Johnson should be saying:
'The situation is serious; we are closing all restaurants, shops, hotels and leisure facilities as this seems to be working in stemming the spread in Europe. Food shops and pharmacies will remain open. All other businesses must close unless they are part of the food chain (dairies, logistics etc). Everyone except key workers must stay at home and can only go out to collect food (which will be rationed if you don't behave sensibly) and medicines.'
I don't want to hear:
'Wiff-waff, piffle-piffle... 20,000 new ventilators built out of tractor parts; all patriotic nurses under 80 to report for duty; it will be all over in 12 weeks if we just think positively, and to help us do this, I'm letting my friend and party donor Mr Martin keep his Wetherspoon beer halls open etc....'
He might of course try to deflect the whole crisis:
'In times like this, I'm conscious of the need for us all to pull together, so I'm setting up a government of national unity to take over. Naturally, I'll sit at the head, but just as when I was Mayor of London I'll take all of the credit when things go well - and put the blame on someone else when they go wrong.'
