My right hon. Friend is absolutely right that we have massively increased testing across the country. We are now prioritising teachers, as he knows. He raises a very important point about school pupils, and an interesting fact is that the rates of infection and transmission among school pupils are much lower than in the rest of the population. But I am not going to hide it from him that the future I see for our country and the way to defeat this virus is massively to expand testing, not just for teachers and not just in schools but throughout the country. That is why I am proud that, in spite of all the difficulties that Keir Starmer and others have legitimately pointed out, NHS Test and Trace is now conducting more tests than any other country in Europe. I think we should be proud of that.
