The European Factbook, now in its fourth year, is the consolidated annual publication with all relevant data and documentation about the European People’s Party (EPP), the largest EU-level Party which represents the political family of the centre-right. The 2011 edition includes the latest updates and information from both European level and national level politics. With the Lisbon Treaty now in force, the EPP is currently the leading Europarty in the three main EU institutions: the European Council with 17 Prime Ministers, the European Commission with 13 Commissioners, and the European Parliament with 264 MEPs. 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, the OSCE and NATO, 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 including the 'Giannakou Report', which was adopted earlier this year by the European Parliament.
