Prince Harry has claimed he and wife Meghan were betrayed by Buckingham Palace as they leaked stories to the press about the couple.
The Duke of Sussex, 38, is set to release his tell-all memoir Spare on January 9, with Royals bracing themselves for the revelations inside its pages.
Ahead of it going on sale the prince has given two separate sit down interviews set to be broadcast on Sunday in the UK and the US.
In the States he made a number of damning allegations in his chat with Anderson Cooper of CBS, as he claimed his family planted stories about him and his wife.
He complained: "Every time I've tried to do it privately, there have been briefings, leakings and planting of stories against me and my wife.
"The family motto is never complain, never explain – it's just a motto.
"They will feed or have a conversation with the correspondent and that correspondent will literally be spoonfed information to write the story.
"At the bottom of it, it will say they've reached out to Buckingham Palace for comment – the whole story is Buckingham Palace commenting.
"So when we're being told for the last six years 'We can't put a statement out to protect you' but you can do it for other members of the family, there becomes a point when silence is betrayal."
His second interview was with ITV ’s Tom Bradby, a friend of 20 years, and will cover a range of subjects including his personal relationships, never-before-heard details surrounding the death of his mother Princess Diana and a look ahead at his future after quitting the royal family alongside his wife Meghan.
In a first look clip , Harry said he wants his ‘father and brother back’ following the breakdown of his relationship with Prince William and his father King Charles III.
He told the newsreader: "It never needed to be this way, the leaking and the planting, I want a family – not an institution.
"They feel that it's somehow better to keep us as the villains. They've shown no willingness to reconcile.
"I would like to get my father back. I would like to have my brother back.”
Michael Jermey, ITV Director of News and Current Affairs, said the interview will be something 'everyone should want to watch' as Harry prepares to reveal all about his family.
He said: "It is extremely rare for a member of the royal family to speak so openly about their experience at the heart of the institution.
"Tom Bradby’s interview with Prince Harry will be a programme that everyone with an informed opinion on the monarchy should want to watch.”
