Prince Harry is waiting for a “grovelling apology’ from Prince William and Princess Kate before he will be reunited with his family, according to a royal expert.

Last week Kate revealed she has been undergoing cancer treatment after it was found following abdominal surgery in January, which has kept her away from public duties and appearances. As she confirmed her health update via a moving video address, it is thought that she and Prince William might expect a visit from Prince Harry shortly. The Duke of Sussex is expected to return to the UK in May for a celebration of the Invictus Games, with a meeting between the brothers thought likely.

However, it now appears that Harry will be expecting an apology from the pair. Royal expert and author Tom Quinn exclusively 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 can build a relationship with their cousins, as 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 ‘ health news being made public on Friday, Harry and Meghan shared a short statement. They said: “We wish health and healing for Kate and the family, and hope they are able to do so privately and in peace
