Thank you. I just wanted to say briefly, because I didn't have time to come in—I'll just declare an interest, my father has glaucoma—what wasn't mentioned in this debate was the way that some of the systems behind sight loss treatments are being privatised. My father has had a call from a private company in Preston to change his appointment from the Prince Charles Hospital in Merthyr to the Royal Glamorgan, and hasn't had an appointment in many, many months. It's not only him; since he's done some public work on this, people are being referred to services outside of their areas, because, simply, those particular appointments are not—specialists are not being held in those areas, so they can't be seen locally. What are you doing to challenge some of the operations behind this issue, if you have this new vision? Why are private companies involved in this process?
