Thank you for raising both of those issues. On the matter of face coverings in schools in Wales, I will ask the Minister for Education to review your comments this afternoon and to write you with the latest position, especially in respect, as you say, of the fact that lateral flow tests are now available. On the matter of resourcing for NRW to undertake its enforcement work, I will ask you to write to the Minister with some more detail about the specific smoke problem that you've described this afternoon in order for her to have that fuller picture in order to respond to you.
