We are thrilled to be featured in Global Investigations Review’s GIR 100 2025, an annual guide profiling the world’s leading firms in high-stakes corporate investigations. We are also proud to have been shortlisted for Boutique or Regional Investigations Practice of the Year at the GIR Awards 2025. This recognition underscores our expertise in conducting, defending, and advising on complex cross-border investigations.

GIR describes Peters & Peters as “one of London’s best-known firms for business crime, fraud and investigations work and a pioneer in the practice.”

GIR highlighted recent work including:

• • Acting for Eugene Shvidler in the UK’s first sanctions delisting challenge, culminating in a landmark Supreme Court judgment.
  • Advising Paul Bell, an Isle of Man entrepreneur, in multijurisdictional VAT fraud proceedings.
  • Representing John Dance, founder of WealthTek, in major regulatory and civil proceedings brought by the FCA.
  • Advising former UK Prime Minister Boris Johnson in the Covid-19 public inquiry and Privileges Committee investigation.
  • Acting for the Post Office in the public inquiry into the Horizon scandal.

GIR notes the firm’s “global experience, financial sophistication and highly forensic approach, grounded in the exacting demands of criminal law. Testimonials featured in the report highlight that Michael O’Kane “sets the tone with his creative thinking, forensic application and easy manner with a wide range of clients” and Kerri McGuigan and Liam Lane “provide high-powered, no-nonsense support.”
