Mark Leftly: Supermarkets' jargon can't hide problems

Outlook For places that you visit to simply do the weekly shop or pick up a quick ready-meal, supermarkets don't half get caught up in increasingly irritating technical jargon. Today, Sainsbury's followed Morrisons in harping on about its "multi-channel strategy", while the third of the big three, Tesco, will also use the incredibly ugly "like-for-like sales" phrase today.

All this horrible language ends up making the big supermarkets sound like they've got something to hide. And, just maybe, they have: ultimately, there's nothing much to choose between them in terms of growth and there won't be for the foreseeable future.
