For a start, I would have taken notice and acted on the findings of Exercise Cygnus .
I would have not permitted the Cheltenham Festival to have gone ahead, as well as a number of other large gatherings around that time.
I would not have been so stupid as to have refused to take advantage of the pan EU procurement scheme for ventilators, PPE etc.
I would have taken up ( or at least investigated ) numerous offers from small/ medium companies who were offering to supply essentials - and still are.
As I said, that's just for starters !
