The Telegraph (Ok, not impartial) has today (Sunday) quoted a blog from Dominic Cummings (possibly the source of anti-Boris briefings) which sheds a whole new light on 'Partygate':
"Because No10s political and communications operation has imploded, it has failed to explain something very obvious to anybody working there at the time: No10 staff were ENCOURAGED to have meetings in the garden April-August for the obvious reason that we were in a pandemic with an airborne disease and being outside was safer! all day every day in this period there were many work meetings in the No10 garden."

Adds a new perspective?
