John Gibson advises multinational organizations on complex investigations, economic crime, and regulatory enforcement, with particular focus on cross-border matters involving financial misconduct and reputational risk. He defends high-profile individuals and corporations charged with serious economic crime and related offences. In addition, he has a client base of family offices, sovereign states, and high-net-worth and politically exposed individuals. His matters routinely begin as front-page financial news, requiring a deft and comprehensive strategy to limit reputational harm, demonstrate a robust response, and shape the narrative.

With a practice rooted in international financial crime, John is highly trusted and respected by corporate  boards  and senior executives navigating bribery, corruption, fraud, and sanctions concerns, often in parallel investigations by agencies such as the Serious Fraud Office (SFO), Financial Conduct Authority (FCA), Department of Justice (DOJ), and Securities and Exchange Commission (SEC). His matters frequently span multiple jurisdictions.

For four years, John was a senior prosecutor at the UK’s Serious Fraud Office, playing a central role in several high-profile bribery and corruption investigations and successful prosecutions involving global businesses and inter-governmental cooperation. Prior to this, he was a member of the Independent Bar in London, appearing in a wide range of criminal and regulatory proceedings for the defence and prosecution in equal measures, as well as public inquiries and proceedings in the Administrative Division of the High Court.

John is well-versed in the practical and technological demands of complex investigations. He has been at the cutting edge of the use of technology in big data investigations for over a decade—including AI-driven analytics in support of enforcement and compliance outcomes—and has mastered strategies to defeat opponents’ data handling and review procedures. John’s strategic approach helps clients manage sensitive matters discreetly while anticipating regulatory trends and preserving commercial objectives.

He frequently delivers speeches and serves on expert panels at international forums addressing economic crime, corporate accountability, and emerging enforcement priorities worldwide.
