//many died because the government was too busy celebrating Brexit to do anything about Covid. Boris first addressed the nation on March 9, when four people had died, but lockdown didn't begin till the 23rd (and a lot of restrictions from the 26th).
That delay was lethal. Countries that acted more quickly lost fewer citizens.//
I think you need to research how the long term impact of lockdowns is now manifesting itself. No other pandemic in history had been dealt with by locking people down in their homes and closing vast swathes of business and industry. The UK had a plan for dealing with a pandemic and it involved nothing like that. It is now becoming evident that the hastily devised so-called cure will produce far more unpleasant results than the disease (as explained in the link I provided). All that lockdowns did was to delay the transmission of the virus. The long term effects of lockdown were never properly considered (or if they were they were dismissed) and they are now becoming apparent.
The link I provided earlier explains that currently each week more than twice as many people are dying from undiagnosed and untreated conditions, the lack of attention stemming from the Covid measures, than are dying from Covid. Covid deaths held the headlines for the thick end of two years, but where are the headlines containing these figures?
//Brexit has nothing to do with it? Staff leaving in droves or being off sick has nothing to do with it? The treatment of the NHS by the UK Government has nothing to do with it?//
Yes the loss of some staff following Brexit had an influence. However, many left when the first lockdown was imminent, not fancying becoming marooned here and unable to return to their home nations. I don’t know what you mean by “the treatment of the NHS by the UK Government.” All the government seems to have done is to lavish stupendous amounts of money on it, a large proportion of which has simple been pee’d up the wall by engaging more and more non-medical staff. Lockdowns are definitely responsible for the effective abandonment of primary care, with many GP surgeries largely shutting up shop and referring anyone who might need the attention they could provide to A&E.
Back to the question (inflation): it is barely beyond dispute that the principal cause is the unstable situation on the international energy market. But the UK’s woes in that respect are the result of the abandonment by successive UK governments of any effective policy to maintain energy security. This country has ample supplies of fossil fuels but their use has been sacrificed on the altar that is “Net Zero.” But it is also barely beyond dispute that the printing of more than £400bn of worthless money, used to pay people to sit at home and do nothing for up to two years, played a big role.
