I have now watched the full Cummings interview.
Whilst he may be discredited because of his eye related covid adventures and consequent lying, his interview is damning on Johnson, I can not recall another interview quite like it. He has basically trashed Johnson and shit all over his head.
The important point though out of it all in my opinion is what effect the interview has on the upcoming public enquiry. Cummings has removed the first brick and at the enquiry those closest to Johnson have to answer under oath and if Cummings account is vindicated as being correct the whole house could cave in, in fact the Tories as a party could implode.
With Labour currently a shambles, a Tory party disintegrating could reshape UK politics for a generation and it is quite feasible we have a complete realignment of UK politics.
A vacuum like that is either scary or quite an opportunity depending on your political persuasion.
