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."

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.

This book examines the relationship between flexible regional economic integration in the East African Community (EAC), through its application of variable geometry, and the establishment of the African Continental Free Trade Area (AfCFTA) as a continent-wide form of integration. It uses a historical, political, legal and economic analysis of the processes that led to the adoption of flexible regional integration in Africa, with particular regard to the EAC. This takes place in the inescapable context of pan-Africanism, showing how regional integration efforts in Africa are based on pan-Africanist ideals, and how an evolution of these ideals has led to an evolution in the goals of integration. With growing awareness of the weaknesses and impracticality of consensus-based decision-making on a global level, it makes the case for the pursuit of flexibility in multilateral trade, drawing lessons from the experience of the AfCFTA and blocs in other regions. This book is a historical evaluation of regional economic integration efforts in Africa and it follows the path of attempts to integrate the economies on the continent from colonial times to the birth of the AfCFTA. While it is a study in law, it relies heavily on politics, economics and history to weave together a more complete theory of economic integration based on the African experience. Flexible Regional Economic Integration in Africa was awarded the 2020 SIEL–Hart Prize in International Economic Law.

The European Union (EU) is often portrayed as sacrificing national diversity for European unity. This book explores the alternative of a flexible EU based on differentiated rather than uniform integration. The authors combine normative theory with empirical research on political party actors to assess the desirability and political acceptability of differentiated integration as a means of accommodating heterogeneity in the EU. They examine the circumstances and institutional design needed for flexibility to promote rather than undermine fairness and democracy within and between member states. Clear, balanced, and accessible, the book provides fresh thinking on the future of the EU.
