There is a different perspective. Two days after this party the allegations about Dominic Cummings and Barnard Castle hit the press. Johnson and the Tory Party rallied around him, we had that ridiculous press conference in the very same Downing St gardens that the parties took place where he said he was testing his eyesight and Cummings survived when many thought that not possible. The result was the hitherto strong levels of lockdown compliance weakened when people saw someone of power applying different rules.
I suspect that the reason Johnson and his cronies rallied around Cummings was because they feared if he was let go details of the parties would soon emerge and do for a few of them.
I would presume Cummings and his associates are in "Revenge is a dish best served cold" for his ultimate departure at the alleged behest of Johnson's wife. Who knows what else will filter out if this one doesn't finish him off!
