If Boris hires someone to lead his team who says Whitehall departments are "useless as communication devices" and then leaves covid messaging to those departments, is people not listening Boris's fault? If he does not use any of the social media methods that won him a referendum, party leadership and a general election, is people not listening Boris's fault? Where the fark are the UK cat and dog memes or tiktok dances supporting the rules? Look at what government is putting out online - it's so dry, you wish you could stuff your rain-soaked shoes with it!
If Boris's failure to communicate effectively (and refusal to see this as important enough to use the sharp tools) isn't Boris's fault, then whose do you think it is?
Boris made his choice months ago. Bet everything on vaccines and try to hold his party together long enough to deploy them. Suppressing peaks was just a way to stop MPs taking so much heat over NHS collapses that too many would rebel.
