I would say...
Many years of underfunding, neglect, secretly privatising the NHS, running it down, trying to introduce US Healthcare processes- it’s no surprise the NHS was under strain. An average Conservative does not believe in an NHS, it’s an alien concept to them. So they cut funding, lost nurses, refused pay rises, started deporting key medical staff etc etc. But Boris is just the latest of people do that, that started before him. Not all on him. You could even say he’s unlucky that this happened on his watch because whenever it happened the guy in charge was going to have a tough time after they’d stripped the NHS to the bone.
What is on him, and only him, is the shambolic response he’s been in charge of. Virtually every single thing he had to do he got wrong. Wrong advisors, wrong advice, wrong strategy, bad communication, no equipment, all compounded by piles of lies and his usual routine of disappearing completely as soon as the going gets tough. It was always going to be hard going, but the actions of this government have exponentially made it worse. Any other walk of life and he’d be immediately sacked along with a few more in there, in this case it’ll be spun into a triumph. Any success that does happen from now is down to the people in the NHS, and only them, it’s not the government- if we do get it under control then it then it will be in spite of the government.
As an example- these ventilators we keep being told are on the way, about to be ramped up- 10,000 from Dyson and all that great stuff. Good news is, we’ve got more ventilators.... 30 of them. Just watch the reaction on the face of the newsreader here, she can’t even hide the incredulity at it.
