The Competition Act 1998 made fundamental changes to United Kingdom competition law, introducing two new prohibitions based on European Community rules. In September 1998, the Centre for the Law of the European Union at University College London hosted a conference, chaired by Judge David Edward of the European Court of Justice, to discuss the Europeaniztion of United Kingdom competition law. This book brings together the papers delivered at the conference, together with additional papers exploring the effect of the Competition Act. The papers should be of interest to all practitioners, officials and academics working in the area of competition law.
