As I said in my first answer to Mark Isherwood, there are pilots running in Wales. If there is a new clinical consensus, underpinned by evidence, in Wales, we can make a system-wide shift. That is where we are. There are pilots in the three health boards that you mention. The evidence base for that is gathering and growing, and we will then be able to make a choice on the basis of the evidence and on the basis of the very best clinical advice. Until then, I don't think any health Minister would say that they wish to direct the health service to offer a service that is not underpinned by the very best available clinical evidence and advice.
