It really isn’t fair to brand him a sex pest. He is accused of having sex with a 17 year old in this country. That is not a crime. Additionally, that 17 year old chose to go back at least twice more to party with the rich and famous, so in my opinion although her claims, years down the line, hold no water at all, if it goes her way the spoils could be financially lucrative for her - which is what I believe is her purpose.
He is an arrogant, privileged, spoilt man used to getting his own way and stupid enough to choose his friends without due consideration, stupid enough to deny publicly all knowledge of their lifestyle, and stupid enough to hide from something that isn’t going away. Whether or not he knew what was going on no one knows at the moment, but even if he does eventually come clean, innocent or not, I don’t believe he has a working future of any sort in any area.
As an aside, I think at her age the queen could well do without the worry and embarrassment her favourite son is causing her - and her beloved self-exiled grandson and his dreadful self-serving wife. I feel very sorry for her.
