Discounters Aldi and Lidl hold their share of market
Half of households shopped at Aldi or Lidl at least once over the summer as the discounters kept up their pressure on the "big four" supermarkets.
Latest till-roll figures from Kantar Worldpanel reveal that supermarket price inflation fell for the 11th quarter in a row to stand at 0.2% in the 12 weeks to August 17, leaving overall sales growth at another 10-year low of 0.8%.
Discounters Aldi and Lidl held their record market shares of 4.8% and 3.6% respectively in the period, with 53% of households shopping at either outlet.
Asda was the only one of the big four chains to boost market share, with Tesco and Morrisons remaining under pressure and Sainsbury's suffering a small drop to 16.4% as its sales growth lagged behind the market at 0.3%.
The country's biggest grocer, Tesco, suffered a 4% sales fall, the largest decline among the big four. Its market share fell to 28.8% from 30.2% over 12 months.
Morrisons, which in March pledged to spend £1bn cutting prices over three years, saw its sales fall 1.9% and its market share slip to 11% from 11.3%.
