I think it's a fair question. What I've done is I've asked our technical advisory group to look again at the current evidence, not just on the new variant, but the evidence of COVID and education, and my understanding has been that teachers are not high-risk professionals. Other education staff are not high-risk professions, and that's good news. And it's credit to those teachers, and other leaders who organise those work places for their staff, that we don't see large amounts of coronavirus spreading through our schools, and we don't see evidence of pupil/learner transmission to staff members, and that's a good thing. It shows that people are respecting social distancing where it's possible.

Now, that then means that we need to understand this, because the same control measures are the ones that will be effective—that's good ventilation, as I have mentioned in my statement, and your colleague, Rhun ap Iorwerth, is keen on as well; it's also social distancing; it's also about having consistent cohorts of people—for the new variant, as for others. But the stringency will be even more important because the new variant is more transmissible, and that is the main change in the operation of the new variant. Now, we're of course looking to see if there is any other change within it, but that was the very clear advice that I had when I spoke to scientific advisers and the chief medical officer just yesterday. And the chief medical officer was clear with me that there was no reason, no evidence at that point in time, to change our approach to prioritising education and the balance of harms that we always have to run through. Because, as I'm sure the Member understands, there is real harm done to children and young people if we end up closing schools unnecessarily, and that harm is something we should not walk into lightly. We would need to have evidence that it is not safe to return to school, because actually the current evidence is that, with the conditions that we are planning for, we should be able to return to school safely. And there's extra reassurance for learners and staff and concerned parents, because we'll have serial testing in our secondary schools as well. That will mean that people don't need to isolate unnecessarily. It also means we should identify more asymptomatic cases as well. So, I actually think that is additional reassurance, compared to where schools were operating at the start of December, for example, when we were seeing a rapid growth in coronavirus across large parts of Wales. 

But, of course, I'll continue to talk with the education Minister, as I indicated in response to Lynne Neagle. And I know that she will continue to have dialogue with trade unions and, indeed, the Welsh Local Government Association, because all of us, surely, want to see children's education and learning protected, not just the value of it as to the straight education provided, but the wider learning and protection that a school environment provides. So, I am very keen that we maintain that. It's a stated priority of this Government, and it would take something extraordinary for us to say that we did not want schools to go ahead with the already agreed plans that are in place between the education Minister, the WLGA and, indeed, our trade unions.
