Thank you to Laura Anne Jones for raising that important issue. The Minister for Education does have questions in the Chamber tomorrow, so that might be an opportunity to explore some of this in more detail, but, alongside that, I will ask her to write to you with some further information about the plan for testing children in school, and also the advice that is being provided to schools specifically in terms of sending children home for self-isolation and so forth, and also the kind of thinking that's going on in terms of the approach to Christmas and ensuring that we keep children and their families as safe as we possibly can.
