'This stimulating study looks behind and beyond many of the conventional accounts of key negotiations within the EU on issues of treaty reforms. Its insights contribute to a deeper understanding of the complex bargains through which crucial decisions are taken on controversial issues.' - Helen Wallace, Director, Robert Schuman Centre for Advanced Study, European University Institute 'Looking beyond the controversy between intergovernmentalists and supranationalists, Derek Beach's well-written new book makes an important contribution to the study of European integration. The theoretical approach provides an interesting perspective on the leadership potential of the EU institutions and his in-depth comparative analysis of the negotiation of every major IGC since 1985 provides new, interesting and sometimes even surprising insights into their respective influence but also in relation to the democratic deficit in the EU.' - Wolfgang Wessels, Jean Monnet Professor of Politics and European Studies, University of Cologne, Germany '[S]ystematic in its treatment and original in its findings...an innovative study...based on extensive archival work and interviews...The book's great strength is to elucidate leadership opportunities offered to supranational institutions through their capacity to minimise transaction and bargaining costs.' - Alistair Cole, The Times Higher Education Supplement '...brings important new insights into the complexities of the functioning of the EU'. - Marek Rybar, Political Studies Review
