I just learnt that our council, currently in tier 2, will move to tier 4 on Boxing Day. Can anyone please explain to me why? Why on Boxing Day and not last week or yesterday? What happens to the virus on that day? Why not move up to tier 3? I'm trying to listen and process all the information we are being bombarded with regarding the virus and the regulations but I'm really flummoxed by this tier 2 - tier 4 jump on a specific date.
