The prime minister has prepared the ground for tax increases to fund the NHS.

Speaking to the BBC, Tony Blair, who ruled out a designated health tax, said that he wanted sustained investment funded "out of general taxation".

He said: "If we want sustained investment in the National Health Service over a period of time, we are going to have to pay for it and I believe we will find that money.

"In my view a fairer and better system is through general taxation. I hope that in the coming months that we will be able to show that we are able to make that commitment."

His comments are being seen as a clear hint that taxes will rise in the April budget.

During the interview the prime minister ruled out free long term care for the elderly.
