After recent corporate scandals like VW's emissions' cheating, Tesco's accounting irregularities, Barclays interest-rate rigging, many asked why company board members failed to act. What happened to the checks and balances designed to curb management excesses? Evan Davis and guests look at how company boards operate and how to make them work effectively. They discuss the role of company directors, the skills and experience required and examine why some say 'Beware the charismatic CEO'.

Guests:

Michael Jackson, Former Chair, The Sage Group plc

Margaret Heffernan, Former CEO, entrepreneur and author

Producer: Sally Abrahams.
