May risks Brexit row over migration, trade during transition

Theresa May will address Parliament around 3.30pm UK time on Monday, saying that after March 2019 she wants Britain to leave the EU’s single market and customs union while retaining most of the benefits of membership. While the EU has said this will mean abiding by its rules, the prime minister will propose a diverging course in at least two areas.

"During this period we intend to register new arrivals from the EU as preparation for our future immigration system," May will say, according to her office. "And we will prepare for our future independent trade policy by negotiating -- and where possible signing -- trade deals with third countries, which could come into force after the conclusion of the implementation period."
