In recent years there has been a considerable effort in some transnational organizations and institutions to confront a crisis of legitimacy by promising more accountability and openness. This volume takes as its central focus the role of accountability in democratic governance, and attempts to position a broad understanding of the notion of accountability within the overall context of the evolving political system of governance in Europe and in particular of the European Union. Bringing together new work by some of the leading scholars in the field, this volume considers the relationship between accountability and a wide range of other themes in European governance such as problems of representation, transparency, bureaucracy, and transnational relations. The volume also deals with the role of accountability in multi-level governance, and its relationship to both direct democracy and civil society.This book was published as a special issue of West European Politics.
