I think it is going to be a disaster and is going to take us a considerable distance down the road of privatisation of the health service. I've yet to meet anyone in the medical profession who thinks it will be a good thing (I know nurses, doctors, MWs, HVs....). The professional bodies and even the Health Select Committee are all warning against it. The GPs don't even want it.
If there is to be reform I'd like to see more centralisation rather than devolution as it would contribute to ending the postcode lottery in healthcare. This is absolutely going ot make it worse. It already is.
