There is nothing to stop the government bringing back the same deal again and again to the House of Commons until either MPs accept it, or seek to oust May, who faces a no-confidence vote on Wednesday called by the opposition Labour Party.
She is expected to do so - Conservative MPs and Tory allies the DUP are highly unlikely to join Labour in voting against her and the Government. Instead, potential outcomes of a no vote include a no-deal Brexit on March 29, an extension of that deadline, or a general election or a second referendum.
"If a deal is impossible, and no one wants a deal, then who will finally have the courage to say what the only positive solution is?" he tweeted.
A major issue in the pre-Brexit wrangling has been around the border between Northern Ireland and the Republic of Ireland. To implement the agreement, a slew of domestic legislation has to pass both houses of Parliament before being signed into law.
The first step would be to extend the U.K.'s departure date, although European Union diplomats warn this would only be for a few months.
ANALYST'S TAKE: "With a lack of an option B, the vote could narrow down the possibility to a hard-Brexit or a no-Brexit that could be the next step for the timed Brexit journey", Jingyi Pan of IG said in a market commentary.
The Northern Irish DUP have said they will vote against Labour leader Jeremy Corbyn's motion, which is created to trigger an election.

But what time is the crucial vote, what is the contentious "Irish backstop" and what will happen if there is a "no deal" Brexit? "What we're seeing from British public is Brexit fatigue".
"It's now up to the British government to say what the next stage is". May also - crucially - has protection from her own side: After a failed no-confidence vote in her leadership last month, she can't be challenged as party leader for a year.
"Right now it's too early to assess all the consequences of this vote", he told MEPs, adding that those opposed to the deal had "very different, very diverse, sometimes opposed or even contradictory motivations".
The new Burnley hub will introduce more automation to the operational equation, promising efficiency gains that could act as a cushion for margins should Brexit uncertainty continue to dog the sector this year. In her final appeal to lawmakers before the vote, she insisted that the withdrawal agreement - the legally binding treaty put to Parliament - would remain part of any orderly Brexit.
May will likely head back to Brussels to plead with European Union leaders to offer her more favourable terms. "No such alternative deal exists". It only comes into effect if the two sides are unable to negotiate a new trade agreement by the end of 2020. No one else in her party seems eager to drink from this poisoned chalice, and most will also be reluctant to risk a new national election they would be likely to lose. Mr. Corbyn rose to his feet after Tuesday's vote to drive home his point.
The government must set out what happens next by Monday, if - as is expected - it survives the no-confidence vote.
"The fireworks will happen after today - when it is clear what happens next", she said, predicting that a decision not to leave the European Union would send sterling shooting up while a no-deal Brexit would send it down to record lows.
The BFC said it can not emphasize strongly enough that a no-deal Brexit "is a scenario that should be avoided at all costs".
May had argued that rejecting the agreement would lead either to a reversal of Brexit - overturning voters' decision in the 2016 referendum - or to Britain leaving the bloc without a deal. Professor Grant, on the other hand, believes that to extend the negotiation process is the only way forward considering that, at present, the British Parliament is in complete disarray over the issue.
