Tesco re-focuses on poor - and posh

Following its Christmas sales trashing, Tesco is overhauling its store offering. Poorer, more hard-up areas will see much more emphasis on 'value', cheaper products while posher areas will have more hoity-toity, upmarket fare on its shelves.

To some degree, Tesco already follows this approach - but it will be more hard-nosed in future. Enough to bring you back from Morrisons/Asda - or Lidl/Aldi?
