Chief executive, University College London Hospitals Foundation Trust (2010 ranking: 31)

With SHAs dying and the regional arms of the commissioning board inchoate, academic health science centres and the trusts that form their base are more influential than ever. None has a higher profile than UCL Partners and its bedrock trust University College London Hospitals.

Sir Robert Naylor’s trust scored another notable victory with the success of hyper acute stroke units - a model that is being exported nationwide. With that, the outflanking of the Royal Marsden in a bid to bring proton beam therapy to the UK, and the expansion of UCLP to Essex and beyond, a continuing influence is a sure thing.
