Since its inception the European Union has been a fiercely contested and politically divisive project. In recent years, controversial issues such as EU enlargement, the ratification of the Lisbon Treaty, and the fallout from the Eurozone crisis have tested the EU to its limits and divided public opinion in the process. This innovative volume brings together leading scholars from around the world to debate the nature, current state and future of European integration. The contributors represent the whole spectrum of thinking about the European Union, ranging from pro-European to openly Eurosceptic perspectives. Within the book, chapters present two opposing perspectives on a wide range of controversies. Among the issues discussed are: how efficient is the European Union? Has the European project been a success? Will the Eurozone survive in its present state? And can the EU tame big finance? Guaranteed to illuminate as well as spark debate, this text provides an engaging and incisive overview of the most important issues in contemporary EU politics.
