I don’t think it is required. A national lockdown before Xmas will cause panic buying again... you won’t be able to get a big tub of Quality Street for love or money..
The problem being people don’t adhere to the current level of restrictions, so going back a step won’t be listened to.
Schools are not the problem, if they can get the kids to wear masks when needed. Scotland govt failed in that respect after saying masks should be worn 2 weeks after they went back.
The biggest problem is opening the pubs. If they couldn’t get customers to behave properly before, how can they get them to now?
North Northumberland is now in a local lockdown, which means my local supermarket is back to marshalling queuing customers outside, counting them in and out....
But the pubs now have a curfew! They must close 1 hour sooner than they have been. What a lot of difference that’s going to make!
