After a disastrous vote in the House of Commons on her withdrawal agreement with the European Union, Theresa May presented her alternative Brexit plan to the members of Parliament on January 21.

May said that after hearing the concerns of Parliament, she is seeking to gain concessions from the EU on the controversial Northern Ireland “backstop,” or temporarily fluid border between EU-member Ireland and Northern Ireland, which is part of the United Kingdom. The backstop remains the most contentious issue of Brexit negotiations and faces opposition on all sides of Parliament.
