Mark D. Powell


Mark has been advising clients on competition law issues for nearly thirty years. His practice has a particular focus on the interface between competition law and sector-specific regulatory requirements, in such areas as telecommunications, pharmaceuticals, energy, the media and transport. Clients benefit from his considerable experience handling regulatory clearance for complex mergers and acquisitions, including Zimmer/Biomet, Telia/Telenor (abandoned), Acergy/Subsea7, HBO/Ziggo, and Sanofi-Aventis/Zentiva. His work on Aegean/Olympic II was so persuasive that it resulted in the European Commission clearing it in a Phase II proceeding- the first time that it had cleared such a deal, having previously prohibited it. In addition, Mark has developed a significant track record representing and advising clients involved in cartel investigations, in areas including Euribor derivatives, nucleotides, synthetic rubber, candle wax, calcium carbide, ball bearings and power cables. He has helped clients to make successful appeals to the European Commission regarding matters ranging from infringement decisions to the re-negotiation of fines. Based in Brussels and London, he is able to advise international clients on both European and UK market investigation and merger cases. Mark was singled out for recognition in the first edition of Euromoney’s Expert Guide to the World’s Leading Competition and Antitrust Lawyers. He has been described by clients in The Legal 500 EMEA as "very knowledgeable with a pragmatic and commercial approach… [and] a convincing style and self-confidence which… is very persuasive." Chambers has noted that clients value Mark as "a charismatic lawyer with terrific business sense" who is "practical and savvy" and "enjoyable, hard-working and client-friendly".
