CONSUMERS have seen the price of hundreds of popular grocery items rise by more than a fifth over the last two years, a Which? study has found.

The watchdog also found the rise coincided with a drop in supermarket discounts and budget ranges as the cost-of-living crisis bites.

Items included Kellogg’s Crunchy Nut Corn Flakes, which increased by 21.4 per cent at Tesco.
