Sir; The news that Sainsbury's rivals have hit out at the Stamford street multiple for so called gun jumping on the trading code issue made interesting reading (The Grocer, last week). Tesco, Asda and the rest may be miffed that Sir Peter Davis went public on the matter without consulting them, but may I, as an ex-Sainsbury employee, express my delight. If, indeed, Sir Peter and trading director Stuart Mitchell have raised the hackles of the opposition, then many congratulations to them. For too long Sainsbury has lagged behind the other majors when it comes to enterprising PR initiatives, so this has come as a breath of fresh air. Let's have more, Sir Peter!
