Asda has grabbed a record share of the grocery market, according to the latest figures from Kantar Worldpanel.

For the 12 weeks ending 18 March, Asda’s share was 17.9%, a year-on-year growth rate of 7.8%.

Kantar director Edward Garner explained Asda’s strong showing was largely down to the full integration of its Netto stores.

Tesco continued its recovery since the start of the year, although its growth rate of 2.7% still “lags behind the market” said Garner.

The Co-operative Group, which reveals its full year results on Thursday, suffered a slight fall in fortunes, with its till roll down 2%, taking its share from 6.9% a year ago to 6.5%.

Both Sainsbury’s (16.6%) and Morrisons (12.3%), saw their share remain unchanged year on year.

Waitrose, Aldi and Lidl continue to out-perform the market, with Aldi achieving year-on-year growth of 28.5%.

There was also good news for Iceland, which in a buoyant frozen food market, saw 10.2% year on year growth.
