Kate told the touching anecdote while meeting members of the public on a walk outside Windsor Castle with her husband, the Prince of Wales, and the Duke and Duchess of Sussex. Banita Ranow, 28, was among the crowd on the Long Walk and said she heard Kate telling children next to her what her youngest son Louis had said about the Queen’s death. He said Kate told the children: “Louis said ‘at least grandma’s with great-grandpa now.’ Ms Runow said the Duchess of Cornwall and Cambridge “came alive” as she spoke to the children. The worshiper from west London also spoke of her surprise to see the two brothers and their wives together after long-standing tensions between the pair, adding: “It was really nice.” Mrs Ranow’s mother Baljinder Ranow, 64, said their reunion was “wonderful”, adding: “It was so beautiful to see.” William and Kate were joined by Harry and Meghan for a stroll through Windsor on Saturday (AP) She said: “I felt so emotional and I felt the Queen would love it. I just hope in the future it stays that way and siblings and families are united.” It was William and Kate’s first engagement under their new titles, Prince and Princess of Wales, and the first time they have appeared in public with Harry and Meghan since the Queen’s Jubilee National Service in June. However, the couples were not seen talking to each other and sat separately at the event. On Saturday’s walk they inspected flowers and balloons and greeted well-wishers. A royal source said the Prince of Wales asked his brother and his wife to join them to view the tributes. The last time Prince William and his brother were seen in public at Windsor Castle was at the Duke of Edinburgh’s funeral in April last year. Both couples left in the same vehicle as the engagement, which lasted more than 40 minutes, came to an end. Additional report from PA
