Prince Harry still expects a “grovelling apology” from William and Kate, according to a royal expert.

In March, the Princess of Wales revealed she was undergoing cancer treatment after it was found following abdominal surgery in January, which kept her away from public duties and appearances.

As she confirmed her health update via a moving video address, it was thought that she and Prince William might expect a visit from Prince Harry.

The Duke of Sussex returned to the UK in May for a celebration of the Invictus Games, with a meeting between the brothers not taking place. However, it appears that Harry will be expecting an apology from the pair.

Royal expert and author Tom Quinn told The Mirror: “He wants to reconcile with his brother so that the children can have some kind of a relationship, but he and Meghan still think that a grovelling apology needs to come from William and Kate first.”

Quinn also revealed that Harry is keen for his children to build a relationship with their cousins.

He added: “Harry has spoken to friends about his sadness at not have a closer relationship with his niece and nephews, but what is upsetting him even more is the prospect of Lilibet and Archie having no relationship at all with George, Charlotte and Louis.”

The royal expert added: “He has implied that if he gets an apology from his family then he is prepared to forgive, but that just isn’t going to happen.”

In response to the Princess of Wales’s health news being made public on Friday, Harry and Meghan shared a short statement.

Former royal butler Grant Harrold suggested that the Firm might agree on burying the hatched if the Duke agreed to apologise for the cutting remarks he made in his autobiography.

But speaking to Sky News Australia, commentator Dee Dee Dunleavy claimed: “(Harry) is not going to apologise, at least not while he is still with Meghan.

“I really do believe he does her bidding and she is never going to allow him to apologise to the family.”
