Actions

I am a highly experienced junior, with a practice including leading in significant complex, multi-defendant cases. I have featured annually as a ‘Leading Junior’ in Chambers and Partners for many years, reflecting my high standing amongst instructing solicitors and their clients.
I have appeared for both prosecution and defence, concentrating more recently in representing defendants in serious crime, in courts throughout England, and so have extensive experience in the complexities of the developing areas of criminal law.

I have led in multi and single defendant murder trials, substantial fraud and money laundering trials, and other categories of serious crime such as drugs importation and supply, and vehicle related crime, over recent years. This has meant that I have developed the ability to recognise the tactical requirements in a huge variety of different situations within both single defendant and multi defendant trials. In combination with the ability to assimilate and understand the significance of vast quantities of documentary exhibits, which are a characteristic of modern trials, I am equipped to deal with the requirements of representing lay clients who face long and complex trials.

I have led, and been led, in many murder cases, ranging from gangland executions to sexually motivated killings, and those with special defences such as provocation and diminished responsibility.

I have led in very complex fraud and money laundering cases, including defendants who were professionals, such as solicitors and chartered accountants, and so have an understanding of the practices involved. I am computer literate; an essential attribute in preparing and presenting such cases before the courts. I have been instructed in cases involving bureau de change, where substantial sums were said to be paid through such organisations in order to launder the proceeds of crime by conversion between currencies.

I pride myself on thorough preparation, and the ability to communicate effectively, and sympathetically, with lay clients from all backgrounds, which I have always believed to be an essential element of the task of the barrister.
