In this episode we were joined by Tom Watson, the Deputy Leader of the UK Labour Party who only recently stood down at last year's general election. He is now the author of a new book Downsizing: How I Lost 8 Stone, Reversed My Diabetes and Regained My Health, and in this wide-ranging interview with Ros Urwin he talks about his successful battle against obesity and diabetes, what this might mean for the global obesity epidemic, and how Labour might become electable again.  Support this show http://supporter.acast.com/intelligencesquared.
