David Owen is one of the more fascinating figures to have inhabited British politics over the last four decades. Promoted to foreign secretary by Labour prime minister Jim Callaghan at an absurdly young age, and one of the founder-members of the SDP (before splitting that party as well), he was potentially the best leader the Tory Party never had.
He's also, of course a doctor, and his most recent book, In Sickness And In Power (Methuen), combines his twin interests in medicine and politics - an account of how ill-health impacts upon the behaviour of world leaders, and thereby influences the course of world history.
It's a fascinating subject and you can hear him discussing it with the very wonderful Tim Haigh here: Tim Haigh Reads Books.
This is the first of a new series of podcasts from Green-Shoot.com. It's much recommended (and not simply because I'll be turning up in a later podcast).
