Asda has slashed the price of its top-selling items to just 50p.

For this weekend only, products including bananas, sausages, mince, bread, eggs and potatoes, have been priced at 50p.

It means customers will save 78p on a kilo of loose new potatoes, 35p on Asda Smart Price butter and £1.18 on green seedless grapes.

Tesco will respond by reducing the price of 3,000 items from Monday, according to The Times.
