Several of the failures are due to historical things that aren't due to the current government.
Well i suppose thats whether you count the current government as Boris and his cabinet or the Conservative government that has been in power for the last 10 years (of which at various points Boris was in the cabinet), as its unquestioned that if you look at the last 10 years it is the Conservative government that has cut the NHS laboratory testing capacity & PPE stock pile which has had a direct effect on are ability to deal with the current pandemic.

but the fact those plans weren't good enough isn't something that the current government are to blame for
Apart from the late lock down which we can lay clearly at Boris's door.

The trouble is that the death rate is a lagged factor, so the decision on timing is actually based on the predicted rate in a few weeks.
China, South Korea, New Zealand all had there new cases and death rates significantly lower when they reopened, and they have been pretty successful why cant we follow that model why take the risk for the sake of a week or 2?

It's a very tricky balancing act with no possible "good" outcome, and based on interviews with various independent experts I feel that the timing is roughly as-good-as-it-gets.
Surely a good outcome would be to be able to reopen without getting a spike in infections soon after, and a bad outcome would be the opposite as it would lead us back into lockdown of some sort?
