The differences of opinion just go to show how complicated an issue a health system is, and why politicians should not be allowed to meddle with it on such a large scale so frequently. The current proposals for privatisation are an extension, I'd agree, of what has gone on before (not just the Tories) - but they go much further and drop us into competitive markets which simply do not work in the interest of the population when it comes to health.
Yes, markets work very well in many many areas of life, but not health (because that's what we want, isn't it? not healthcare i.e. not lots of trips to dr, hospital, tests, surgery, drugs, etc). Markets can work in some parts of healthcare - when you don't need help urgently, when it's easy to compare different options because they're not complicated, when you can trust your adviser is not advising you to line their own pockets, when you are not frightened. Complications arising from too much healthcare are of course much more common where the providers make a profit (and look what has happened here in dentistry.)
Competitive markets will make healthcare even more expensive (hence more expensive in france, germany etc. as mentioned earlier) and need a lot more regulation to be safe (see what has happened with breast implants recently). Either tax payers will have to pay more to cover the profits of companies (if the 'NHS' remains free at the point of use) and costs of more contracts, and costs of more regulation or pay for less stuff (leading to more private health insurance and stark problems of the US system).
No the NHS isn't perfect (and the current proposals have exposed the potential for conflicts of interests in GPs who are of course not NHS workers), but it would be in a lot better state if politicians would leave it alone for a while. Even so, satistfaction ratings with the NHS are at an all time high - and then the current government proposes the biggest change ever while making the biggest cuts ever (thanks, bankers). There's room for improvement, but leaving it to the mercy of markets isn't the solution.
Oh, the current bill also removes the responsibility of the Secretary of State to provide a health service. It's bad enough now trying to hold the government (any government) to account for what they do to the health service. There's no chance if this bill goes ahead.
