Well, I don't share his summary of the position. In particular, the very clear advice I've had is that this service is not available consistently in England. I'm not aware of the position in Scotland, but this is not available in every part of the NHS in England, and we don't yet have a clinical consensus. There are a number of advocates who do say that it is a game changer; that is not yet the clinical consensus view. That can either come from NICE guidance or it could come from the Welsh urology board, who are now examining the issue. If the Welsh urology board give us advice, that would then draw on the basis for a clinical consensus and we could have a service that is then planned and delivered across the country, as opposed to the current pathfinders in two of the health boards, which, of course, are adding to our evidence base. So, I want to see the issue resolved so we do understand if there is clinical consensus. Then, as I've said on a regular number of occasions, if the evidence and the advice changes, I would expect our healthcare system to act on the very best available evidence and advice to us.
