My Lords, like the noble Baroness, Lady Noakes, I like to spend an evening at the Royal Opera House. In fact, I have been a couple of times in the past three weeks and noticed from where I was sitting that enormous numbers of people were wearing masks—including one John Major, sitting just in front of me. I cannot see that there is any problem with sitting in the Royal Opera House and wearing a mask. In the area where I sat, there was very high compliance. It is not even just that there have been these announcements. The fact is that there was an announcement from Antonio Pappano every evening before the performance, encouraging people to wear masks. My own view is that it would have been much better if we had never stopped people wearing masks. We would not then have to start every time from a lower base to encourage people to take it up. The noble Lord, Lord Robathan, said that it may have stopped transmission on some occasions. Is that not good? That is what we want to happen.
My second point is about schools. The fact is that schools are not generally well-ventilated buildings. My daughter is a year 4 primary schoolteacher and, for the whole of last year, she had to teach with the windows open. This year, they have come back and again had to do so. It is not easy for a child to learn in a very cold classroom where they have to wear their coats, hats and gloves. It would be so much better if
we had managed to get in a programme to bring in ventilation or some kind of air filtration scheme. Although there was a big concern about whether young people would be oppositional to the idea of wearing masks, people I know who are teachers—I do know a great many of them—have found that when you have the discussion with young people, they absolutely understand why it is important to wear masks: it is about protecting themselves, each other and their grandparents, who they may see out of school.
While a great number of things have been done too slowly, the reinstitution of wearing masks has been done in a speedy way. I hope it will continue beyond 20 December.
