The pilot you refer to in England is a London-only pilot, so it's not a national pilot that takes in the whole of England in any event. We have pilots that are being run here in Wales in a variety of health boards. As I say, we will continue to provide a service that is in line with NICE guidance. The NICE guidance is due to be updated in April 2019. If we have the Welsh urology board—again, our clinicians here in Wales—if they reach a clinical consensus in advance of that, we can make different choices right across the service, but at this point, the provision is evidence based. Actually, there is a high satisfaction rate from prostate cancer patients here in Wales. I'm satisfied that health boards are doing what they should do, but, of course, we will always have more to learn from pilots in every part of the country, just as, indeed, pilots in north Wales will have much to teach the rest of the country in a variety of areas; for example, in a different area of the advanced paramedic trial in north Wales, where there'll be learning for the rest of the country to learn from there. It is entirely normal to have pilots to take learning from and then improve the whole service—that is exactly what we are doing with prostate cancer as well.
