Making face coverings mandatory in shops in England is being considered by the government to slow the spread of coronavirus, senior sources have said.Speaking in a Facebook Q&A video, Boris Johnson hinted at the change saying: "We are looking at ways of making sure that people really do have face coverings in shops."
Face coverings have been compulsory in shops in Scotland since 10 July.
And speaking on Friday Mr Johnson said "the balance of scientific opinion seems to have shifted more in favour of them than it was, and we're very keen to follow that".
"I don't think we are going to get to a world where we say everyone has to wear face coverings the whole time everywhere," he said, but added "We need to be stricter in insisting that people wear face coverings in confined spaces where they are meeting people they don't usually meet.
