Why did Safeway's UK supermarkets disappear?

Safeway was once one of our biggest supermarket chains, so why did it drop down the list of top performers before disappearing altogether?

The BBC Business journalist, Sean Farrington, looks into it and speaks to the former Safeway director, Teresa Wickham, a former Safeway supplier, Judy Garner, and the News Editor, Ronan Hegarty, from The Grocer magazine.

Alongside them all to analyse Safeway's fortunes is the self-made millionaire and serial entrepreneur, Sam White.

This episode was produced by Viant Siddique.
