Rob is a highly experienced barrister and advocate practicing in competition law, procurement law, public law and other regulatory litigation. He acts for the range of commercial and public sector clients.

Since 2015, Rob has been Standing Counsel to the Competition and Markets Authority.

Rob’s work is principally divided between the High Court and the Competition Appeal Tribunal, and he appears frequently in the appellate courts. Rob has appeared in many of the leading cases in competition and public procurement law.

Before joining Monckton Chambers, Rob worked as an in-house advocate at a large City law firm. His experience has given him a particular insight into the needs of both solicitor and lay clients at all stages of the litigation process, and as a result, Rob places particular importance on being user friendly and accessible.


Called 2000, Middle Temple. Rob has a first class law degree and a postgraduate BCL degree from University College, Oxford. On graduating, he worked as a research assistant to the Law Commission for two years, following which he was awarded a Jules Thorn Scholarship by Middle Temple. In 2000, Rob was called to the bar and started his career at Keating Chambers. After a number of years in practice, he joined Denton Wilde Sapte’s Advocacy Group, the first and longest established ‘in-house chambers’ in the City. He joined Monckton Chambers in 2006. Rob has tutored at University College, London, and has written and lectured on a wide range of legal subjects. In 2002, he was the judicial assistant to Lord Phillips MR (as he then was).
