“Whilst we will do all we can to strongly encourage customers to wear a face-covering inside our stores, it is the responsibility of the relevant authorities to police the new rules.”
The supermarket chain also said they “encourage” shoppers to use face coverings.
Asda said: “We are strongly encouraging all customers to wear a face covering when they visit our stores.
“We also have signs at the entrance to the store and on the shelf edges to encourage customers to wear a face covering and are using Asda FM (our in-store radio) to further remind customers.
“While we will do all we can to strongly encourage customers to respect the new guidelines, the responsibility for policing and enforcing them does lie with the relevant authorities.”
