Another crucial day for Brexit: in the midst of optimism, new obstacles have emerged

In this last straight line, optimism and prudence go hand in hand. "An agreement is possible, but many problems still need to be solved."said the Irish Prime Minister of Dublin: Leo Varadkar.

London and Brussels have decided Friday to give a new impetus to the negotiations to try to reach an agreement before the meeting of the president scheduled Thursday and Friday, to avoid negotiating at the summit.

If the British Prime Minister, Boris Johnson, does not reach an agreement for Saturday, a law of his Parliament requires him to request a further extension of the date of divorce, the third since March, for which he is reluctant.

The British Minister of Brexit, Steve Barclay, confirmed to the British deputies the will to comply with the law, but reaffirmed his commitment from the end of November so that they have "intense negotiations".

Negotiators are trying to see how to ensure a fluid trade in goods between Ireland, an EU country and the British province of Northern Ireland, territories that already enjoy the free movement of citizens between them.

The aim is also to protect the 1998 Good Friday Peace Accords, which ended decades of bloody conflict on the island of Ireland, and to protect the single European market from its partner's "landfills". always in place.

"The negotiations have begun to translate the British proposals into a legal text, but there are difficulties on the merits"said a diplomat, adding that maintaining a level playing field was a sore point.

The basis of the discussions is the Johnson Government's proposal, inherited from its predecessor. Theresa May a divorce agreement that his Parliament rejected, among other points on the Irish question.

Johnson abandoned the idea of ​​keeping the whole of the UK in a customs union with the EU while finding a better solution in the negotiations of a free trade agreement. but the new plan raised doubts.

The British "Prime Minister has modified his original proposal so that there is no customs border" on the island of Ireland, said a European source, referring to the One of the "hotspots" of the Europeans.

Another problem is the right of veto that, according to London, would have the North Irish Parliament, which could decide every four years if it wishes to continue to abide by the rules of the European Single Market in Northern Ireland.

The leader of the Norwegian trade union party DUP, Arlene FosterJohnson's support for Westminster, told the BBC that he wanted to support an agreement, but that he would not do it if he felt it would separate Ireland from the North of the rest of the United Kingdom.

His words allow you to plan the uncertainty of whether the British Parliament could approve a possible agreement between London and Brussels, before the pronouncement of the Eurocamara, the necessary procedures for an orderly exit.
