Prior to taking silk this year Leon Kazakos was shortlisted for Crime Junior of the Year 2019 and ranked Band 1 for Crime as a leading individual by Chambers and Partners.

His practice divides into business crime, general crime, regulatory proceedings, tax appeals and police disciplinary work.

In business crime he is instructed to defend across the spectrum of misconduct; from allegations of high value fraud, corruption and misconduct in public office to cheating the public revenue, money laundering, breaches of FSMA, and other related misconduct.

His general criminal practice encompasses homicide (murder and manslaughter), human trafficking and slavery, serious drugs and firearms offences, and serious sexual offending.

His regulatory work spans firearms licensing, breaches of planning notices, wildlife offences (CITES regulations) and some health and safety work.

He provides advice and advocacy in substantial, sensitive and complex cases usually from a pre-charge stage; representing individuals and companies who are under investigation or being prosecuted for serious wrongdoing. He is an accredited advocacy trainer (Lincoln’s Inn), a pupil supervisor and a trained facilitator for advocacy and the vulnerable. Leon lectures and delivers training to solicitors’ and accountancy firms in relation to criminal and regulatory matters, with a particular focus on financial misconduct and money laundering.

He is a contributing editor to Butterworths “Fraud Law, Practice and Procedure” and a contributing author in corporate crime to LexisNexis.
