'Jonathan's Hopkin's work on the Spanish UCD is a fascinating description of the collapse of a political party which had successfully realised the transition from francoism and was the party of government for a number of years. Before the recent fall of some of the Italian parties, this case was almost unique in the western world: it remains a major puzzle which both academics and practitioners need to ponder. The end of the UCD is an example of failed or insufficient institutionalisation: there was too much of infighting among the 'chiefs'. Adolfo Suarez, the uncontested leader of the transition, was unable to bring these chiefs together. This works makes us reflect about the importance of leadership and the importance of party unity: these points do not concern Spain alone. There are lessons here for all western democracies, old or new.' - Professor Jean Blondel, Professor of Political Science, European University, Florence 'This book provides an impressive account of the collapse of the UCD, which is not only one of the most complex and ill understood events in contemporary Spanish history, but also a unique case in the recent evolution of Western European political parties. The book combines an original theoretical framework for the study of party organisation with a meticulous use of a wide range of empirical sources. The results of the research constitute an outstanding contribution both to the understanding of an exceptional case of party collapse, and to the development of theories of party organisation. As such, it is essential reading for students of Spanish politics and of party politics in general.' - Jose Ramon Montero, Instituto Juan March de Estudios e Investigaciones
