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. The programme is broadcast first on BBC Radio 4 and later on BBC World Service Radio, BBC World News TV and BBC News Channel TV.

Evan and his executive guests discuss the evolution and hierarchy of brands. Who has the upper hand in the many battles being fought between big consumer brands and shops' own-labels? They also consider consumer tastes - do their own customers have good taste, or do they just buy what they're given?

Joining Evan in the studio are Justin King, chief executive of supermarket chain Sainsbury's; Cecile Bonnefond, chief executive of French champagne house Piper-Heidsieck; Geoff Cooper, chief executive of builders merchant Travis Perkins.
