It will look bad on Charles and his inability to “control” his son. No one is looking to her majesty to manage the family anymore, it’s up to Charles.

Harry is an adult. Most people can easily see that the fault lies with Harry, not his father. All of this is a result of Harry’s actions, not Charles.

I don’t think Elizabeth was scapegoated for Margaret’s marriage failing so publicly back in the early 70s. Most people with kids know that once your children are adults that they are no longer in your “control.”
