THERESA May has refused to back down on her hated Brexit deal, despite Tuesday night’s humiliating defeat.

Immediately after her agreement with the EU was rejected in the Commons by 432 votes to 202, the Prime Minister promised to hold “constructive” cross party meetings to identify a Brexit plan that would win the support of MPs.

But yesterday there was little sign that she was willing to shift too far from the deal that had been so roundly opposed.

“If none of PM’s red lines change, what progress can she possibly make?” Nicola Sturgeon wrote on Twitter.

To get Labour on board, May would need to agree to a softer-Brexit, keeping the UK in a customs union with EU.

To get support from the DUP and the ERG, she would need to scrap the backstop in the Withdrawal Agreement, but the EU have insisted that will not and cannot change.

Another option being floated by a number of Tory and Labour MPs, and previously the Scottish Government, is the so-called Norway plus model.

This would scrap the need for the backstop, and see the UK being part of the European Economic Area by becoming a member of the European Free Trade Association.

But it would force May to give up one of her most fundamental red lines, ending free movement of people.

During an interview with the BBC, Justice Secretary David Gauke had suggested the Government could be “flexible” on discussions around a customs union.

But speaking to reporters afterwards, May’s official spokesperson said this was not the case: “The principles that govern us as we go into these talks is that we want to, among other things, be able to do our own trade deals and that is incompatible with membership of either a or the customs union.”

The SNP’s Stewart McDonald was one of many MPs to push May on the issue in parliament “The deal defeated last night is a product of the Prime Minister’s own red lines.

“Which of those red lines is she willing to give up in order to get the compromise she seeks?”

May insisted she would be “approaching these discussions in a constructive spirit”, but said there was a need for the government to “deliver on the referendum result and deliver Brexit.”

Labour MP Yvette Cooper said the Prime Minister was acting as if her deal had been “defeated by 30 and not 230” votes.

May replied: “What I want to see is what the British people voted for. They voted for an end to free movement, they voted for an independent trade policy, they voted to end the jurisdiction of the European court of justice. And it is incumbent on this parliament to ensure that we deliver on that.”

Jeremy Corbyn said May was in “denial” about “the scale of the defeat” her deal had suffered.

The Tory’s leader unwillingness to shift fuelled speculation she was going to bring her rejected deal back.

One cabinet minister said Evening Standard that there could be at least “one or two more votes” on the withdrawal agreement.
