Well, the guidance and decision making of the Government that you referred to, of course, relies on the advice of the Chief Medical Officer for Wales, Dr Frank Atherton. He has reviewed the evidence, and the advice that is current in Wales comes from his advice and recommendations to us, and that is that there is limited benefit and that he is not in a position where the evidence is strong enough to recommend that people do wear masks in particular situations outside, of course, front-line care work as part of PPE.

When it comes to what might happen in the future, as I've said and will say on a number of occasions, where the evidence changes, we'll be happy to shift our position. And indeed, the chief medical officer will, of course, continue to review the evidence. In each of these—as we've seen on testing policy—it's possible that that evidence changes fairly rapidly.

We made three different choices on policy over a six-week period on care home testing because the evidence base had changed at a really rapid pace. And that's pretty disconcerting for the public, I know, but it's pretty disconcerting for decision makers as well. But if we're not prepared to be agile in decision making and being prepared to reconsider where we are as that evidence base firms up, then we won't be in the right position.

So, it is possible that there will be a change in the future, but the current advice from our chief medical officer is not to do so. But as I say, I wouldn't want to close off the reality that that advice could change and the chief medical officer's advice could change. At which point in time, of course, you would expect Ministers to make a different decision.
