I agree, Bertram...I did wonder about that too. He must be in a better position than many to hire someone to be with the child if he and his wife were too ill to care for him/her. No Nanny?
The cynic in me tells me there could have been a nanny who cleared off...perhaps?.... :-)
I do know I wouldn't have been putting my parents at risk.
It is a long way to drive when unwell, Zacs.....and expecting to become too unwell to look after a child. Even I know how suddenly this virus can develop from mild symptoms to dangerously ill.
Even Boris was, a few days earlier, advising that leaving children with grandparents was unwise.
Cummings at best made an error of judgement...at worst flouted the regulations which he was partially responsible for. Stupid or arrogant? I'd go with arrogant.
