Sir William Patey – British Ambassador to Kabul, 2010-2012 (Retired)

Stephen Sackur speaks to a brilliant heart surgeon - veteran of more than 30,000 operations - but his growing international reputation rests less on his medical skill, more on his business brain.

He's building what he calls medical cities across India and beyond - but can this vision of delivering a public good for private profit really change healthcare around the world?
