Le Monde: Irish question complicates Brexit deal between London and Brussels
Summary: Theresa May meets on Monday the presidents of the European Commission, Jean-Claude Juncker, and the European Council, Donald Tusk.
Six months after the start of the Brexit negotiations, London and Brussels are getting closer to an agreement to finally move on to discussions about their “future relationship”.
In order to finalize the terms of this agreement, British Prime Minister Theresa May was scheduled to meet with Donald Tusk, the President of the Council (the Member States), and Jean-Claude Juncker, the President of the Commission, in Brussels on Monday 4 December.
The formal passage to the discussion on “future relations” is conditional on the recognition by the Europeans that “sufficient progress” has been made regarding the divorce itself.
The twenty-seven have forced the British to focus on three Brexit “priorities”: the fate of European expatriates settled in the UK after the exit of the European Union (EU), the “bill” of the Brexit (the commitments that London still has to honor after the divorce).
And the fate of Ireland, that the announced exit of the United Kingdom from the single market and the customs union, should affect more than all the other members of the Union.
