Professional Biography

WWL Ranking: Thought Leader

WWL says

Mark Friend comes highly recommended by respondents who credit his profound knowledge of EU and UK competition law.


Mark Friend is head of Allen & Overy LLP's London antitrust practice and has been a partner since 1990, having qualified as a solicitor in 1982. He read law at Cambridge and obtained a master’s degree in EU law from the Université Libre de Bruxelles.

His practice encompasses all aspects of EU and UK competition law (including antitrust litigation), state aid and the economic regulation of utilities, with a particular focus on energy and water, and the regulation of payment systems. He has extensive experience of counselling and representing clients on complex mergers and strategic alliances, cartel, dominance and market investigations, at EU and national level, as well as advising public and private sector clients on more general issues of EU law.

Chambers and Partners notes: “Mark Friend is a highly regarded practitioner who receives strong praise from clients and peers. One source commented: ‘He is ferociously clever and has an ability to get to the heart of something in addition to excellent sector knowledge.’” He is also described as a “‘truly meticulous lawyer of great ability’ who provides ‘a balanced and nuanced understanding of issues’” by the competition section of The Legal 500 (2017).

He has published widely in academic and professional journals and co-authored the chapter on state guarantees in EU State Aids (edited by Hancher, Ottervanger and Slot, 2016). Mark is a member of the advisory board of the Competition Law Forum.

Allen & Overy's antitrust and competition practice comprises over 120 specialists operating across Asia, Australia, Europe and North America. The practice advises corporate clients and financial institutions on their global antitrust policies, litigation and regulatory strategies and has acted on some of the highest-profile and most complex cases in recent years.
