They gamely presented a united front in the aftermath of the Duke of Edinburgh’s funeral, strolling side by side and chatting amiably as they emerged from St George’s Chapel into the sunshine. But the Duke of Sussex, 36, was afforded a rare opportunity to have a proper heart to heart with his brother, the Duke of Cambridge, his father and his grandmother on Saturday, as they returned to the confines of Windsor Castle. There, a couple of hours after the ceremony, when most other guests had melted away, senior members of the Royal family spent around an hour together, face to face for the first time in more than a year. There, reunited in grief and in their support for the Queen, Prince Harry is understood to have spent valuable time with Her Majesty, Prince Charles, the Duchess of Cornwall and the Duke and Duchess of Cambridge. It was the first time they had been together under one roof since the Commonwealth Service at Westminster Abbey last March, when the frostiness and the tension was palpable. The group remained locked in conversation, no doubt comforting the Queen in her darkest moment. But it would have been odd had they not also addressed the elephant in the room, the Duke’s televised interview with Oprah Winfrey and the hugely damaging allegations made by both him and the Duchess. Aside from suggesting members of the family were racist and had ignored the Duchess’s pleas for help with she felt suicidal, the Duke accused his brother of being “trapped” within the monarchy and said he felt “really let down” by his father. In response, the Queen said the “serious allegations” would be addressed privately, but added that “recollections may vary”. The Duke of Cambridge was understood to have been furious by the turn of events, while Prince Charles, 72, was said to feel “let down” by his son and daughter-in-law, whom he had supported “more than he would care to say.” But on Saturday, they were there to support the Queen and it was she, more than anyone, who has been desperate for her family to get together and resolve their differences. If anyone is the driving force behind a reconciliation, it will be the sovereign, sources insist. But while conversations may have begun, they were brief. The group are thought to have had around an hour together. Most of the 30 mourners are thought to have left Windsor Castle shortly after the service. Princess Eugenie and Zara Tindall have newborn babies, while the Earl and Countess of Wessex were there with their two children. The Duke of York left shortly before 5pm, while Prince Charles, the Duchess of Cornwall and the Cambridges, all left at around 6pm.
