Conservative lawmaker Phillip Lee resigned as a justice minister Tuesday so he could speak out against the policy on Brexit.
MPs voted to reverse the Lords amendment removing the exit day from the bill, meaning that 29 March 2019 is again the exit day after the government made "lots" of concessions according to a parliamentary.
The bill has also become of the focus of several attempts by MPs and peers to change parts of the government's approach to Brexit.
Dominic Grieve tabled an amendment last night which forced the government's hand over the issue of a meaningful vote.
The government won the vote after last-minute horse-trading, some of it in the open on the floor of the House of Commons - some behind closed doors.More news: Ford Mustang Shelby GT350 gets several upgrades
Passions ran high in Tuesday's three-hour debate, when angry eurosceptics accused their rivals of trying to undermine the 2016 referendum vote to leave the EU.
When the government realised it could be defeated solicitor general Robert Buckland confirmed to a packed chamber there was "much merit" in Grieve's amendment adding "the government is willing to engage positively".
307 Conservative MPs backed the government, which is a strong result for Theresa May, who just hours earlier had feared she would lose her majority due to disgruntled Tory MPs.
Her fellow Conservative backbencher Stephen Hammond said: "Parliament must be able to have its say in a "no deal" situation".
She told BBC Radio 4's World At One that "at least half a dozen" junior ministers had been "very uncomfortable for some time" at the Government's direction on Brexit. They told the anti-hard-Brexit rebels that they would propose their own amendment that, in effect, gave them what they wanted.More news: Morgan backs England to learn from shocking loss against Scotland
Just hours earlier, Downing Street had signalled the prime minister had no intention of accepting Grieve's compromise amendment to the European Union withdrawal bill, tabled by the former attorney general and aimed at ensuring ministers can't "crash out of the European Union by ministerial fiat", as he called it. The Daily Express thundered: "Ignore the will of the people at your peril".
'They want us to deliver on Brexit and build a brighter future for Britain as we take back control of our money, our laws and our borders'.
Another flashpoint could come when lawmakers vote Wednesday on an amendment seeking to keep Britain in a customs union with the EU.
Dismissing claims that Mrs May had effectively abandoned her threat that the United Kingdom could leave the European Union without a deal, Mr Jenkin said: "There is only agreement for discussions, not concessions".
'The objective of the EU Withdrawal Bill is simple - it is putting EU legislation into law to ensure a smooth and orderly transition as we leave, ' she is expected to tell them.More news: Justify's value skyrockets to $60M with Triple Crown win
