I think you have a valid point Trimmy. It isn’t down to just one person, but ultimately, as you say, it is he who must carry the can as he is ultimately responsible.
If we are an outlier amongst countries as in more cases, lower recovery rates/higher death rates then it should lead to uproar and a new government. However, as mentioned elsewhere, it may turn out that enough peeps blame Labour/Jeremy Corbin for this and we carry on with the oafs in power.
