If she’s playing a Californian bizzfluencer, fair dos, but if she’s there as the wife of a British prince and a Duchess, then I hope BP will take a good look at whether this breaks the Sandringham agreement and take swift action.
The only good thing about the Andrew fiasco is that it has opened a route for the rf to clear out its dross.
