At least in some areas.
It seems madness to me, after having to admit things are out of control in Schools (in London and SE, if not elsewhere) to positively encourage multi generational gatherings over Christmas.
I also wonder how many people plan to have their 3 household bubble and how many will decided it's too big a risk. My parents have said they're having Christmas on their own and whilst elderly, they have no additional risk factors and are not normally anxious.
Schools here are already gearing up for carnage in the New Year. We are currently debating going back on a remote timetable.
