Anthony has specialised in all aspects of clinical negligence and personal injury litigation for nearly 20 years. His exclusively claimant based clinical negligence practice includes claims for cerebral palsy and other birth related injuries, negligent surgery (including laser eye surgery and cosmetic surgery), hospital-acquired infection, anaesthetic awareness, delayed diagnosis of cancer and critical ischaemia. 

Anthony's personal injury practice involves high value cases generally arising from accidents at work and road traffic accidents acting for both Claimants and Defendants. Many of his cases involve complex medical and engineering evidence.

Anthony undertakes a significant amount of fatal accident work and as a result appears at inquests on a regular basis. He has particular expertise in this area having been instructed by the Treasury Solicitor as junior counsel to the Shipman Inquiry and more recently by the Senior Coroner for Manchester as counsel to the inquest into the death of Stephen Hunt, a serving fireman with Greater Manchester Fire and Rescue Service who died during active service.

Anthony has been ranked in the Legal 500 since 2007 and earns considerable praise in the 2017 edition of Chambers & Partners for his claimant clinical negligence practice.
