Liberal Democrat health minister Norman Lamb is calling on the Conservatives and Labour to match his commitment to invest an extra £8bn a year in the NHS by 2020.
Norman has written to Jeremy Hunt and Andy Burnham calling on them to commit to meet the financial needs of the NHS as set out by Simon Stevens, the Chief Executive of NHS England in his Five Year Forward View.
The Liberal Democrats are the first party to present a plan that commits to investing £8bn a year in the NHS by 2020.
In his letters, Norman Lamb invites the Conservative health secretary Jeremy Hunt and Labour's shadow health secretary Andy Burnham to take part in a non-partisan review of health and care services, as well as to meet the funding commitment.
Norman asks for political differences to be put aside in the interests of sustaining a "vital national institution."
He also says that mental health services and preventing ill health should be made priorities for the investment.
Liberal Democrats in government have successfully pushed for extra funding for the NHS with Autumn Statement confirming an extra £2bn a year beginning in April.
