Two points: the first is that we have already restarted screening services, as I've previously reported back to Members. The second is: you may not have picked this up, but Tom Crosby has confirmed that there has been agreement within NHS Wales to roll out a national programme of diagnostic centres, following the trials that have been undertaken in Neath Port Talbot and, actually, at the Royal Glamorgan, at the diagnostic hub there as well. So, I will be providing proper detail to Members on the detail of that roll-out programme, but it's a good opportunity to say that the trial that we've been running in Wales has been successful, and we expect that to take place in a national roll-out. So, I think perhaps we're already half a step ahead of the question that's been asked today.
