A royal expert says Prince Harry and Meghan Markle are on "very dangerous ground" if they share any private information following the Queen's Jubilee.
According to one source, Prince Harry is furious at the royal family over his treatment during the celebrations.
Royal biographer Angela Levin told The Sun that Prince Harry, the Duke of Sussex, believed the family "largely ignored" him and he would have been "very, very upset".
"He still feels he's owed an apology.
"But he's the one who should apologise. He said during the Oprah interview that Charles and William were trapped, he said he'd been cut off by his father.
"You can't just go around being rude about people and expecting them to open their hearts to you again."
However royal expert Duncan Larcombe said the fact that they were involved in public celebrations at all clearly shows "an olive branch has been extended by the Royal Family here".
"They have come to the UK and to the Jubilee and really cemented themselves as royal again, which is great for their brand and something that Spotify, Netflix and Penguin will be eating up," he said in this week's Closer.
But he said he believes the Royal Family doesn't entirely trust the Sussexes anymore and will be watching with an eagle eye to see if the pair will use their visit for content purposes.
He said if any private information from the weekend was revealed to the press or published in a book, there would be no coming back from it.
"It's last-chance saloon for them now," he said.
"I imagine they will be totally cut off and that'll be it. It's very dangerous ground if they betray anyone now.
"But if they act appropriately and prove they be trusted, it could be a huge step in the right direction and the start of a new beginning."
