All of Britain's major supermarkets are seeking savings, reinvesting them to keep a lid on rising prices.

Asda, Britain's third largest grocer after market leader Tesco and Sainsbury's, said it planned to replace overnight restocking shifts in 184 smaller superstores, with the work instead done earlier in the day.

The working patterns of 4,137 workers would also be impacted. They would retain their hours but not receive a night shift premium.

Asda, owned since 2021 by brothers Mohsin and Zuber Issa and private equity company TDR Capital, also plans a 25% cut in the opening hours of its 23 in-store Post Office branches, impacting 23 Post Office managers and 200 workers.

It also plans to close seven of its 254 in-store pharmacies, affecting 14 pharmacists and 48 workers.
