When you actually read Tomlinson's evidence you learn that he only thought about this after watching a documentary on the crash in 1998, a year later. So it was telly that led him to the conclusion, along with a mysterious claim, maybe genuine, that there was a plan to assasinate Milosevic in a tunnel in a similar way by MI6, ergo, the so-called 'flash' in the tunnel 'could' have been black ops MI6 spooks rather than paparazzi taking pictures. Plus he's a former spook so he must know right?
Of course, the Express will no doubt be happy as they will be able to get Diana in the column inches once again, just next to Madeline McCann. Incidentally if you wonder what the obsession of the Express is really all about I have the scoop on that from an Express hack. Apparently 'dead blondes sell papers', funny but I thought their circulation was down.
