The Government of the UK paid for their trip to SA. The last couple of days were clouded by their court action and Harry's statement. They are not the first Royals to bring a court action and it will probably succeed as its about copyright. Her letter belonged to her as she wrote it; in copyright terms.
The wider problem they have is not accepting any criticism. Some of it is way over the top but they have accepted public money to renovate their house (£2.5 million), they fly in private jets whilst saying they care for the planet and warning others, and they cannot open car doors! No info about Archie's god parents and various other press bans have put the press into attack mode because We Are Paying For Them! It all seems very entitled without understanding the public will want certain information about them, and have a view on their habits, if they pay out money for them.
She is no Michelle Obama. She wants to be. She is wanting a Royal platform for what she wants to say. Hardly any celeb says anything worthwhile. It's generally scripted and bland and hand wringing (Charles has this off to a tee). It should be more about actions but she won't do much. The second son of the royal family always has problems. Look at Andrew. What has he achieved?
This published statement from Harry was posted without any input from his advisers. They have made that clear. The Palace is angry it was posted before the end of the tour with no consultation. No one was involved with this. They have moved from the normal Royal Solicitiors who handle court cases on newspaper complaints, eg Kate in South of France topless pix etc. to their own solicitors. This is H&M striking out on their own. She does keep losing staff and is probably difficult to handle in a Royal way. We will see how long the latest appointment lasts regarding their PR. Not long if she is not consulted I guess.
