Is the idea of a reconciliation between brothers Prince William and Prince Harry a bridge too far? Perhaps the six-part documentary Harry & Meghan, released this month on Netflix, is not helping the cause at all. (The same could be said about Harry's memoir, Spare, which will be released on January 10.) What about Harry and Meghan's invitation to Prince Charles' coronation in May? According to some sources, Harry and Meghan will be invited.

"We can't let these people go to the king's coronation," says royal expert Angela Levin. 'It's an important occasion and it can't just be them [Harry and Meghan]. William said, 'Absolutely not. You can't come,' he would say."

Of the members of the royal family, it was William who, at least in the opinion of the author, was portrayed most negatively in the docu-series, "He is the most frustrated about all this and today, once again, dragged him through the mud," Levin says.

In particular, the part about the so-called "Sandringham Summit," revealed in the second volume of the docu-series released this past Thursday, is particularly damaging to William and Harry's relationship, which experts say is likely to be irreparable at this point. In Harry & Meghan, Harry says of the summit, "I was in the middle of it, and I was in the middle of it, and I was in the middle of it. And my grandmother just sat there quietly, taking it all in". [Royal family expert Richard Fitzwilliams says. It was "well-crafted, destructive, and especially cruel to William. After the claims about the Sandringham summit, there is no doubt that the rift between the brothers [will be] irreparable."
