Clear, balanced and accessible, this book explores the alternative of a flexible European Union (EU) based on differentiated rather than uniform integration. They examine the circumstances and institutional design needed for flexibility to promote rather than undermine fairness and democracy within and between member states.

Flexible Integration is a model of reform designed to overcome the current stalemate between federalists and anti-federalists. It introduces more flexibility to accommodate the heterogeneous interests in Europe without risking the gains achieved through past integration. Flexible integration combines firm commitment by all members to a supranational common baseincluding a well-defined set of competences related to the Single Market - with optional integration in other areas through open partnerships.

Alexander Stubb, a participant in the 1996-97 and 2000 Intergovernmental Conferences analyzes the evolution of flexible integration from the early 1970s to the present day and beyond. He focuses in the process of negotiations which led to the institutionalisation of flexibility in the Amsterdam and Nice Treaties. This book provides a valuable insider's view on historical decisionmaking in the European Union.

In Europe, the period of great economic and demographic growth is largely over. The physical growth of our urban agglomerations has come to an end. Unlike in Latin America, Asia or Africa, the boundaries of European cities are no longer moving away, but have come to a halt. The spatial assignment of the future European city will be fundamentally different. Building new space outside the city boundaries is no longer necessary. Instead, what exists should be made sustainable. The new spatial assignment involves maintaining, restructuring, densifying or diluting the existing city. This publication analyses this development and describes a toolbox that is able to turn the new assignment into a success. European cities are compared, similarities and trends are identifi ed and concrete examples are described in detail. This creates an inspiring handbook for anyone working on the future of the European city: from administrators and policymakers to developers, designers, builders and users.

Based on a theory of differentiated integration, this book investigates the dynamics of flexible European integration across EU policies and member states. By doing so, it provides a theory-based, comprehensive, and an empirical account of European integration from the perspective of legal differentiation.

In the last decade, the EU has been hit by a series of crises, most recently the UK's decision to leave the union following the Brexit referendum. In light of this, questions have been raised about the need to reform the whole model of European integration, with the aim of making the union more flexible and more accountable. In this book, Richard Youngs proposes an alternative vision of European co-operation and shows how the EU must re-invent itself if it is to survive. He argues that citizens should play a greater role in European decision-making, that there should be radically more flexibility in the process of integration and that Europe needs to take a new, more coherent, approach to questions of defence and security. In proposing this model for a `reset' version of Europe, Youngs reinvigorates the debate around the future of Europe and puts forward a new agenda for the future of the EU.

Flexibility is emerging as a key dynamic of European integration. This shift towards flexibility has major implications. The EU will have to cope with more complexity and less transparency. It also affects the way in which European integration is viewed since it makes a state-like outcome to the process far less likely. Alex Warleigh looks at why flexibility has become such an important feature of the EU. He examines its history, and puts forward a typology to explain the models by which it is understood. He goes on to explore the hazards of flexibility and to look at what it has to offer, arguing that it is best seen as a desirable part of the integration process rather than as a problem. Flexibility, he argues is an important mechanism for the realization of the EU's slogan "unity in diversity."
