Ministers regularly state that there will be £10bn extra in funding for the NHS by 2020-21.
The £10bn figure is calculated in real terms once inflation has been taken into account and includes £2bn which was announced in the last Parliament.
The health committee says that while the figure is not incorrect, it is misleading because it can only be reached by adding an extra year to the spending review period, changing the date from which the real terms increased is calculated and disregarding the total health budget.
The committee says a substantial part of the extra funding for the NHS comes from cuts to other areas, such as public health.
Dr Wollaston, Tory MP for Totnes, told BBC Radio Four’s Today programme that the head of the NHS had been “very clear” about what the organisation needed, but the government was not delivering.
