The latest grocery market share figures show strong year-on-year sales growth in the grocery sector but food price inflation figures have been over-cooked, claimed TNS Worldpanel.

For the 12 weeks to June 15, the total grocery market grew 6.2 per cent.

Year-on-year growth soared at Aldi and Lidl, up 21 and 13 per cent respectively, giving Aldi a record market share of 2.9 per cent.

Similarly, Iceland continued its strong run with 12 per cent growth as frozen food enjoyed a revival thanks to its strong reputation for value, according to TNS.

Market share at Tesco and Sainsbury’s slipped slightly and their sales growth of 5 and 4 per cent respectively remain behind the market average.

By contrast, growth at Asda and Morrisons continued ahead of the market and both grocers have increased their market share.

TNS Worldpanel director of research Edward Garner said: “Recent media commentary has produced some pretty scary figures for the annual rate of increase of food prices. TNS believes that for the average household shopping basket, taking account of sales levels and promotions, price inflation in grocery stood at 4.6 per cent for the 12 weeks ending April 20.”
