Criminal litigation.


David has an extensive criminal litigation background. Regularly acting for individuals and companies in high profile cases, he specialises in providing advice at the crucial early stages of an investigation. Astute and practical in his approach, David’s early involvement in the case can make the difference between being charged with an offence or not. This includes representing clients who are arrested and interviewed under caution, challenging search warrants and other investigatory powers and making pre-charge representations to the police and prosecuting authorities. Should matters progress to court he is meticulous in his preparation and has a high acquittal rate. Case highlights include representing Cambridge Analytica’s CEO in the Facebook data breach scandal and other high profile matters.

David’s white collar crime practice includes acting for companies and individuals accused of complex financial investigations involving fraud, overseas corruption and Mutual Legal Assistance (MLA). He specialises in defending tax evasion/fraud allegations brought by HMRC and has developed a specialist expertise in advising in cross border tax litigation involving MLA requests between Member States. He is currently representing two separate companies in the on-going “cum ex” trading scandal in Denmark and Germany.
