Mind you, rumour has it that a current very very senior naval bloke may have lost a briefcase full of stuff in the 90’s. So it may just all blow over… ;p
Longish story..
I drank in the Florence Nightingale pub, in the late80s/early90s – just off Westminster Bridge. There would be a mix of hospital staff, builders, accountants, MPs, workers from the Houses of Parliament, all sorts. Just after I left London, my mate got mixed up in a bit of a sticky situation, where someone had been offering around stolen computer stuff from the Houses of Parliament. I think my mate had been interested in buying some of it. The police turned up at the research unit where he worked and eventually interviewed him. Shortly after, the thief was found hanged – a genuine suicide apparently – in the HoP, leading to pub discussions about how he died, and whether he was entitled to a state funeral. (The rumour was that anyone who dies in the HoP is meant to have one. I don’t think that’s correct but it was a memorable conversation.) To my knowledge, nothing ever made it into the press about any of this.
