View moreJohn is a junior barrister specialising in commercial and business and property work. His practice spans commercial disputes, civil fraud and asset recovery, insolvency, company and trusts litigation, with a particular emphasis on high-value, multi-jurisdictional disputes involving allegations of dishonesty.
Since joining Chambers in September 2022, John has been instructed in some of the heaviest litigation before the English courts. He acted (led by Tim Penny KC) for two defendants to PIFSS v Al Wazzan & ors, a US$1.1bn Commercial Court bribery claim whose 40-week trial is said to be the longest in modern Commercial Court history (judgment awaited). He is currently instructed in Re Windward Prospects Ltd, defending a company’s former directors against a £150m claim for transactions at an undervalue and misfeasance now pursued by BAT Industries Plc, which is to be tried together with BAT’s related claim against S&W Partners LLP.
Alongside his led work in substantial litigation, John has a busy practice in his own right, appearing regularly as sole counsel in the High Court and County Court, including at trial. He is used to acting under pressure and at pace, whether as part of a large counsel team or alone, and strives to be commercial, responsive and easy to work with.
Before coming to the Bar, John completed an LLM at UCL, having previously undertaken the GDL and Bar Course at City, University of London. He also spent two years at EY in its Corporate Governance team, giving him insight into the issues that underpin much of his company and insolvency work. A linguist by background, John is proficient in Italian and Spanish.

Commercial disputes
John acts in a wide range of commercial disputes, from the very largest Commercial Court litigation to sole counsel trials and applications. He has particular experience of claims involving allegations of dishonesty, of banking and consumer credit disputes, and of matters raising issues of financial services regulation, including under FSMA and the FCA rules.
