Should the U.K. and Northern Ireland remain in the EU’s customs area after Brexit?

The UK and Northern Ireland are scheduled to leave the EU on March 29, 2019. Under a transition agreement all trade and economic relations between the UK and the EU will remain the same until the end of 2022. In 2018 members of parliament and Prime Minister Theresa May proposed a “backstop” which would allow the UK and Northern Ireland to remain inside the EU’s single market for goods and farm products. Proponents argue that keeping the UK in the EU’s customers area will boost the economy by streamlining trade and tourism. Opponents, including anti-EU lawmakers, argue that the backstop would lock the UK inside the EU’s customs area permanently and prevent it from signing trade deals on its own.
