My right hon. Friend has said time and again this morning that if people do not have symptoms, they should not get tested, because the antigen test does not work if someone does not have symptoms. Patrick McLoughlin—a good friend of ours, now in the House of Lords—always used to say to me, “If you want to keep a secret, say it in the Chamber of the House of Commons.” How can we get this message across with some snappy title, rather like the rule of six? It is very straightforward. How can we get across the message that if people do not have symptoms, it is pointless and a waste to go and get tested?
