And let's just stop on that for a moment, because when the Prime Minister was answering questions in this House back in March, I think it was, she said the Government is not going to use saliva testing; it's going to use PCR testing. Now, let's just think about this; let's just unpack this for a moment. PCR is the test that is used to detect COVID on the material taken from the person's body. That material can be either phlegm or mucus taken from the nasal cavity, or it can be saliva taken from the person's mouth. Now, to say "We're not going to use saliva testing; we're going to use PCR testing", as the Prime Minister did, shows that, on one of the most critical aspects of the COVID-19 response—using good technology to test rapidly—the Prime Minister had no idea about the first and most basic elements of how this technology works. And, of course, it starts at the top, and the rot goes down, because we've just heard from the Minister that it's not the Government's fault there's not more saliva testing.
