Asda’s share of the grocery market has dipped for the 10th consecutive report, with sales growth lagging behind the other major grocery retailers.

According to Kantar Worldpanel, for the 12 weeks ending 3 October, Asda reported growth of just 3.2% and a market share of 17.1% of all till receipts, compared with 17.2% for the same period in 2009.

Overall growth in the market at 4.1% remains ahead of grocery inflation at 3%. Kantar Worldpanel said that, regardless of fears about food inflation, it still expects the rate to be held around 4% by the year end.

Tesco maintained its share of the market, at 30.9%, while Sainsbury’s had the best quarter among the top four supermarkets, up from a 15.7% share of the market in 2009 to 15.9%. It is the 20th consecutive time that Sainsbury’s has seen its share of sales grow, according to Kantar Worldpanel’s figures.

Waitrose appears to be seeing the benefits of its Tesco price-matching campaign, which launched on September 27. Its share of the market rose by 0.2 percentage points year-on-year to 4.2%, with sales growth of 9% to £912m.

Kantar Worldpanel communications director Edward Garner said: “Asda continues to see its share under pressure with a drop of 0.1% but this is better than in previous months and we are currently seeing the re-launch of Asda’s core own-label range through the ‘Chosen by You’ campaign.”

At the discount end of the market Aldi maintained its 3% share of the market, with sales up by 3.4% year on year to £645m, while Lidl saw sales rise by an impressive 5.9% to £523m, its share of till sales remaining steady at 2.4% of the total.
