Sainsbury's unveils £15 million of price cuts across cupboard essentials including rice and pasta

The company added that, from Monday, all Sainsbury’s “happier and healthier” whole chicken breast fillets will be price-matched to Aldi for the first time.

Rhian Bartlett, food commercial director at Sainsbury’s, said: “As the cost-of-living challenges continue, we remain relentlessly focused on lowering prices on the essential products that make the biggest difference to customers.

“These latest price cuts will help reassure customers that we will continue to pass on savings as soon as we see the wholesale price of food fall.”

The move comes as supermarkets are under increasing pressure to hand down savings they are seeing on wholesale items to consumers, who have faced punishing food price inflation in recent months.

The Bank of England suggested last week that some retailers are jacking up prices or failing to pass on lower costs to consumers as a way of increasing their profit margins at a time of stubborn inflation.

Ms Bartlett is among food bosses who will appear in front of the Business and Trade Committee on Tuesday to discuss food price inflation.

Official figures last week showed that food inflation slowed from 19.1 per cent in April to 18.4 per cent in May.
