Nice spot, Floisme.
Given that the police should have informed the GP that the Coventry HQ was a crime scene, back when the charges were brought, it seems unlikely no-one other than Aimee knew about the charges against DC.
Similarly, there is the tweet from - agh!! What was her name?? - saying Aimee gave a false name for her father prior to his attendance at GP events in 2017-8. And the suggestion AC was told to do this.
If people in the GP did know, Caroline Lucas' statement just swims in cynicism: make it all about transphobia, all about AC, to cover up the question: who in the Green Party knew? What did the Green Party know?
