Ferguson is not the person to go under that particular bus because he is seen as a major influence for plan B, lockdown, not plan A (Boris the butcher).
Thats why phrases such as 'Prof Ferguson, whose advice to the prime minister led to the UK lockdown' are prominent in BBC coverage of the story. Its those who hate the lockdown and the models that lead to it, or those that hate his own behaviour during lockdown, that would have it in for Ferguson.
No pressures on the government for any of their most obvious failings are relieved at all by what has happened to Ferguson.
