Doctors should NOT be allowed to administer or prescribe any substance which is NOT normally potable.

I really don't see how privatization in-and-of-itself is a threat to the NHS though. Have you ever seen how healthcare works in countries like France, Germany, Netherlands or even Japan? These countries follow a more Bismarckian healthcare system than a top-down government-run model like our NHS. In essence, it follows a hybrid model where every resident is obliged to be covered under a statutory health insurance which is funded through taxes and social security contributions and this could be topped-up with private insurance. These come from a selection of not-for-profit private health insurance companies where people can choose their healthcare plan according to their needs. In France, the government reimburses 70% of your healthcare costs. This percentage is even higher depending your employment status, financial situation or the severity of the illness where it can be as high as 100%. For people who are more financially affluent, they can choose to increase this reimbursement to 100% through their private health insurance known as "mutuelles". The hybrid system has time-and-time again proved to outperform our socialised model in terms of the quality of care, waiting lists and adoption of technology. Our NHS is too inefficient due to high bureaucracy and governments not wanting to take risks (i.e. innovate) with public money due to high political costs of failed innovation. The fact that our healthcare is free regardless of the person's economic background and the nature of the appointments is exacerbating our waiting list crisis.

But the UK is not attempting to follow the European models.
