The FTSE 100-listed company said that the decline in sales was an improvement from the previous quarter but “the industry has remained very competitive”.
Morrisons has struggled to maintain its place in the market without an online business and said today that it is still in negotiations with online grocer Ocado over a possible partnership.
Full year expectations remain unchanged.
“We have made a solid start to the year, with our sales performance improving since the last quarter,” said chief executive Dalton Philips.
“Our promotions have been more innovative and we are explaining Morrisons’ points of difference more effectively. These efforts were further reinforced by the horsemeat scandal which helped drive increasing customer recognition of Morrisons unique supply chain and approach to meat sourcing.”
