The European Union (EU) is in crisis. The crisis extends beyond Brexit, the fluctuating fortunes of the eurozone and the challenge of mass migration. It cuts to the core of the EU itself. Trust is eroding; power is shifting; politics are toxic; disillusionment is widespread; and solidarity has frayed. In this major new text leading academics come together to unpack all dimensions of the EU in crisis, and to analyse its implications for the EU, its member states and the ongoing study of European integration. This remarkably well-written edited volume fills a gap in the literature by providing a solid account of the EU integration crisis. It is an essential guide especially for political science, international relations and economics students, as well as EU scholars and practitioners at EU and national levels to better understand and analyze the EU integration crisis case by case and in toto from different perspectives.
