Got any UK government conspiracies?
That whole "paedophile ring in the top layers of media, government and the military who have been raping and murdering kids for decades and covering it up" thing is the go-to one.
One of the supposed victims is in court right now for allegedly wasting police time.
Oh yeah and that "having spies in every part of every Irish republican group, some who were in positions where they could prevent attacks without blowing their cover, but were allowed/ordered to let them happened anyway" one.
