Discount operators Aldi and Lidl are growing market share to the detriment of the UK’s second-largest grocer Asda, according to the latest figures from Kantar Worldpanel.

Aldi and Lidl have grown their sales by 18% year-on-year and, for the 12 weeks ended 12 June, they held their “all-time record shares” of 3.4% and 2.6%, respectively, Kantar said. Asda saw its market share fall from 16.7% this time last year down to 16.3%.

Meanwhile, upmarket retailer Waitrose saw sales rise 8.9% year-on-year to reach market share of 4.3%.

Commenting on the success of retailers at both the premium and discount ends of the value spectrum, Kantar Worldpanel communications director Edward Garner said the “two nations effect continues unabated”, and that there is further evidence for this trend through the double-digit growth of Tesco’s Finest range.

He said shoppers were adopting coping strategies such as “taking advantage of promotional offers or topping up at the discounters” but insisted there was “no sign of a return to the rapid growth of budget own-label ranges that we saw in 2008.”

The market shares of Tesco, Sainsbury’s and Morrisons remained relatively constant over the period at 30.9%, 16.2% and 12%, respectively.
