What are the EU’s requirements?
The EU has already demanded, and won, a pledge that Britain will pay the $51 billion it owes in EU officials’ pension costs and other obligations. It is adamant that Britain cannot have unfettered access to the vast EU single market unless it adheres to all of the EU’s “four freedoms”—free movement of goods, services, capital, and people. The EU says it can’t allow Britain to choose just one or two of those four commitments, lest Brexit set a precedent for other restless countries that might wish to strike their own bespoke bargains. Most importantly, the EU has taken the side of its member state Ireland in insisting that the border between the Irish Republic and the U.K. province of Northern Ireland remain open and free for travel and trade after Brexit.
