Well, Llywydd, let me thank John Griffiths for that. And, of course, I agree with him—the fact that we are seeing a reversal of some of the gains that we achieved through the firebreak is concerning, and it is particularly concerning because we know that the higher the incidence of coronavirus in the community, the greater the impact that has on schools, because the more coronavirus there is about, the more likely it is that adults will find themselves infected, and children as well. Now, it is right that local authorities and, indeed, headteachers and governing bodies have some flexibility to be able to respond to local circumstances, but nevertheless it is also a concern that there appears to be a disparity between the way in which some schools organise themselves to prevent the need for whole year groups to be isolated and different levels of risk are acceptable in different schools in Wales. Now, the Welsh Government has done a great deal already to make sure that front-line staff and people who are in charge of schools have access to advice through their local incidence management teams, through Public Health Wales, to try to get a more common understanding of the way in which these risks can be mitigated.

It is possible, Llywydd, that the new lateral flow tests, with their more immediate results, can be deployed in schools in future in another effort to prevent children from having to self-isolate when things could be done to prevent that from happening, for all the reasons that John Griffiths set out, which are the same set of reasons, Llywydd, why the Welsh Government has placed a priority on making sure that our children's education is protected even at this most challenging time.
