Thank you. My understanding is English trusts do not treat Welsh residents differently, in the way that you've suggested, and I think the best way forward, the best course of action, probably would be to ask the Minister for Health and Social Services to get her officials to monitor that. Certainly, her officials would monitor any commissioning arrangements that they had with English hospitals. I'm not sure if ambulance waiting times is something that would be considered as part of those commissioning arrangements, but, certainly, I think it would be good for the Minister to ask her officials to look into this and write to you.
