The founder of Richer Sounds is one of the UK's leading lights of responsible capitalism - in this interview with Mary, he takes us through the way he has run his business, why he decided to give control to his employees, and the launch of the Good Business Charter.

Elsewhere in the last episode of this series, we join Mary and colleague Emily Bryce Perkins (Portas Agency's culture director) at the firm's Christmas party preparations, and reflect on a decade of change in UK retail and culture.
