Asda has reported falling sales for an 11th quarter in a row as it continues to lose ground to its rivals.
The UK's third biggest supermarket revealed sales in the three months to end of March fell 2.8% on a like-for-like basis.
It was a slight improvement on the previous quarter, but analysts warned more work was needed.
By contrast, Asda's parent company, Walmart, revealed a 1.4% rise in like-for-like sales in its native US market.
No complacency
Asda's latest fall was nowhere near as bad as the 7.5% drop in quarterly sales that it reported in August last year, and was slightly better than the 2.9% decline seen in the final three months of 2016.
But chief executive Sean Clarke admitted more needed to be done to recover.
He said: "We're pleased that the momentum of Q4 has continued into the New Year with a third consecutive quarter of improvement.
"Despite this progress we are in no way complacent and there is still much for us to do."
