PRINCE WILLIAM is reportedly "saddened" after hearing his brother Harry's comment about their father, Prince Charles.
Last week, Harry appeared on a US mental health podcast, where he spoke about his life as a royal and controversially criticised the First Amendment of the US Constitution, the right to free speech.
In the latest in a growing line of swipes he's taken at his family in recent weeks, Harry slammed Charles' parenting, and indirectly criticised the parenting skills of the Queen and the late Prince Philip.
He said by leaving the royal family and moving to the US he was trying to "break free" of the cycle of "pain and suffering", which he says is handed down from generation to generation.
Harry suggested that Charles treated him badly because he himself had been treated badly as a child by his parents.
According to sources at the Daily Mail, William was hurt by Harry's decision to once again take his family grievances public.
"Prince William is, of course, saddened by the recent developments because of the way Prince Harry is putting such deeply personal pain into the public domain, invading all the family's privacy," a royal insider said.
"It is fair to say that, even now, William does privately have conversations about the relationship with his father, which has been strained in the past.
"There was much hurt after his mother's death and both brothers at times found their father's commitment to his work difficult to comprehend."
The source added Charles and William now have "a lot of mutual respect" and the Duke of Cambridge "would never even comprehend for one moment speaking publicly in the way Harry has done in the past week."
Harry is expected to return to the UK for the unveiling of a statue dedicated to his late mother Princess Diana on July 1, a ceremony he's due to take part in alongside his brother, but this latest incident has put that all into question.
