Well I mentioned this on Richard's recent video on his Odysee channel where he's talking to James Delingpole about Manchester. Richard replied saying he wants to give the story a wide berth as he feels the story was used to get people like himself talking about and making videos and coming to the wrong conclusions so that they had an excuse to censor people. Not sure what you mean about Paul Bulley, you probably mean Paul Ansell. Peter Hyatt did a video about Paul where said that he felt Paul was being truthful.
There's been many claims and theories, but one I read recently was a Substack article talking about links to organsed crime, drugs trafficking, snail farms, Italian Mafia, fraudulent businesses etc. Paul Ansell worked at BAE Systems, and Nicola's father runs a freight company, so maybe there's some connection there.
