I think the point in that study and, indeed, of other scientists who have vigorously supported the use of face masks, is, as you change the level of restrictions and you therefore lead to more people being in more contact, having a face covering is an additional measure that can then change the number of cases and, indeed, the number of deaths.

Can I just stay with the care sector? If the COVID crisis has taught us anything it's the value of that sector. Care workers have been at the forefront of the battle against the virus, as we know. Their tireless efforts have been hampered at times by the often disjointed dynamic between our health and care sectors and the fact that they're not fairly rewarded for their work. Isn't this the time, First Minister, as we begin to think about a post-COVID Wales, for a national integrated health and care service free at the point of need that will synchronise our most vital public services and give care workers the pay rise and the pay structure that they deserve by moving them onto NHS pay scales? Nothing is stopping this from happening, from political will. Do you share it?
