Norfolk could be set to lose some of its supermarkets as Sainsbury's announced the closure of up to 125 of its sites.

The chain is set to close a number of food shops, as well as Argos branches - which the group also owns.

The chain has not revealed where the stores set to shut will be - but has confirmed that a maximum of 15 main supermarkets will close and 40 convenience stores.

However this is being counteracted by the opening of 10 new supermarkets and 110 new Sainsbury's Local convenience stores.

An additional 80 Argos branches are set to be opened within Sainsbury's outlets.

"We expect the closures to deliver an ongoing net operating profit benefit of £20 million per year," Sainsbury's said in an update to shareholders.

Sainsbury's also confirmed that no jobs are set to be lost as a result of the Argos store closures.
