This has been explained at length.I think BoJo is about to sail into very troubled waters, with a lot of it coming from his own back benches.
There is a debate scheduled for next Monday.
I think BoJo is going to be on the end of a lot of incisive questioning - a lot of it from his own back benches. And some of the criticisms will be difficult to defend against - such as why he is gradually edging back towards a more stringent lockdown for all ages when the risk of death is far, far higher in the over 65's and minimal below that.
Until now, BoJo has put his policies though without it being subject to scrutiny by parliament. I don't think he's going to be able to renew his powers 'as-is'. There is a move afoot among Tory MP's - who will align with the opposition - to force him to renew the bill on a monthly basis.
Which will both force him to explain a longer term strategy and mean that every decision of his will be subject to regular parliamentary scrutiny.
This is a self-inflicted wound by BoJo.
Children are at minimal risk but can then infect their elder relatives.
Boris has actually been consistent on this since he first wanted to reopen the schools.
