A&O Shearman’s ‘brilliant’ competition law team possesses the skills and knowledge necessary to handle a wide range of prominent competition and antitrust matters across various industries. Renowned in the financial services sector, the firm is highly sought after by major UK and international banks for advice on mergers and cartel investigations.

Assisting Mansfield is an impressive group of partners, including Dominic Long, who splits his time between the London and Brussels offices and specialises in complex cross-border merger clearances and cartel investigations, with a particular emphasis on the TMT, energy, and healthcare sectors. Seasoned EU antitrust practitioner Kristina Nordlander has specific expertise in the tech and life sciences sectors. Thomas Masterman has acted on some of the most high profile M&A matters, and a recent highlight includes advising Recticel on the CMA Phase II review.
