The view from the top of business. Presented by Evan Davis, The Bottom Line cuts through confusion, statistics and spin to present a clearer view of the business world, through discussion with people running leading and emerging companies.

This week Evan asks his panel of top executives about the perils and the possibilities of running a fast-growing business. Many a company has spiralled out of control because of a failure to manage rapid growth - but what are the speed limits? They also chew over the role of the business lunch.

Evan is joined in the studio by Clive Schlee, chief executive of sandwich retail chain Pret A Manger; Peter Bamford, chairman of SuperGroup, the fashion retailer behind the SuperDry brand; Giles Andrews, founder and chief executive of Zopa, an online lending service.
