Yes, specifically GCHQ, ASIO and CIA worked together to try and set up Trump and Co and entrap them in some kind of Russia scandal.
Two of note are the Russian lawyer meeting with Don Trump Jr while working with Fusion GPS and Christopher Steele and the other set up from the Aussie end was Alexander Downer meeting with Papodopolous in London and got drunk together as a kind of honey pot. Papodopolous got his special 'intel' from the English professor who has since disappeared (very strange).
And Skripal (the poisoned ex russian spy) is connected to Christopher Steele and both worked with MI6. I bet Skripal was one of Steele's 'Russian sources' for the dirty dossier.
Looks to me the poisoning and the professors disappearance are hits to tie up loose ends committed by the group attempting to set up Trump and his team.
Oh yeah, the other two 'projects' for the set up was 'Manafort' and Carter Page, both knowing or unknowing plants and both were under heavy surveillance.
