Overview

Alexander is an experienced and passionate criminal defence barrister. He has a busy practice in the Crown Court. 

He is an expert in military law, he speacialises in Court Martials, and the Service Justice System.

He regularly advises members of the Armed Forces in relation to both professional matters (Major Admin Action, Service Complaints) and CDT fails (excessive alcohol/drugs outside the normal range).

Criminal Defence

Alexander represents clients in the most serious and complex criminal cases. 

Prior to being called to the Bar, Alexander was a solicitor for 15 years and a Higher Courts Advocate for the last 13 years.  As a result, Alexander has gained a wealth of experience that means he is ideally placed to advise solicitors on case preparation in order to achieve the best possible outcomes for his clients. He understands the professional stresses and strains of being a solicitor, having practised as a solicitor and higher rights advocate for a number of years.  With this powerful knowledge, he is able to reduce the heavy burden on criminal defence solicitors, for the benefit of their client. 

He enjoys interacting with clients and building trust and a rapour so that he can robustly represent them. 

He is equally as comfortable being led as he is acting as a Junior alone. His extensive experience in lengthy multi-handed cases has allowed him to develop and grow as an advocate in front of judges and juries alike. 

He is meticulous in his preparation for each and every hearing, understanding the importance for the client and the impact of the outcome on his client. 

  • He has a particular interest in cases involving Gangs and has represented numerous defendants in a variety of cases ranging from murder to drug Supply. 

  • He also has a very good understanding of Firearms legislation.   

Alex also specialises in military law.

  • He is instructed in cases involving the Service Justice System and regularly advises members of the Armed Forces in relation to both professional matters (Major Admin Action, Service Complaints) and CDT fails.

He represents his clients in Court Martial hearings (within the United Kingdom or in a different jurisdiction). He was trained by the now-retired Gilbert Blades and maintains the same approach to defending military personnel.  

Additional Information

  • Alexander completed a Degree at the University of St Andrews in Medieval History before completing his Law Conversion Course at the University of Law in York.  
  • He has subsequently worked at 3 of the largest firms providing Criminal Defence in both Lincolnshire and London before he decided to become a Barrister in July 2025.
