The chairman of Tesco has said there is an “overwhelming case” for a windfall tax on energy companies to help those suffering the most from the cost of living crisis, as some customers have started rationing the amount of food they buy at the supermarket.

John Allan said the country was facing “real food poverty for the first time in a generation,” and that people were finding it even harder to mitigate soaring energy costs.
