EU Chief Negotiator, Michel Barnier, has said that the Withdrawal Agreement is not going to be reopened. 

It comes ahead of crunch talks between the EU 27 and Theresa May as she heads for top-level Brexit talks in Berlin and Paris seeking support for another extension.

All 27 remaining EU heads of government must agree to an extension if the UK is to avoid the default position of a no-deal Brexit on Friday night.

Reports suggest that Brexit could be delayed for up to a year if an extension is agreed, however, it would appear that the EU will not be open to a renegotiation of terms. 

Speaking ahead of the emergency EU Council tomorrow, Michel Barnier said: "An orderly withdrawal of the United Kingdom - This is something that has, on a daily basis, been our objective, and it remains our objective.

"Obviously, an orderly withdrawal implies the best possible conditions for the second set of negotiations, equally important in my mind, the negotiations for the future partnership with the UK that will and would remain a friend, partner and ally. 

"A new element in this very serious and complex context we are operating within is, of course, the fact that we have had cross-party discussions initiated finally with Labour by Theresa May.

"We all expressed our hopes and expectations with regards to these cross-party negotiations, our expectations and our hope that this dialogue will conclude with a positive result, which will allow us at last to have a positive majority in regards to this Withdrawal Agreement."

He added: "You will have heard me say on a number of occasions - first of all, that the Withdrawal Agreement is not going to be reopened, is not up for negotiation again, and that continues to be the case.

“The Political Declaration, which will set the framework for future relations, can be improved, we can provide an increased level of ambition if that is the wish of the UK.

“These ambitions for the future relationship, which could – for example – consist of adding to the free trade agreement on which we have agreed with the UK already a customs union, a genuine customs union.

“We are willing to improve and amend the Political Declaration rapidly, within a few hours or days.”
