All it would require for a divorced person to succeed to the throne is an Act of Parliament.
Murdering anyone wasn't necessary and the risk/reward ratio is out of whack.
If it were provable that the royal family actually plotted her death, the monarchy would come to an end.
That's a far worse outcome than a divorced monarch.
"If it were provable that the royal family actually plotted her death ...."
But there's the rub. Prooving a well-executed operation can be very difficult.
But what do you think of my assessment of the Windsors?
True, but had this relationship had the chance to take off, it would have been yet another "embarrassing" stunt for the self absorbed Windsors to have to deal with. Remember, Fergie and the toe sucking, all of the secret phones calls etc? That said, I do believe it was an accident.
