Tesco recovers UK market share The supermarket giant's market share was 30.7pc in the 12 weeks to April 15, compared with the 30.2pc and 29.7pc recorded in the previous two months, according to figures from market researcher Kantar WorldPanel. However, Tesco's share is still below the 30.9pc of April 2011, highlighting the challenge facing chief executive Philip Clarke as he seeks to revitalise Tesco in the UK. Last week Mr Clarke unveiled a "fundamental change" in the company's UK strategy, including fewer hypermarkets. Tesco's market share has been squeezed by low-cost grocers such as Aldi and Lidl as well as upmarket retailers such as Waitrose. Kantar director Edward Garner said: "The discounters and Waitrose are outperforming the middle ground as shoppers polarise their spend. This may also be a result of cutbacks on eating out, which have meant that some shoppers are willing to spend more money on bringing the dining out experience into the home. Asda saw its market share grow year-on-year from 17pc to 17.6pc. However, this was flattered by its purchase of 147 Netto stores. Sainsbury's held its share at 16.6pc, while Morrisons dipped from 12.1pc to 11.9pc.
