From today in Parliament:
"I increasingly think it is disgraceful that the Labour Opposition continue to blame NHS Test and Trace for the resurgence of the disease. There is a complete hiatus in their logic. They are talking absolute nonsense. Testing and tracing has very little or nothing to do with the spread or the transmission of the disease. The spread and the transmission of the disease is caused by contact between human beings and all the things that we are trying to minimise. Of course NHS Test and Trace is vital, but the way to fix the problem now is for the whole country to follow this package of guidance, drive the R down and allow both education and the economy to continue. There is a complete flaw in the Opposition’s logic"
Of course being able to test and trace people will affect the spread of the disease. It's what has been said from the start.
But Boris won't be having it, will he....
