The Office for National Statistics (ONS) has said the cost of some of the cheapest food in supermarkets has risen by nearly two-thirds in the last year, heaping extra pressure on struggling households.

Prices have risen across the board, but the ONS has collected 1.5 million prices over the last year to track changes to the cheapest available items on a supermarket’s website.

It gives a snapshot of the extra costs faced by households who are shopping on a budget.
