The EU during Brexit

Abstract

This chapter analyses the European Union during Brexit, explaining how the EU institutions and Member States reacted to the UK’s decision to leave the EU. It outlines how they went about this in the course of the withdrawal negotiations. The EU institutions and Member States managed to adopt a very united stance vis-à-vis a withdrawing state, establishing effective institutional mechanisms and succeeding in imposing their strategic preferences in the negotiations with the UK. Nevertheless, the EU was also absorbed during Brexit by internal preparations to face both the scenario of a ‘hard Brexit’—the UK leaving the EU with no deal—and of a ‘no Brexit’—with the UK subsequently delaying exit and extending its EU membership. Finally, during Brexit the EU increasingly started working as a union of 27 Member States—the EU27—which in this format opened a debate on the future of Europe and developed new policy initiatives, especially in the field of defence and military cooperation.
