Just cause the dollar amount is increasing doesn't mean it isn't being defunded. You have to account for inflation, population size, and population age distribution.
Ay, there's the rub.
Want a comparison? France's healthcare spending increased 0.3% yearly in the same timeframe. The UK is outpacing France's spending increases by 2,066%.
The spending argument is made from political propaganda, not from fact.
Could you provide a source for that? Such an increase would imply a doubling of the budget over that time period. I can't find anything that suggests the NHS budget has doubled since 2010.
From what I can gather, the NHS spending adjusted for inflation increased modestly over the time period.
Taking into account the fact that costs in the healthcare sector have increased more than CPI globally, that increase could well correspond to a decrease in purchasing power.
That doesn't yet take into account the UK specific issues around Brexit.
The spending argument is nuanced and complex. Declaring that it's "not from fact" just reveals your partisan leanings.

And yet, both of these trends can continue for quite some time, and one trend can outweigh the other for quite some time.
