It's now too late for a reconciliation between Prince William and Prince Harry, the author of an explosive new book has claimed.
And he says he believes it's down to Harry's wife Meghan Markle's "tendency to play the victim".
There has been much made of the rift between the two brothers with their frosty relationship reportedly sparked by William's concerns over Harry's fast-developing relationship with Meghan ahead of their royal wedding in 2018.
The tense row quickly boiled over - with Harry claiming his brother was "trapped" within the royal system during a bombshell interview with Oprah Winfrey after quitting as a senior royal.
The two brothers have hardly spent any time together since and were not picture together in public during the Queen's Platinum Jubilee celebrations last month.
Author Tom Bower, whose bombshell book on Meghan called Revenge: Meghan, Harry and The War Between the Windsors was published last week, examines the rift between the brothers and Meghan in his new release.
And he told OK! magazine that he thinks it is “too late” for a reconciliation between William and Harry because of “Meghan’s tendency to play the victim”.

He added that when Harry and Meghan stepped down as senior royals, relations between William and wife Kate with Harry and Meghan "had broken down".
The author explained: "At the heart of their divergence was Meghan’s unwillingness to be part of a team. There was no intimacy.”
“Meghan had convinced Harry that William’s staff were smearing her. Whispers about a tiara, that Kate had cried, her own demand for aerosol in St George’s chapel and now the staff’s outrageous complaints about her behaviour were, she said, invented to undermine her.”
Among the other allegations in Mr Bower's book are that Meghan threw a cup of tea in the air during a Royal tour, while the Queen was said to be pleased the duchess couldn't attend Prince Philip's funeral.
The book also claims that Harry and Meghan wanted to appear with the Queen on Buckingham Palace's balcony during the Platinum Jubilee celebrations last month.
The biography comes as it has been reported that Harry's own eagerly anticipated memoir will be released later this year - in time for Christmas shoppers.
It is claimed that Harry's book, which the prince has described as a "truthful and wholly accurate" account of his life, is now written and has been signed off by lawyers.
It is hoped that the book will be released later this year around Thanksgiving in the US in late November in time for the Christmas market.
A publishing source told The Sun : “The manuscript has been finished and gone through all of the legal processes.
"It’s done and out of Harry’s hands. The publishing date has been pushed back once but it is on track for the end of the year.”
