I think the hon. Lady said “should, or indeed must”. We are certainly not compelling people to wear face coverings. But plainly they can be of benefit to others primarily because they stop the aerosol transmission of droplets, which may contain infection. We can help each other, as I said in my introductory remarks, if we wear cloth face coverings in confined spaces such as on public transport, where we will come across people with whom we are not normally in contact, or in shops. We think that it is advisable to wear such cloth face coverings.
