Now, the Government says that the testing's not as accurate—well, that's disputed, for starters. Actually, there is evidence that the tests are just as accurate as the pharyngeal swabs. But even if it's the case—in fact, the Prime Minister admitted this this afternoon in question time—that they're not as accurate, by the repetition of the tests and by virtue of the fact that you are doing it daily, of course you can be more accurate and pick things up more quickly. So we want to see saliva testing, and we're going to continue to push home that point.
