Evan Davis tests his three guests on the tricky business of succession: is there an ideal time to choose who is going to take over from you, or is it better to hang on until you're pushed?

Evan's guests are Jens Hofma, chief executive of Pizza Hut UK, Chris Hyman, chief executive of Serco and Harriet Green, chief executive of Premier Farnel. Show less
