"This timely book explores EU impacts during the first four years of membership in the leading accession countries and traces their significance in a series of well-researched country studies. A further chapter explores the impact of EU entry on issue stances and programmatic coherence on a comparative basis. This is essential reading for those interested in the growing field of Europeanisation studies and the problematic development of party politics in Central and Eastern Europe." Professor Paul G Lewis, Open University, UK"This is a nuanced and sophisticated account of the impact of the European Union on post-communist, democratic, party politics. Both the comparative analyses and the in-depth country chapters show where, how, and why the EU influences domestic party politics—and why it so often does not, even in new member countries. This innovative volume undermines the common assumption that the EU is a powerful player in domestic politics and, as such, is a must read for scholars and policymakers alike." - Professor Anna Grzymala-Busse, University of Michigan, USA"Tim Haughton’s book is an important contribution to the literature on the Europeanisation of national political parties. It not only describes in detail the characteristics of the EU’s impact on political parties in the countries in question shortly before and right after their accession to the EU, but it is itself an extended source of information that undoubtedly can better the understanding of these countries’ current political situations. These two aspects make the volume very helpful for academic researchers, students and practitioners." - Dragomir Stoyanov, Sofia University - Europe-Asia Studies (2013)
