Sainsbury’s has confirmed it will post trained security guards at shop entrances to 'challenge' any customers not wearing a mask or shopping in groups.

Chief executive Simon Roberts said: “I’ve spent a lot of time in our stores reviewing the latest situation over the last few days and on behalf of all my colleagues, I am asking our customers to help us keep everyone safe.

“The vast majority of customers are shopping safely, but I have also seen some customers trying to shop without a mask and shopping in larger family groups.

“Please help us to keep all our colleagues and customers safe by always wearing a mask and by shopping alone. Everyone’s care and consideration matters now more than ever.”

There are more than 10 Sainsbury's supermarkets and Sainsbury's Local stores in Oxfordshire.

It comes after Morrisons announced yesterday that it would ban customers who refuse to wear face coverings unless they are medically exempt.

There had been concerns raised by shoppers that supermarkets are not being tough enough on social distancing measures.
