Around 4,500 staff at Tesco are set to lose their jobs in the latest round of redundancies at the UK's biggest supermarket, the company has announced.

The majority of workers will go from Tesco's Metro stores, with other positions going at some Express and larger stores,Tesco said.

Bosses want to overhaul the Metro stores, which are bigger than Express stores but smaller than larger supermarkets, saying that shoppers tend to use them for top-up shops, rather than buying bigger baskets.

In 134 Tesco Express stores - out of 1,750 - there will also be a reduction in opening hours due to low footfall.

The company said in a statement: "The Metro format was originally designed for larger, weekly shops, but today nearly 70% of customers use them as convenience stores, buying food for that day."

The changes to stores will include fewer products in the back of the store, with more moving straight to the shop floor when they are delivered.

Staff will also be expected to be more flexible, working across different departments and adding more focus on keeping stock levels high during busy lunchtime rushes, among other tasks.

There will also be a "leaner management structure" and workers will be given headsets to communicate more easily throughout the stores, the company added.
