Of every £8 spent by British shoppers in any shop, anywhere, £1 of it will be making its way to Tesco. Tesco will sell £30 billion of goods this year in Britain - more than double either of its nearest rivals, Sainsbury's and Asda.

If Tesco were a nation it would be the 74th biggest economy in the world - bigger than Libya or Kuwait. Tesco buys nearly one third of all produce from British farms. Sir Terry Leahy doesn't appear to have lost any of his ambition, telling Management Today magazine this year that Tesco still had only 6.5 per cent of the non-food market and that £1 in every £8 spent was not enough. He said: "Our market share of UK retailing is 12.5 per cent - that leaves 87.5 per cent to go after." You have been warned.
