I am a solicitor advocate: I'm just as at home in the High Court as I am in the Magistrates' Court.I have considerable experience in defending clients facing all manner of criminal prosecutions. I am recognised as an expert in white collar crime and road traffic prosecutions. I am a founding and executive member of the Association of Motor Offence Lawyers. I also lecture on road traffic law and appear in the news media.
I am often the solicitor of choice in relation to high profile cases where clients not only require the highest level of skill but also discretion. I was involved in the cash for peerages investigation and the investigation by the City of London Police in relation to corrupt practices in professional football. I represented Sean Hoare in the News of the World phone hacking investigation until his untimely death and I advised other suspects in the Metropolitan Police Elveden and Weeting investigations respectively into phone hacking and corrupt payments to public officials.
In the field of fraud, I have acted in a number of VAT carousel fraud cases, most recently R – v – W and another in which myclient was acquitted of cheating the revenue. My client in Operation Euripus (said by HM Revenue and Customs to have been the largest ever carousel prosecution) was discharged following a successful dismissal application. Following the dismissal application, the prosecution sought to obtain a voluntary bill of indictment in the High Court. That application was defeated.
Together with colleagues, I am currently representing a defendant in Operation Bulkhead – a prosecution of participants in what HM Revenue and Customs allege is a £125 million fraudulent tax avoidance film scheme. Read more
I also head the team representing a defendant in Operation Hornet – a prosecution by Thames Valley police concerning an alleged fraud on HBOS running to many tens of millions of pounds. Read more
I represented the former Chief Executive of Ujima Housing Association who was alleged to have conspired with others to defraud Ujima of more than £1 million. After a trial lasting over 3 months, my client and his co-defendants were unanimously acquitted.
In general crime, my client in an extremely grave sex crime case was unanimously acquitted in a matter of minutes following a 5 week trial at the Crown Court. Read more
In recent times, my clients have been acquitted in cases involving allegations of death by careless and/or dangerous driving at the Leeds, Wood Green, Exeter and Isleworth Crown Courts. I also undertake less serious road traffic cases, in which clients are frequently seeking to avoid disqualification. If appropriate, I will take the case all the way to the High Court. Read more
In addition to pure criminal practice, I have considerable experience in relation to cash seizure, confiscation and asset recovery proceedings.
I undertake inquest and regulatory work. I was one of a team of lawyers from Sonn Macmillan Walker who worked on the 7/7 bombings inquests.
