In 2011 he was admitted as an attorney of the Bar of the Turks and Caicos Islands specifically to advise on a massive-scale corruption enquiry and prosecution. His extradition practice has involved successfully advising overseas governments on requests for fugitives in third countries, and defendants in high-profile requests for extradition from the United Kingdom.

His technical expertise means that he can also provide advice to individuals and companies having to deal with prosecuting agencies in relation to cybercrime allegations. As a result of his knowledge of the new ‘Deferred Prosecution Agreement’ scheme introduced by the 2013 Crime and Courts Act, he has been invited to lecture on the procedure, and has written an article considering practical issues raised by it. His criminal defence work has involved working with professional white-collar clients such as solicitors and directors charged with large-scale fraud and other serious offences.
