Is the success of the big supermarkets to blame for the demise of our town centres? Gary Robertson takes your calls. Tesco has just announced record profits, but has this come at a cost? Do you shop at one of the big supermarkets? Has your town centre gone downhill as a result of the dominance of the the likes of Tesco, Asda and Sainsburys. It does seem ironic that while many complain about the effect they have on local areas so many people still shop there, contributing to their success. Gary Robertson takes your calls, texts and emails.
