Sue Davies, Which? Head of Food Policy and Consumer Rights, said: "With so many families already struggling to make ends meet during an unrelenting cost of living crisis, it's hugely concerning that food prices could rise significantly over the summer. "Recent Which? research found that the price of hundreds of everyday groceries had soared by over 20 per cent over the last two years and that own-brand budget groceries have become less available. "Which? is calling for supermarkets and manufacturers to be more up-front about costs and provide really clear unit pricing so people can easily compare items. Budget ranges should also be more widely available across stores so consumers do not have to pay over the odds for everyday essentials." ENDS
