This state-of-the-art study traces the relationship between Europeanization and multi-level governance, two key concepts that have become increasingly important in recent years. Through the lens of cohesion policy, Ian Bache illustrates how the EU has affected the vertical and horizontal dimensions of domestic policymaking. The author focuses especially on Britain, comparing its experiences to that of ten other member states. Bringing together the conceptual tools of multi-level governance and policy networks and developing a framework for using these tools together in future research, this concise and clearly written study will be valuable for scholars and students of EU and British politics.
