First Minister, yes, that's very welcome news about the vaccine, but, as you say, people need to continue to act sensibly, and obviously safety comes first. But I have a question for you that I probably did not make as clear as I should have done last week, and that's on football. So, it affects clubs that have come to me from Caerphilly, South Wales East and, of course, it affects the whole of Wales. On the 30-outside post-firebreak rule, there are, obviously—I'm a football fan, so I know—11 a side in a football match. But in the rule of 30, you have 11 a side if football teams want to play each other, one sub each, one manager and one coach, and then there's enough room for a ref and a first aider. There is no room for linesmen and, obviously, there's no room for any more subs. So, I was just wondering, First Minister, as that's okay for training, and it's okay, sort of, for friendlies, but a bit of a strain with just having one sub, if our clubs are to start their season—they've started it in England, they're just on pause—if they're going to start their seasons here in Wales, how do you propose they do that if the rule of 30 obviously only means that they can have those people on the pitch, but they can't have the linesmen and everything like that? Is there going to be some concession to ensure that they can start their season? I just wonder if you could explain it a bit more for me, please, First Minister, or look into it. Thank you.
