One thing we never really had to face here was one country or region getting the blame for spreading covid to the rest of the UK - there was complaining at points about e.g. people leaving London the day it went to Tier 4, but on the whole it's not like anyone thinks the rest of the country would have been fine if it wasn't for London or anything like
I disagree. The animosity towards Londoners has been a feature in the UK (stoked by governments) for a while even before Covid. And there absolutely was breathtaking hypocrisy re Covid. It was fine for Londoners to be put at risk by people coming from across the UK (and abroad) bringing Covid to London. But the first hint of Covid possibly being spread from London had police roadblocks Keeping Londoners out and people telling visitors to Go Home.
can’t imagine Sadiq in London arguing with Andy Burnham in Manchester for example or refusing to help.
No but it did happen the other way. London, despite being a higher risk as a densely populated urban international travel hub with overcrowded housing and a huge amount of deprivation, got a lower share of vaccines at the start of the UK rollout.
Regional division, whilst unpleasant and regrettable, is definitely not something unique to Australia.
