Over the last few years, royal watchers have been disheartened to witness the breakdown of the relationship between Prince Harry and his family, with lots of jaw-dropping allegations being made by the Duke and Duchess of Sussex during their tell-all interview with Oprah Winfrey and recent Netflix docuseries.
And it seems there's still plenty more to come from Harry's upcoming memoir, Spare.
The book, which is due to be published next week, includes allegations that Prince William grabbed Harry by the collar and knocked him to the floor following a heated row over Meghan Markle, The Guardian reports.
Sources close to the royal family say the Duke of Sussex would be branded a "traitor" because of Spare, but another expert has claimed that it's a good thing that the 38-year-old is finally speaking "his truth".
Psychologist Darren Stanton shared his thoughts with The Mirror on Prince Harry's family relationships and why he may have decided to share his story publicly now.
Speaking on behalf of Slingo, he said: "Prince Harry and William have been through a lot over the years, including one of the most traumatic experiences a child can ever experience, the loss of a parent.
"Then multiply that with the circumstances of your mother being one of the most famous people in the world, it's clearly going to have an effect upon your mental and physical well-being.
"When we experience trauma, especially as a young person, one of the things that some people tend to do is suppress it. The expression of a stiff upper lip denotes the mindset when people are encouraged not to show their feelings because it can be construed as a sign of weakness.
"However, the danger is that those feelings and emotions can be left untreated and manifest again in later life. The unconscious mind needs to deal with those experiences.
"Although Harry is part of the royal family, he is still very much a normal, functioning person that has thoughts and feelings as many of us would have if we lost a parent at an early age.
"My professional opinion is that the breakdown in relationship between Prince Harry and the family in the last few years has not been solely down to his relationship with Meghan Markle. I believe Harry may potentially hold a lot of anger and unsuppressed emotion towards The Firm.
"We do not know how his father and immediate family helped to support and guide him whilst dealing with the loss of his mother."
Stanton continued to claim that he believes Prince Harry is 'finally' ready to express his true feelings and, like his mother, won't be 'controlled' by others.
"It is common for people with past trauma to speak their truth and confront those to which they feel were responsible, which is why I believe Harry has spoken out.
"He's finally ready to speak his mind. He no longer wants to be controlled or mentored by the Royal family. In my opinion, this behaviour is extremely similar to something that Diana would have done."
He added: "Just like his mother, Harry clearly has a passion for humanitarian causes. From his non-verbal communication, he is very much a kinaesthetic person, which means he responds to his gut instinct and feelings. He obviously knows he has a platform now and isn’t afraid to express his true feelings.
"It’s clear we are going to see a lot more from Prince Harry in the coming months and years."
This comes after a clip from Harry's upcoming Good Morning America interview, revealed that he thinks his mum would be 'sad' about his relationship with his brother at present.
"I think she would be sad, I think she would be looking at it long-term to know that there are certain things we need to go through to be able to heal the relationship," he said.
Prince Harry's memoir Spare published by Penguin Random House will be available to buy in the UK on January 10.
