With just two days to go before the Commons vote on her Withdrawal Agreement, the Prime Minister pleaded with parliamentarians to "do what is right for our country" and back her deal.
The Times reports that Tory Whips are using the the plot as a means to pressure Brexiteers into support Mrs May's Withdrawal Agreement on Tuesday, which would leave the United Kingdom in a position of paying a £39bn divorce bill, remaining in a "transition period" for almost two years, and could endanger the Union by locking Northern Ireland into regulatory alignment with the bloc if a deal is not struck.
'Doing so would be a catastrophic and unforgivable breach of trust in our democracy.
Britain, the world's fifth largest economy, is scheduled to quit the European Union on March 29.
Meanwhile, Work and Pensions Secretary Amber Rudd said she was "committed" to ensuring that the United Kingdom did not leave without a deal. May postponed a vote on the agreement in December to avoid a resounding defeat, and there are few signs that the deal has picked up support since then.

James Kuffel, the township's lone constable, said he knows nearly everyone in the area but has never encountered the Pattersons. While authorities are still trying to determine the motive behind the kidnapping, more details about Patterson have emerged.
The Sunday Times says that the plan by backbenchers would see the government lose control of parliamentary business.
Work and Pensions Secretary Amber Rudd also highlighted Cabinet divisions and suggested it was wrong to criticise Commons Speaker John Bercow over his controversial decision to allow MPs a vote on an amendment to the timetable of the Brexit deal.
Meanwhile, James Starkie, a former Vote Leave campaigner and ex-adviser to Environment Secretary Michael Gove, has told the BBC that a no-deal Brexit could have an impact on food imports from Europe. Every single household - rich or poor - would be worse off for many years to come.
He added that a "new process" of national consultation was needed, adding: 'No true democracy should deny a considered choice to its people'.
The Labour leader insisted his Brexit plan, condemned by some critics as unrealistic as it would contravene basic European Union internal rules, was viable.
'We'd be in a stronger position, then, to continue the negotiations as an independent third country'.
