DUBLIN/BRUSSELS—Britain agreed on Monday Dec. 4. to keep Northern Ireland in “regulatory alignment” with the European Union after Brexit, Irish government sources said, raising hopes Prime Minister Theresa May can strike a deal in Brussels to start free trade talks.
After intensive negotiations in recent days, Britain made what the Irish sources called a clear commitment to keep economic rules on both sides of the new UK-EU land border across the island of Ireland similar enough to allow no frontier.
