He has experience across a range of offences including: dishonesty, drugs, domestic violence, motoring, sexual offences, firearms and fraud. Matthew is currently instructed in a number of Crown Court trials covering offences from malicious communications to weapons and assault offences.

Matthew also has a developing prosecution knowledge of financial criminal investigations through his current instructions for the Serious Fraud Office advising on disclosure and relevance on a fraud and money laundering case.

Since Matthew started practising at the Bar, instructing solicitors have remarked that they “trust him to offer sound advice and build excellent rapport with clients”. Matthew has also earned praise from a senior circuit judge, being described as “confident, clear and concise...he is the sort of barrister judges welcome having before them, which can only be to the advantage of his clients”.

Whilst a pupil at 9BR Chambers, Matthew assisted senior members of chambers in a number of complex and high-profile cases, including: murders, serious sexual assaults, rape & multi-million-pound VAT fraud.

Prior to being called to the Bar Matthew served as an army infantry officer; service which included overseas operational deployments. Utilising this experience, he maintains a strong interest in areas of military law, court martial, as well as firearms cases and private firearms licensing appeals; recently delivering a webinar on firearms law and new Sentencing Council Guidelines on firearms offences.

Matthew has also worked in the front office of a tier 1 investment bank, in an FCA registered position. He is therefore well placed to develop his financial crime and regulatory practice.

Matthew has experience in presenting cases for the Nursing & Midwifery Council.
