That is according to the international trade secretary Liam Fox who told the Sunday Times that "if we do not vote" for the existing withdrawal agreement then chances of exiting the European Union would be around "50-50," down from a 100% certainty should May's Brexit deal pass.
"What you can be sure of is that if we vote for the prime ministers deal then its 100% certain that we will leave on March 29," Fox said.
"If we do not vote for that, Im not sure I would give it much more than 50-50. And for me that would induce a sense that we had betrayed the people that voted in the referendum."
Failure to support the Brexit deal "would induce a sense that we had betrayed the people that had voted in the referendum," Fox said.
"As far as Im concerned, as an elected member of parliament, Ive been given an instruction by the British people and its my democratic duty to do it.
"Weve been given a clear instruction. Its time parliamentarians put their own pride behind them and started to act with the spirit of humility and delivering to the people what they were promised."
Liberal Democrat MP Layla Moran, a leading supporter of the Best for Britain campaign for a referendum, said Fox's 50-50 calculations are slightly off. "Brexit not happening isnt 50-50 as Liam Fox says," she said, according to ITV .
"Its actually 56-44. Thats the way the public now feels about us stopping this badly-led disaster and strengthening ourselves within the EU.
"The only thing that is shattering the bond of trust between electorate and Parliament is the refusal of ministers like Liam Fox to trust people with the final say on Brexit."
