The global antitrust team at Clifford Chance offers ‘a remarkably high standard of services’, advising on high complexity mergers and strategic behavioural cases in a range of sectors, including technology, life sciences, and consumer goods. Richard Blewett heads up the team, with longstanding experience internationally. Clients in the information technology sector often instruct Dieter Paemen, while work in the energy sector is a key area of strength for Milena Robotham. Anastasios Tomtsis provides both advice and representation before the European Commission and the CJEU for major corporations in State aid and foreign subsidies matters, and contentious antitrust matters are the focus for ’excellent adviser and advocate’ Ashwin Van Rooijen.
