Cameron vow to ring fence NHS spending for another five years

Funding for the NHS in England will be protected from cuts for five years if the Conservatives win next year's general election, David Cameron is to say.

He will promise real terms increases in health spending in his main speech to the Conservative conference.

It is a repeat of the policy on which he fought the 2010 general election.
