I specialise in commercial litigation and arbitration. I head the Insurance and Reinsurance team which mainly represents policyholders and captives in coverage disputes against (re)insurers.

I have over 20 years' experience of litigation, arbitration and mediation in commercial disputes, often with international and civil fraud elements, with a particular focus in insurance and group actions.

My job is to successfully navigate clients to the end of a dispute process as efficiently and effectively as possible.

I primarily act for policyholders in the financial services, pharmaceutical, energy, retail, manufacturing, construction, utilities and transport sectors to recover insurance indemnities properly due under construction all-risks, product liability / recall, professional indemnity, property, business interruption, D&O, employers' liability, public liability, political / credit risk, corporate crime (1st and 3rd party) and cyber / privacy insurance policies.

I also specialise in reinsurance coverage disputes and have acted in leading cases Wasa v Lexington (concerning US pollution losses) and Aioi v Heraldglen (arising from the 9/11 World Trade Centre losses) and currently represent a captive reinsurer in a $500 million LCIA political risk coverage arbitration.

My commercial disputes practice involves both defendant work, such as miss-selling, professional negligence and breach of contract / warranty claims, and claimant work where I have an established expertise in litigation funding, ATE cover and group actions.

I have acted in numerous ad hoc and institutional arbitrations, particularly those governed by the LCIA, ICC and SCC Rules, which has become an increasingly popular option for my clients, especially with enforcement to mind.

Outside of work, I have now firmly hung up my rugby boots, but still love watching rugby and currently coach junior players. I am a passionate free-diver and spear-fisherman, fly fisherman and beekeeper. When my kids allow me time off, I also get involved in various field sports!
