European integration is progressing at an even more rapid rate. Accompanying this progress is an increasing debate about the institutional shape and legitimacy of this new political order. This debate is driven in part by conflicting values, and in part by uncertainty. This book addresses the question of parliamentary involvement in the emerging European political system by looking at both national and European levels of parliamentary representation. In doing this, it gives greater attention to the role of national parliaments than is usual in discussions about democracy in the European Union. Based on interviews and surveys among members of parliament at the European level, and in eleven member states, it analyses the role of parliaments and parliamentarians, the linkages between national citizenry and the European level, and the problems and perspectives of institutional change. The book is provides analyses of the views from within concerning European integration and concentrates of three dimensions: the MPs themselves; their embeddedness in the process; and their perspectives on institutional structures. These views from within offer new insights and answers to institutional problems in the European Union and the so-called democratic deficit.
