And this one is from the US-based Commonwealth Fund in 2017:
When you hear the right wing say the NHS is inefficient, it isn't. Nobody does it better with the resources they have got. To claim otherwise is to talk nonsense.
On the other hand, they can't work miracles and the reality is we don't get the healthcare we need, and that is down to money. We just don't spend enough to get gold standard care.
Is £20 billion enough extra? It helps. But it only helps.
And let's be clear, if all these other countries can find the resources then so can we. And we still don't need to raise extra tax to do so. This country needs to run a deficit.
