The biggest issue for me in all this is that it demonstrates the corruption of the RF. The Queen is in a position to be able to prevent the Met from pursuing criminal proceedings progress in this country, as part of her Head of State remit. So sure as hell, PA wont be investigated by police here.
So that leaves the US. Given that the furore with PA and The Sussexes is already seen as threat to the Monarchy, then the easiest way to get the RF off the hook would be for PA to help the FBI and be found innocent of all involvement.
That PA hasn't done that, speaks absolute volumes. Whatever he could reveal must surely have worse implications for the RF than keeping schtum and pissing off the public that way.
I have always been a royalist until now. That is rapidly changing.
