Then, of course, as the knowledge progressed, in April, we know from written questions that there were then 15 asymptomatic cases and, in my view, played around with the words "pre-symptomatic" and "asymptomatic". That sort of came to me for a while, which I think just confused everything—that is, "pre-symptomatic" meaning they were on the way to infection; "asymptomatic" meaning never going to get it. Well, that's playing with words. Then, on 9 June, the ministry took up the programme of testing asymptomatic arrivals completely at the border. So I have some angst that, way back then, way back in March—in fact, two days in a row—the Minister stood in this House and said asymptomatic people cannot catch coronavirus. I just don't accept that we didn't know that knowledge there. Does it help us here today? Maybe not, but just to talk to the point where he said we know more now, and so we're better—we actually knew back then.
