The scope and intensity of the challenges currently faced by western European political parties is exceptionally large, threatening the viability of the manner in which they have traditionally operated and causing them to seek new behaviours and strategies. This volume brings together some of the foremost scholars of European party politics, whose evaluation of political parties in 'the new Europe' is organised under four broad headings: Parties as Corporate Actors; Parties and Society; Parties and the State and Parties Beyond the Nation State. Each contributor not only provides a concise, critical review of the theoretical and methodological 'state of the art' in respect of a specific aspect, but also reviews the latest empirical findings in that area.
