The Report on Competition Policy provides detailed information on the most important policy and legislative initiatives. The 2007 report describes: how the instruments of competition policy (antitrust, merger and State aid rules) were further developed and applied in general; how a mix of these and other instruments was used in selected priority economic sectors such as energy, financial services, telecommunications and IT; cooperation with national competition authorities and courts within the European Union, and with international organisations and external countries; cooperation with other EU institutions in the field of competition. This volume contains the report adopted by the Commission on 16 June 2008 and a more detailed Commission staff working document.
