It's either that, or a long delay to the country's exit from the EU.
Conservative lawmakers urged May against a long extension of the Brexit process in a letter sent after her exit deal was rejected for a third time by the House of Commons on Friday, a lawmaker said.
Britain has until April 12 to tell the European Union whether it will extend the delay, cancel Brexit or go through without a deal. "This is not enough time to agree, legislate for and ratify a deal, and yet the House has been clear it will not permit leaving without a deal".
With no majority in parliament for any Brexit plan so far, it is unclear what May will now do.
She now faces having to explain what happens next, after EU Council President Donald Tusk immediately called a Brussels summit for April 10. The EU has been preparing for this since December 2017 and is now fully prepared for a no-deal scenario at midnight on 12 April.
As a result of Friday's vote, the United Kingdom is now scheduled to leave the European Union on April 12, regardless of whether the two sides have reached an agreement to cushion the impact, which has led to concerns about crippling tariffs, border gridlock and shortages of food and medicines.
"We are not prepared to see our constitutional position altered by Brussels in a fit of pique for daring to leave the European Union", said MP Sammy Wilson, the DUP's Brexit spokesman.
May's spokesman said she would press on with talks with opponents of the deal.
28 March: British MPs can't reach deal, May offers to go, what next for Brexit?
The British military is preparing to deploy 50,000 soldiers on United Kingdom streets in the event of a "no deal" Brexit, anticipating a massive disruption of basic social functions, civil unrest and possible civil war.
Hilary Benn, a Labour Party lawmaker who chairs Parliament's Brexit committee, dismissed criticism that the parliamentary process was a failure because it didn't deliver a majority in the first round of voting.
Ms. May's political future is also in question. The Blairites fear that his election could fuel demands by workers and youth for him to make good on his rhetoric in opposition to austerity and war. Labour Party legislator Ian Murray likened it to the dead parrot in a Monty Python comedy sketch.
Tory Brexiteer Andrew Bridgen said leaving the European Union without a deal was the best option on the table. It is bereft of life.
The British Parliament will vote Monday on a variety of Brexit alternatives in an attempt to find an idea that can command a majority.
He said: "Whatever the deal looks like - and we understand there has to be compromises - if it's underpinned by a People's Vote that is the way we can bring the country back together".
Business groups, who have been sounding the alarm for months about the damage a no-deal Brexit could do, urged lawmakers to avert disaster. "No-deal is two weeks away".
The political morass has left Britons on both sides of the debate frustrated and angry.

One option afterwards is to pit the most-popular option against May's Brexit deal in a runoff vote, the BBC reported today.
"In view of the rejection of the Withdrawal Agreement by the House of Commons, I have chose to call a European Council on 10 April", said European Council President Donald Tusk, immediately responding to the result.
Friday's protest, a week after hundreds of thousands marched through calling for a second referendum, shows how divided Britain is over Europe three years after voting to leave the EU.
"One of the two routes to an orderly Brexit seems now to be closed".
"To do that, promise the British people that and then say "Actually, no, we need to just put it back" - absolute betrayal".
