Asda added that total sales increased in the high single digits during the period and market share rose 0.3% year-on-year in the 12 weeks to April 20.
Chief executive Andy Bond said: "It's at times like these when Asda's values really come into play. Our role to help give customers good quality products at affordable prices is more important than ever before. Whilst today's results are encouraging, we mustn't become complacent, especially in the current economic climate. We have a duty to lock down inflation by working with our suppliers, to cut costs to ensure that our customers are always getting the best possible deal on their weekly shopping."
