She passionately represents clients in the management of internal and external investigations, including developing robust compliance programs, responding effectively to dawn raids and requests for information from UK and EU antitrust authorities, conducting in-depth forensic investigations, audits and witness interviews, securing favourable settlements with government agencies and developing defence strategies in competition damages litigation.

Mara has also spent time working in Baker McKenzie’s Brussels and Tokyo offices working closely with multinational companies to design business strategies in compliance with EU and UK competition laws.
