Gareth routinely advises both regulated and non-regulated businesses on anti-money laundering, bribery, and sanctions issues and he is experienced in handling complex internal investigations and regulatory and criminal self-reporting in these areas.

In addition to his criminal and regulatory investigations and litigation experience, Gareth has a burgeoning commercial litigation practice, where his focus is on assisting both regulated and non-regulated clients to investigate instances of internal fraud, including push payment and business email compromise.

Gareth is increasingly engaged to advise on strategy for both investigating such situations and seeking the recovery of funds, whether from fraudulent account operators or via the relevant financial institutions including utilising the Court's Norwich Pharmacal and Bankers Trust jurisdiction to provide victims of fraud with access to information held by relevant third parties via Orders to compel its production. Where such matters – and others Gareth is involved in – proceed to settlements, he has gained substantial experience in drafting and negotiating such agreements.
