The hon. Member goes slightly further than I did in saying that ventilation should be rolled out immediately across all schools. Of course, that would have significant financial implications. It would also, of
course, be very good for British business. We are saying that, as has been clear throughout the pandemic, better ventilation in public buildings should be a significant part of building regulations in general. What I seek from the Minister is a sense that any of that, never mind all of it, has been done at all.
