Tesco is "well-positioned to maintain market share… generate enough cash to fund [capital expenditure] and shareholder returns", it said. Kantar data from 3 October shows the grocer accounts for 27.4 per cent of grocery sales in the UK. Catherine Shuttleworth, founder of retail agency Savvy, stressed that Tesco's Aldi Price Match was a key reason for its success. "Tesco reassured people that shopping with them means you can have all the benefits of Aldi pricing with all the benefits of the Tesco range," she told the Retail Gazette yesterday.
