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.

In the week that former BP boss Tony Hayward admitted the company had been unprepared for the Gulf of Mexico oil spill in April, Evan and his panel of top business executives consider how companies plan for unexpected events. How prepared actually are they for a crisis or a disaster?

And dressing up, dressing down, power dressing, smart casual - they also discuss what to wear at work.

Evan is joined in the studio by Neil Gaydon, chief executive of set-top box maker Pace; Sara Weller, managing director of retail chain Argos; Richard Reed, co-founder of Innocent Drinks.
