With a strong global platform, particularly within the US, Africa, and Asia-Pacific, Mayer Brown International LLP is well-placed to handle cross-border internal and regulatory investigations, compliance reviews, and criminal defence cases, regularly representing clients throughout SFO and US DOJ proceedings, as well as before regulators globally. The London-based team was strengthened in October 2021 with the transfer of counsel Liang Pu, who brings significant Chinese law expertise and experience in global bribery proceedings, from the firm’s Hong Kong office, and the recruitment of financial services ESG and risk specialist Musonda Kapotwe from an in-house position. They join a practice overseen by Alistair Graham, who has a strong record in defending global businesses in significant criminal proceedings, and also features Sam Eastwood, who focuses on compliance advice and has acted as an independent monitor to the SFO, World Bank, and African Development, and US-qualified Jason Hungerford, who advises clients facing sanctions-related investigations by global enforcement agencies.
