Asda shows worst sales performance in 20 years

Tesco's resurgence and a bitter price war fuelled by competition from Aldi and Lidl lead to three-month sales fall of 2.1% at Asda

Asda has sunk to its worst sales performance in more than 20 years in the face of a resurgence by its larger rival Tesco and a bitter supermarket price war.

Tesco increased sales by 1.1% in the 12 weeks to 1 March, its best performance in 18 months, while sales dropped at all three of its major rivals, according to the latest data from Kantar Worldpanel.
