HARDtalk - William Hopper

William Hopper is an investment banker, a former Conservative MEP and one of the founders of the Institute of Fiscal studies. At the age of 78 he and his brother Ken have written a book which has shot into the FT top ten of books about business. Called 'The Puritan Gift' it attacks the cult of professional management and blames the trend towards industry leaders with management degrees rather than knowledge of their industry for current crises in the American economy. He talks to Stephen Sackur.
