Health is devolved in the UK. That means there are 4 separate NHS systems - one in England, another in Wales, another in Scotland, and another in Northern Ireland.
I agree that there are severe problems with the Welsh NHS.
Didn't know that but I guess the problems are not limited to Wales. My uncles and cousins are expats in the UK, some in Wales and some in London and they come to Turkey (where we're from) whenever they need the dentist. Whenever they got their teeth done there they had to get it fixed here. What I saw in the hospital is that the medical staff work like salesmen, whereas here there is great respect and love towards doctors and other medical staff, and these in turn work with great devotion. A virtuous circle absent there, unfortunately.
