Waitrose has unveiled price cuts on more than 200 products across its range as part of an investment to retain customers at a time of persistently high inflation.

The supermarket, which is the food arm of employee-owned John Lewis Partnership, said products such as butter, tomato ketchup and golden caster sugar, as well as salads and ice cream, would all have their prices lowered.

More than half of the 200 products would now be at least 10% cheaper, it added.

“We’ll still react to any drops in food inflation and pass on savings to our customers as soon as the prices we pay begin to fall,” said Charlotte Di Cello, Waitrose’s commercial director, as the retailer unveiled the £100m investment in price.

Food inflation in the UK remains stubbornly high, up more than 19% year on year, according to the latest Kantar figures.

It has also outpaced broader inflation and strained household budgets already stretched by rising prices elsewhere.

As a result of this, grocers who have been unable to keep prices on staple products low have suffered steep drop-offs in trading.

Despite investing huge amounts in food prices over the period, the likes of Tesco and Sainsbury’s have been unable to keep a lid on the growth of Aldi and Lidl in terms of market share.
