Fuck it. I'll bite.
We can always start with the NHS funding figures from the 2017 Labour manifesto that the National Audit Office branded "highly misleading". It offered up increasing overall funding to the NHS by £30 million over the course of the parliament (2017-2022) which when you get down to it was less than the fucking Tories spent (even without the covid uplift). Or shall we go to the 2019 Labour manifesto plan for the NHS that was basically exactly the same but with the overall funding figures completely removed (I expect to avoid criticism from the NAO)?
I'm more than willing to judge Labour by what they publish and by their actions. Same deal with every other party. No one gets a by just because they're my guy. Everything is scrutinised and critical thought applied, and I don't see where this back story of them saving the NHS comes from judging by the information extant.
