Prince William will not talk to Prince Harry until after he has published his explosive 'tell-all' book, according to a royal expert.
Despite the Duke of Sussex staying only half a mile away from his older brother at Frogmore Cottage during his brief UK visit this week, it is reported they have not met up yet and have no plans to.
William, now living with Kate Middleton and his family at Adelaide Cottage on the Windsor Castle estate, is thought to be wary Harry may choose to include the content of their private conversations in his upcoming memoir.
Royal biographer Angela Nevin said this would likely continue to be the case until the Royal Family knew what was in the book.

She told The Sun : “I think it's likely that Catherine and William will try to avoid any contact with Harry and Meghan until they know the contents of Harry’s memoirs and their Netflix documentary.
"They have lost their chance of being trusted as the chance is they will use any conversation.
“It’s their own fault for vastly exaggerating and being rude.”

It comes as the California-based royal is still expected to release his delayed memoir by the end of 2022, which he promised would give an "accurate and wholly truthful" account of his "highs and lows, the mistakes, the lessons learned".
Revealing he would be publishing the ghost-written book in a reported $20million (£15million) deal last year, the 37-year-old royal added: “I’m writing this not as the Prince I was born but as the man I have become.
William is not thought to be alone in having his suspicions roused by the memoir, with other members of The Firm previously said to be nervous about communicating with him over what he might leak to the media.

Last December, a friend of Harry’s claimed that the book would “shake the monarchy to the core” and will go into detail about his true feelings about the royals.
The friend told the Mirror that deal required him to include "personal details of personal and family arrangements".
Prince Harry will appear at two charity events this week before travelling on to Germany for an Invictus Games event.
