Current forecasts suggest she will lose the vote.
Below is a running tally of the number of lawmakers who have so far explicitly indicated during the debate whether they plan vote for and against the Brexit deal on December11. "She absolutely believes it's the right deal for the country".
But the scale of the threatened defeat has left some speculating whether May could postpone the vote.
Asked if there was any sense that there were just five days to save the Prime Minister's premiership, he replied: "No".
May used an interview on BBC radio on Thursday to press on with her bid to persuade lawmakers to back her deal.
In one small potential change, May said she was speaking to lawmakers about giving parliament a bigger role in deciding whether to trigger a so-called Northern Irish backstop. "The legally binding global Withdrawal Treaty would remain fundamentally flawed as evidenced by the Attorney General's legal advice".
"And that's why it's important that ministers are out speaking with communities across the United Kingdom today about how the deal works for them".
"He added: "[However] it is better to have momentum around the deal that is on the table, rather than returning to the drawing board - unless a credible "Plan B" is truly deliverable before the end of next March".
Minutes later, European Union chief negotiator Michel Barnier declared there had been "decisive progress" - the key phrase signaling European Union leaders can convene a summit to approve the deal, probably later his month.

"They resemble the kind of diktat that might be imposed on a nation that has suffered a military defeat", he declared.
Amid fears that British ports may face gridlock should a divorce deal not be agreed, Hancock said that trucks carrying drugs would be fast-tracked.
"The Government recognises the vital importance of medicines and medical products and is working to ensure that there is sufficient roll-on, roll-off freight capacity to enable these vital products to continue to move freely in to the UK", Hancock said.
Concerns that Britain will leave the European Union in March 2019 without a deal have already hammered the pound and could cause dislocation in global markets, regulators and business leaders have warned.
Meanwhile, Foreign Secretary Jeremy Hunt warned of "real social instability" if a second referendum resulted in a victory for Remain. "It is a vote in which the future of their country is at stake".
If a fresh poll reversed the 52%-48% majority for Leave in 2016, Leave supporters "would be incredibly angry and I wouldn't rule out real social instability in this country", he said. We could have a similar situation, the only blessing they've got is that the Labour Party is nowhere almost united under Jeremy Corbyn as it was under Tony Blair.
That would mean Mr Corbyn becoming prime minister as he tries to build a coalition of support in the parliament. But this is 2018 and if the defeat is heavy enough it can not be totally ruled out. "Those should include Labour's alternative and, as our conference decided in September, the option of campaigning for a public vote to break the deadlock".
Downing Street said there was not a full Cabinet meeting and "nothing to get excited about".
