He has acted as lead counsel in major disputes, including investment arbitrations in Washington, Stockholm and Paris (ICSID, ECT, BITs) and international commercial arbitrations (eg ICC, UNCITRAL, LCIA, LCIA India, SCC) in seats worldwide. His experience covers finance, insurance, mining, oil and gas, commodities, energy, transport, construction and complex damages issues, as well as public international law.

Graham represents clients at all levels in the English Courts, as well as offshore. He has conducted very long fraud trials, and appeals to the English Court of Appeal, Supreme Court and Privy Council. He has extensive experience of jurisdictional disputes, injunctions, including anti-suit injunctions, and applications for freezing relief, and arbitration-related court applications, including issues of state immunity and recognition.

An independent survey in 2015 found that Graham was the advocate who featured the most often in the Commercial Court in the preceding 12 months. From 2013-2017 he served a four-year term as co-head of Essex Court Chambers.
