Prime Minister David Cameron is to renew his vow to boost NHS funding and create a "seven-day" health service in his first major post-election speech.
He will commit to a pre-election pledge to increase budgets by at least £8Bn a year by 2020, during his speech at a GP surgery in the West Midlands.Outlining the government plans, he will say the NHS is "safe in our hands".
But doctors' representatives said without detail the announcement was "empty headline-grabbing".
The British Medical Association said the government was yet to explain how it would deliver additional care at a time of "chronic" doctor shortages.
Before the election, the Conservatives gave their backing to a plan by NHS England chief executive Simon Stevens to fill a funding gap estimated at £30bn a year by 2020.
This aims to make £22bn in efficiency savings, with the rest coming from taxpayers.
Conservative-led Local Government Association warns that fresh round of cuts would devastate local services and communities.
Tory council leaders across England and Wales have presented a united front with Labour and Lib Dem-run local authorities as they warn the chancellor, George Osborne, that another round of funding cuts would devastate local services and harm the most vulnerable in society.
In a letter to the Observer, council bosses representing every type of local authority in England and Wales, as part of the Tory-controlled Local Government Association (LGA), say they have already had to impose cuts of 40% since 2010 and cannot find more savings without serious consequences for community life and social care, and knock-on effects for the NHS.
