I noticed that someone drove Eugenie to the POW's birthday last week and Jack was in the back seat.
Strange. To me anyway.
I really would have thought, no matter what water had passed under the bridge between Diana and the RF, and what ever you think of Diana's actions, that for the sake of her sons the RF would have dealt with her security. It was never rocket science to predict what might happen to her. Especially in those first years after the split from the RF, with press interest at white hot.
