In an ideal world: we would have a situation where each large “island” like Britain is controlled under one government. Using a devolved system on an island like this has inevitably lead to differences in approach. Sturgeon and Drakeford want to be “the one who eliminated the novel coronavirus and saved the population”, although this may be political. Johnson seems to be using a “hammer and dance” approach, which essentially allows the virus to spread through the population whilst stopping any more serious outbreaks from occurring.
On an island like this, these differences in strategy are going to inevitably lead to problems, for instance Sturgeon threatening to close the border and Johnson dismissing this as “absurd”.
I'd be wanting that one Government not to be Westminster that's for sure, comparing the rates of Covid-19 infections between North West England and Scotland (or Wales). I still think it was absurd that the UK Government didn't restrict border movements into the UK back in March, that was a key part of why many other European countries have been more successful in fighting the virus.
