No 10 said that face coverings would be mandatory for all customers in enclosed public spaces including supermarkets, indoor shopping centres, transport hubs, banks and post offices.

The rules state they must also be worn when buying takeaway food and drink, although can be removed by customers in seating areas.

As has been the case with existing mandatory rules, like on London’s Underground network, face coverings will not be necessary for children under the age of 11 or those with disabilities or certain health conditions.
