James Nash

James appears regularly in serious criminal trials on behalf of the defence and the prosecution, including in private prosecutions.

He has acted in cases of serious violence, fraud by abuse of position, drug trafficking (including modern slavery), robbery and sexual assault in the Crown Court and the Court Martial. His background and experience mean that he is well placed to handle complex and sensitive document-heavy matters at short notice.

As well as his criminal practice, James accepts instructions in regulatory and professional disciplinary matters. He has prosecuted on behalf of the General Osteopathic Council, and appeared as a defence representative before the Nursing & Midwifery Council. He has been seconded to the Bank of England to assist in successful enforcement proceedings against a Category 1 bank.

Before coming to the Bar, James qualified as a Chartered Accountant at a Big 4 firm, specialising in external financial audit of large listed companies. He also spent some years working as a senior group financial accountant at a leading healthcare group, ensuring regulatory compliance and working on a major restructuring programme.
