First Minister, following on from John Griffiths's question, I'd like to say that I've also been contacted by a number of worried parents in the Newport constituency area, because, currently, as it stands, there are 1,000 pupils isolating from Caerleon Comprehensive School, my old school. Years 7, 8, 9, 12 and 13 are all off at the moment, which is beyond comprehension really. Obviously, year groups have to stay off if there are enough cases and there's a reason to stay off, but there are schools in other counties with just one case, as is the case in these year groups being off, where they just do the track and trace, like in Monmouthshire County Council, and just keep 15 pupils off rather than whole year groups. Parents are obviously very concerned at this, because obviously it affects their jobs, it affects the children's well-being, mental health, and their education, obviously. So, I'd be really appreciative if you could do all you can and maybe firm up the Government guidelines to schools because at the moment, as you said, there is a massive postcode lottery in education right now happening in Wales. And also, whilst you're at it, if you could also—. You've said to schools recently, about wearing masks, 'That you can wear them if you want to.' Maybe Government guidelines should be stronger so that, in everything, there's consistency right across the board in Wales in our schools; it's very confusing for them. Thank you.
