Hardly news, most if not all the Royals go through this at some point. Rumour mill at the time was that one of Di's new hair styles was due to an incident with some singed hair courtesy of the Desmonds on some drills they were doing with her over at Creddenhill or wherever they were back then.
The Hooligans just fancied sh1tting her up in the killing house. Can see it now as she sits demurely amidst the tyres and fig 11s on a chair with just a few too many bullet holes, burn marks and something that looks like a blood stain.
Then it all goes bright and loud and next thing you know the fig 11s are going everywhere...
