Jonathan Mann QC has long specialized in representing those charged with fraud, confiscation, forfeiture and seizure of assets, as well as those accused of grave offences of violence, serious and historic allegations of sexual abuse, and serious organised crime conspiracies.

He has considerable experience acting for those accused of serious and complex financial crime, as well as regulatory infringement. He advises, pre-charge, those being investigated by both domestic investigators as well as those with international jurisdiction. Most recently, he has advised and represented an individual under investigation by the Bank of England for his alleged involvement in LIBOR price rigging. In the last few years he has been instructed to represent individuals charged with bribery, those charged in missing trader frauds (both within the context of criminal trials and at VAT tribunals), defendants investigated and prosecuted for insider dealing, as well as a legal professional charged with defrauding HM Land Registry. He also has represented a number of individuals investigated by HMRC in their operations to recover taxes fraudulently diverted within the construction industry allowance scheme.

In addition to his financial crime practice, he also defends cases of serious crime, including a proof of life/missing body murder, an allegation of historic abuse in a school for disabled children and a Triad blackmail and money laundering prosecution. He is also regarded as having a particular expertise in defending in cases where the accused is mentally ill, where there are potential defences of insanity or where the defendant may be unfit to plead.

He was a member of the Criminal Bar Association committee that drafted the Bar’s response to the government’s Green Paper dealing with defendants with Psychopathic Disorders. He was a member of the Sentencing Advisory Panel in 2011.

He was appointed a Recorder of the Crown Court in 2012, and appointed Queen’s Counsel in 2015.

He is ranked as a leading silk in the Legal 500 (2017) in both Crime and Fraud.
