BUSINESS CRIME AND FRAUD
SFO v. D and Others (2024)
Instructed to defend a military telecommunications specialist alleged to have been involved in bribing Saudi Royalty and Officials in return for the purchase of military telecoms and support systems for use by the Saudi Arabian National Guard. This was an ultra-high profile and politically sensitive SFO prosecution involving a defence that asserted high-level UK Government authorisation for the allegedly corrupt payments. Mark’s client had the case against him dropped by way of the grant of a ‘nolle prosequi’ following detailed representations advanced in the final lead up to the first of two lengthy trials.
R v. Nethercott (2023)
Instructed to defend an ex-finance director of the post office in relation to allegations of tax fraud over many years.

At the follow-on trial Mark’s client was unanimously acquitted.
R v. Moore and Others (2022)
Instructed to prosecute investment and mortgage fraud. The case was highly unusual as the defendants initially had all pleaded guilty but later had their convictions quashed by the court of appeal, who sent the case back to the Crown Court. Mark was then instructed to prosecute the trial that followed and secured across the board convictions.
R v. Patel (2022)
Instructed to defend a highly complex private prosecution for forgery and fraud. The company law aspects of the case were so involved that a specialist companies court judge was drafted in as the trial judge.

Mark has specialist expertise in relation to private prosecutions.
SFO v. K (2021)
