Asda sales have slipped lower in the three months to September after political uncertainty hit consumer spending, the retailer said.
The UK supermarket chain reported a 0.5% decline in like-for-like sales to September 30, as it dipped from 0.5% growth in the previous quarter.
It said that "customers' concerns over Brexit" weighed on the results but hailed "strong" online grocery sales for the period.
Roger Burnley, Asda chief executive officer and president, said: "This quarter has afforded consumers little respite from political or economic uncertainty and this has shown in their spending. However, we have remained focused on doing the right things for our customers.
"We continue to work hard to keep prices low for our customers as well as driving quality and improving our shopping experience.
"I am absolutely committed to securing the future of our business for the benefit of our colleagues, our customers and our communities - whatever external challenges we may face."
