He advises and represents prosecuting authorities and defendants on CJA and PoCA restraint and confiscation issues at all stages of investigation and prosecution and has extensive experience of prosecuting multi-agency litigation.

Since 2014 Mark has been retained by a major bank in respect of consequential loss claims arising out of the FCA review into the sale of Interest Rate Hedging Products. Mark is also presently instructed in the prosecution of a multi-million pound conspiracy to defraud which is likely to result in at least three multi-handed trials.

He is a level-3 CPS prosecutor and approved to prosecute rape and other serious sexual offences. He also defends extradition cases, defends at Courts Martial in the UK and abroad and conducts Judicial Review and appellate work in the Administrative Court and in the Court of Appeal respectively.
