Only one of the U.K's biggest retailers gained market share in the ultra-competitive Christmas sales period with discount stores getting a big festive bonus, according to the latest industry figures.
The figures, from Kantar Worldpanel for the 12 weeks ending January 3, showed no Christmas uplift for the British grocery market as a whole as consumer spending 0.2 percent on last year, thanks to falling prices.
Discount retailers such as Lidl and Aldi, as well as premium brand Waitrose, the Co-operative and Sainsbury's "successfully grew ahead of the market and were the share winners over Christmas," the consumer data researcher said.
"Its premium Taste the Difference brand posted its biggest ever Christmas sales and promotional efforts were concentrated on simple price cuts rather than complicated multi-buy deals. This helped attract an additional 114,000 shoppers, with sales increasing by 0.8 percent on last year."
In the same period, Tesco sales fell by 2.7 percent from the same period a year before. Asda's sales fell 3.5 percent and Morrisons' declined 2.6 percent, according to Kantar.
