The timing gives Mrs May a fortnight to avert what threatens to be a humiliating defeat at the hands of scores of Conservative rebels.
Thirteen British citizens residing in European Union countries asked the General Court in Luxembourg to annul the decision of European Union governments authorizing the opening of negotiations on Brexit.
"This is the deal, it's the best deal possible and the European Union will not change its fundamental position when it comes to this issue, so I do think the British parliament - because this is a wise parliament - will ratify this deal", he added.
"Hopefully, she'll be able to do something about that", he said, referring to May.
Ex-defence secretary Sir Michael Fallon described the deal as "a huge gamble" which involved the United Kingdom paying a £39 billion divorce bill and giving up its votes and veto without any firm commitment on future trade relations.
And he said "I am not a fortune teller" in regards to what would happen if the British Parliament doesn't approve the agreement.
There will be common customs arrangements to provide tariff-free trade, and the two sides commit to "build and improve on" the temporary single customs territory set out in the withdrawal agreement.
"This is that deal. A deal that delivers for the British people".
Mrs May's spokesman declined to confirm or deny reports that Number 10 is considering a possible TV debate with Labour leader Jeremy Corbyn. The Labour Party, the Democratic Unionist Party of Northern Ireland and some hard-line Brexit supporters in Mrs May's Conservative Party have vowed to vote against the deal.
The U.K.is due to leave the European Union at midnight Brussels time on March 29.
Britain's economic growth has slowed since the 2016 Brexit vote, largely in line NIESR's pre-referendum projections of the impact of a "Leave" vote, but not by as much as many forecasters predicted.
May will now embark on an intensive nationwide campaign to promote the deal with voters across the country and lawmakers in London.
She told the Sun: "I looked at the remarks that President Macron made".
"I think we managed to make a diplomatic piece of art", she said.
Mrs May's official spokesman told reporters: "The Prime Minister's colleagues today congratulated her and thanked her for all her hard work in securing this deal".
But the Prime Minister insisted fishing rights were a major win for her in the 20 month-long Brexit divorce deal negotiation.
"The only way to resolve this looming crisis is for MPs to hand such a crucial decision back to the British people by giving them the final say on Brexit through a People's Vote".
A no-deal Brexit would "cause huge disruption at the borders, it would mean tariffs and checks at the borders, and all sorts of unforeseen circumstances, and so that's something that a lot of lawmakers are very keen to avoid", Javed said.
The prime minister has shown little sign of changing tack to try to curry favour, but will deploy some of the weapons in her armoury to try to persuade lawmakers. She faces tremendous opposition.
