BREXIT has a 50 per cent chance of being scrapped if Theresa May’s deal is rejected by MPs, Liam Fox has said.

Dr Fox, a pro-Leave minister, said Brexit will only be “100 per cent certain” if the House of Commons backs Mrs May’s deal in a crunch vote next month.

He told the Sunday Times it would be “incendiary” if fellow MPs fail to pass the Prime Minister’s Withdrawal Agreement.

The International Trade Secretary, 57, added it was a “matter of honour” for them to support her.

Referring to the EU referendum, he said: “Parliament cannot now, with any honour, renege on that result.”

He added: “Were they to do so, I think you would shatter the bond of trust between the electorate and Parliament.

“And I think that would put us into unprecedented territory with unknowable consequences.”

Dr Fox said he “would not give it much more than 50-50” for the UK to leave the EU if Mrs May’s deal is rejected.

Campaigners for a second EU referendum seized on the International Trade Secretary's comments, saying that polls suggested that fewer than 50 per cent of Brits now want to leave the EU.

Liberal Democrat MP Layla Moran, a leading supporter of the Best for Britain campaign for a referendum, said: "Brexit not happening isn't 50-50 as Liam Fox says. It's actually 56-44.

"That's 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."
