The European Factbook is the consolidated annual publication with all relevant data and documentation about the European People’s Party (EPP), the largest European level Party that represents the centre-right political spectrum. The 2010 edition includes the latest updates and information from both European level and national level politics. With the Lisbon Treaty now in force, 2010 finds the EPP as the leading Europarty in the three main EU institutions: the European Commission, the European Council, and the European Parliament. Apart from the structure of the EPP and its role in the EU institutions, the European Factbook includes information about EPP member-parties in EU and non-EU countries, EPP parliamentary groups in the Council of Europe and the OSCE, EPP member-associations, as well as information about EPP’s think-tank the Centre for European Studies (CES) and its member-foundations. Finally, the European Factbook provides readers with a set of important supplementary documents.
