JEREMY Corbyn is on course to change his position on Brexit and back staying in a form of the EU Customs Union.
The Labour leader is set to make a "seismic" speech on Monday where he is set to reveal that the party would give up the right to do independent trade deals when we quit the EU.
The news comes as Theresa May is facing a Brexit coup as Tory and Labour MPs joined forces to try and derail her divorce plans.
Today rebel Tories have launched an amendment to the upcoming trade bill to try and keep us in a form of Customs Union – and Labour Remainers reckon the rest of the party will back them in it.
Chuka Ummuna said this morning that it could shatter the Government's working majority of just 13. He said: "We believe this has the support to pass."
Sources told The Sun that the Liberal Democrats and the Greens would throw their weight behind it too. One insider said that up to 20 Tories would back the amendment.
Theresa May will make a major speech outlining her Brexit plans next Friday, it was confirmed today.
Last night Labour's Emily Thornberry revealed that the party would replicate the UK's current customs arrangement with the bloc.
And she confirmed that the UK would be unable to go it alone after Brexit.
The party have been under repeated pressure to soften their stance on Brexit to appeal to Remainers.
Previously Labour had echoed the PM, saying that Brexit means leaving the Single Market and Customs Union.
But Ms Thornberry told LBC Radio last night: “Technically, because we’re leaving the European Union, we can’t be in the Customs Union that we’re in now. So we leave and then we have to negotiate a new agreement.
“That we think is likely to be a customs union that will look pretty much like the current customs union.”
And John McDonnell said yesterday: "We are looking at a customs union."
MPs have said this week that Labour's position on the issue is "evolving".
Her bombshell comments immediately sparked cries of betrayal from Labour’s Brexit-backing MPs, who warned it could cost swathes of votes in the party’s northern heartlands.
What is the EU Customs Union and will we leave it after Brexit?
The countries sit down and decide to apply the same tariffs to goods from outside the union.
Theresa May has promised that Britain will leave the EU's Customs Union when we leave the bloc, which will mean we can sign our own trade agreements with other countries.
She is keen to draw up a bespoke trade deal with the EU, allowing for the free flow of goods and services while cracking down on European immigration.
Britain's membership of the Union currently stops us from negotiating free trade agreements with other countries.
Leaving would lead to mandatory customs checks for every lorry from Britain to the EU until a free trade deal is struck with Brussels.
Today Health Secretary Jeremy Hunt said there was no chance the Government would back membership of the Customs Union.
He told Radio 4's Today: "If we were part of the Customs Union we wouldn't be able to negotiate trade deals with other countries and wouldn't have full sovereignty of our laws."
And Brexiteer Jacob Rees Mogg said staying in such a union would mean continued higher prices on food and clothes.
"People who want a customs union want higher prices affecting the poorest on our society," he said.
Richard Tice, co-chair of Leave Means Leave, said today that Britain would thrive outside the EU.
He urged rebels to remember that less than a year ago both parties committed to leaving the Custom's Union.
"Betraying the manifesto less than a year after the election is completely unacceptable to those who voted for them," he added.
And MP Michael Fabricant insisted that backing the Customs Union would be a "total betrayal" of the Brexit vote.
Government sources said last night that key votes on this amendment have been delayed amid fears of the huge opposition.
The Prime Minister has repeatedly said we will leave the Customs Union after Brexit, but that there are other ways to ensure "friction-less" trade continues.
This is a total betrayal of what the 52% of the electorate voted for.
It will stop us controlling our own borders and prevent us from having an independent trade policy.
It will result in #Brexit in name, but not in reality. https://t.co/wPIJOvmAbZ
