I'm grateful to Mark Isherwood for raising the important issue of the experience of blind and partially sighted people in supermarkets during the current restrictions. I know that it does make situations particularly difficult for them, especially when people don't always understand that blind and partially sighted people might find it more difficult to maintain that social distance, and so forth. I'm aware myself of the RNIB work, but I will ensure that the health Minister—although I'm sure he's already familiar with it—does review that, with a view to exploring what more we can say to ensure that people aren't disadvantaged and that awareness is heightened as much as possible.
