Royal experts have claimed Prince William and Prince Harry's relationship is still not on the mend, despite the brothers being seen chatting after Prince Philip's funeral in April.
Apparently, things were still so bad between them at that stage that they broke out into an argument once they were behind closed doors after the service.
"Truth be told, Harry didn't really know what to expect before he came home, which is why he reached out before seeing everyone," Robert Lacey, the author of Battle of Brothers told the Daily Mail.
"He wrote a deeply personal note to his dad to try and set things straight, but tensions are still running high and things haven't exactly ironed out the way he had hoped."
A source claims that although Harry and William were spotted chatting outside of St George's Chapel in April, within minutes of getting inside the castle and away from the prying eyes of the public, the brothers were at each other's throats "as fiercely as ever".
"The rage and anger between those two has grown so incredibly deep," the source reportedly told Lacey. "Too many harsh and wounding things have been said."
The royal expert also revealed there wasn't a "family sit down" with their father Prince Charles to talk things out.
"There was no reconciliation, and no brotherly sit-down or 'mini summit' following Prince Philip's funeral on April 17," he said.
"The conflict between Diana's two bitterly divided sons does not seem likely to end any time soon."
The brothers' relationship has been damaged due, in part, to the numerous bombshell interviews Harry and wife Meghan Markle have given about the royal family.
A friend of Harry and William told Vanity Fair, "There have been conversations, after Lili was born and to make plans for next week, but things are still very strained."
Harry flew into the UK alone, despite rumours he might fly in with son Archie, two. Meghan remained in California with Archie and their newborn daughter Lilibet.
The Duke of Sussex is saying with his cousin, Princess Eugenie, at Frogmore Cottage in Windsor, where he is able to quarantine for the required five days before being tested for Covid-19.
