The volume addresses a basic issue: have parties in Southern Europe weakened over the decade 1995-2005? Or have they rather changed? And if so, how have they changed? To answer these questions the authors analyse the transformations undergone by the two main parties in Italy, Spain, Greece, Portugal and Cyprus (North and South) focusing on several dimensions of change. For each party systematic analysis is offered on party organization; electoral politics; competitive strategies; party values and programmes.
