I would support a very strict 2-3 week national lockdown, including schools and a local (5 miles) and international travel ban with the exception of keyworkers, urgent health appointments and so on; no private jets coming in and out either this time. A travel ban is essential to reduce viral spread from high risk areas and to prevent a repeat of the shameful scenes of crowded beauty spots, National Parks and beaches. I think it should start with urgency on Friday, (next Friday at the latest), timed to extend half term, and expect to have to repeat it several times before next summer. I think it is the only way to save lives, protect the NHS and prevent a many months' long lockdown which would be much more detrimental to the economy and mental health.
Boris is getting things wrong (again). It is almost as if he thinks that the vast majority of people who will die are expendable cannon fodder.
I am a parent of school age DCs, one in the most important exam years, but there is little point to a 'circuit breaker' unless we include schools. Year group bubbles can be huge, siblings are in other bubbles, many travel crowded together on buses, and then return home to families and the community including the more vulnerable. We have been shielding a family member since March without any help at all - Boris says this is not necessary but all the best advice we have received says otherwise.
Extremely difficult times, in different ways, for many people. I think we have to look after each other and ourselves as best we can because I see no evidence that a careful, skilled hand is on the tiller guiding us through this terrible hooley of a returning storm.
