Tesco and Asda continued to underperform the market in the latest grocery figures from Kantar Worldpanel.

For the 12 weeks to August 8, Tesco and Asda saw a dip in their share by 0.2% and 0.3% respectively. By contrast, Sainsbury’s and Morrisons both increased their market share by 0.2%.

Kantar said the whole market saw healthy growth up 4.5% boosted by food price inflation which crept up again in August for the third month running.

Edward Garner, communications director at Kantar Worldpanel, said: “Morrisons in particular has shown a strong performance this month.  Despite some commentators expecting the Morrisons growth to run out of steam it still comfortably leads the top four in terms of year-on-year performance with growth of 6.9%.”

Despite Aldi experiencing a boost in the last couple of months, the discounters as a whole are still struggling to increase their share of consumers’ wallets, with their total market share remaining at 6% for the last two years.

The Co-op’s market share has increased from 5.5% to 6.4% in the period, as it continues to rebrand Somerfield stores to Co-op.

Food inflation for the period was 2.2%.
