Evan Davis 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?

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. Show less
