Sainsbury

The government has written to Sainsbury's and Morrisons asking them to stop "advertising and promoting" heated tobacco products, which it says is against the law.

In response to the letter, Sainsbury's said it was in "close contact with the government", while Morrisons said it would reply "in due course".

The election comes after Lord Sainsbury of Turville announced last year he intended to step down after more than a decade in the role.

It follows a similar move by Sainsbury's, which has rolled out AI recognition technology at self-service checkouts at some of its stores.

"We regularly review the security measures in our stores and our decisions to implement them are based on a range of factors, including offering our customers a smooth checkout experience," said a Sainsbury's spokesperson.
