Supermarket group Morrisons says its retail sales performance was "again robust".
It says like-for-like sales, which strip out new store openings, were positive in the first quarter for the fourth consecutive year "despite political and economic uncertainty continuing to impact consumer confidence".
Sales during Easter period were up 1.7% on last year and 3.4% on a two-year basis.
For the 13 weeks to 5 May, group like-for-like sales excluding fuel were up 2.3% and including fuel were up 2.7%.
It says it expects "the market to remain competitive and challenging" and in the second quarter will annualise last year's favourable summer weather and the World Cup.
