Head of the London Global Disputes practice, Sion Richards is a highly active partner engaged in multijurisdictional investigations covering fraud and corruption. A key contact for financial institutions and corporates, Adam Brown’s recent mandates include high-profile proceedings concerning misfeasant trading, while Alex Chalk KC, who joined the firm in early 2025, is highly experienced in criminal investigations involving the SFO and the FCA. Dual-qualified (English and French) Karl Moussalli is also recommended.
