On a video on Twitter, Johnson said: "I want to say a special word about testing because it is so important, and as I've said for weeks and weeks, this is the way through."
The UK had stopped the mass testing of people with COVID-19 symptoms three weeks before, advising them to self-isolate instead.
On March 12, England’s Chief Medical Officer Chris Whitty said that it was “no longer needed for us to identify every case” and that the country would move to mainly testing those in hospitals with symptoms.
This is one of many unreliable and confused statements by Johnson about the virus. His words were not matched by his actions.
