed, and we are concerned by the extent to which assumptions of an ongoing cooperative relationship underpin the government's no deal planning".
Not all amendments will be put to a vote, with Commons Speaker John Bercow to make the selection on Tuesday morning, with votes cast from 7:00 pm (1900 GMT).
She also invited party leaders to further talks about what would be needed to get a deal through Parliament.
The PM said she would go back to Brussels to get a "significant and legally binding change" to the controversial proposal, which aims to stop the return of border checks.
Speaking to RTÉ in London, David Cullinane said: "If there is a hard border, that will come about because of chaos in Westminster, not because of anything Irish politicians have done".
She said there appeared to be a lack of "ownership" in Britain of the agreement struck between the two sides in November, and that there was insufficient transparency in the prime minister's moves.
