Because there's a big budget anyway, so any big cash increase is relative to the total budget.
And there's inflation as well.
It's less than the amount invested by Labour between 2004 and 2009. when you look at percentage increases and inflation.

"The Prime Minister claimed many times throughout the campaign that the NHS is receiving £34 billion. He’s described this as the biggest spending increase in modern memory, or a record sum or the biggest boost for a generation.
It’s correct that £34 billion has been announced for the NHS (but only if you don’t account for inflation) between 2018/19 and 2023/24.
Whether or not you think this is the biggest increase in living memory really depends on how good your memory is, and it’s certainly not the biggest spending increase ever over five years. If we account for inflation—the meaningful way to look at spending over time—the last time there was a larger spending increase on health in England was between 2004/05 and 2009/10."
Tory lies again - and one he repeatedly makes.
