Co-op’s update came as Office for National Statistics figures showed a surge in food sales despite the worst fall in retail sales since records began, in 1996, in March. Revenues fell 5.1% including fuel, and 3.7% excluding it. Clothing sales were worst hit, down 35%, as non-food slumped 19% overall despite a record 22.3% surge in online sales. But food revenues rose 10.4% amid a wave of stockpiling.
