I thank my right hon. Friend for his question. The National Audit Office has looked into that in detail. I do not have a figure to hand, but he is right. All these measures have an important role in health prevention, which plays a hugely important role in the cost. NHS spending was just over 40% of the resource spending of all Whitehall Departments. When we think of it like that, there is a clear incentive for Government to work together to tackle things such as air pollution to try and reduce health problems and health inequalities, which will also have an impact on an already massively overstretched NHS budget.
