Sales at food retailers are showing robust growth, while the decline in the fortunes of non-food retailers continues, according to figures released by TNS Worldpanel today for the 12 weeks to May 18.

Overall, grocery sales rose 6.6 per cent over the period, from£19.27 billion to£20.53 billion, in sharp contrast with a 3.5 per cent fall in non-food sales, from£8.11 billion to£7.82 billion.

The highlights were to be found among the discounters, with Aldi increasing its market share from 2.5 per cent to 2.8 per cent – a 15 per cent hike. Lidl also performed strongly, with a 9.6 per cent uplift in its share.

Among the big grocers, Tesco’s market share remained static at 31.1 per cent and TNS noted modest increases in share for both Morrisons and Asda. Sales at Sainsbury’s rose 4.6 per cent, but its market share declined from 16.3 per cent to 16.0 per cent.
