Guardian leak intersects with Sunday Times leak. Not only was Cummings a potentially distorting filter of the SAGE advice. Johnson absented himself from COBR - the forum where the advice is explained. So his actions were informed, not by the science, but Cummings’s version of it.

It’s a double-whammy. A PM who kept himself, either deliberately or negligently, clueless on the biggest existential threat facing the country, led by an adviser notorious for pseudo-science and half-understanding, allowed to insert himself and contaminate the scientific process.

And this is why the UK will end up with the highest death toll outside Trump-addled America, even though we were one of the countries blessed with the most information and ample time to prepare and react.

Let the headbangers, headbang. This is all there is to it, in the end.
