The European Factbook, now in its fifth 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  2012  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  16 out of 27 heads of state and government,  the  European  Commission with  13  Commissioners,  and  the  European Parliament  with 271 out of 754 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’.
