Mark Simpson is a partner at Norton Rose Fulbright LLP in the antitrust and competition practice group in London. He advises on all aspects of UK and EU competition law, with a particular focus on investigations and competition litigation, including regulatory appeals and judicial review. Mark advises corporates, trade associations, government agencies and regulators, and his perspective in doing so is informed by having spent periods in in-house roles, most recently as a senior competition counsel at a telecommunications company.

Mark has experience in competition cases before the English High Court (Commercial Court and Chancery), in the Competition Appeal Tribunal and before the CMA (and its predecessor, the Competition Commission) and the European Commission. He has been involved in a range of follow-on damages cases over the last 10 years, representing both defendants and claimants, and is currently advising on a number of ongoing proceedings issued in the English courts.
