Asda vows to cost 10pc less

ASDA has guaranteed to sell 15,000 grocery products at least 10 per cent cheaper than all of its big rivals.

The UK’s second largest chain behind Tesco is promising voucher refunds if customers are charged more.

Asda chief executive Andy Clarke said: “The Asda Price Guarantee cuts through all the phoney claims and headline numbers, and shows when it comes to saving people money, we mean business this year.”

Asda is owned by the US retail giant Walmart.
