courtesy of the independent, the poll figures are from poliics home.
A total of 59 per cent of voters agree that 'deep down, the Conservatives want to fully privatise the NHS', while 45 per cent think any reforms to the Health Service made by the Tories are designed to 'help business, not patients'.
The Prime Minister's five pledges are designed to assuage these fears, but leave the door open to changes.
He vowed that waiting times would not go out of control - a tacit admission that they are rising and will continue to do so.
He added that there is too much difference in quality of care in different regions.
Critics will also point out that the notion of a 'national' Health Service is likely to be watered down when GP commissioning gets under way, as it is likely to lead to a postcode lottery with different health outcomes in different parts of the country.
Mr Cameron's speech is part of a month-long PR campaign designed to salvage reforms drawn up by the embattled Health Secretary Andrew Lansley, which have faced massive opposition from the general public, health professionals and Liberal Democrat MPs.
Today, the Prime Minister said his campaign is beginning to bear fruit.
'A whole range of people are changing their view,' he will say.
'Before the pause, many were claiming the NHS is fine, and telling us not to touch it. Now, whatever their views about how to do it, most agree change is needed.
'What's more, a significant number are now more clearly on board with the thrust of what we are proposing.'
The Prime Minister said that GPs representing 1,100 practices across England have expressed support 'for the basis of our plans', along with the Association of Surgeons of Great Britain and Ireland and the Royal College of Surgeons.
He added that patients' groups such as Saga and Age UK have also 'backed key parts of our plans'.
The Prime Minister is due to unveil details of the changes to the Coalition's health plans next week after halting the passage of legislation to consult doctors.
