It is thought to be the first time royals have been seen in public together since March 2020
Harry and Meghan have appeared at Windsor Castle to greet well-wishers during the second day of national mourning.
The Duke and Duchess of Sussex arrived with the Prince and Princess of Wales at Cambridge Gate earlier this evening. It is thought to be the first time the couples have been seen in public together since March 2020.
Harry and William have not been seen in public together since the funeral of the Duke of Edinburgh last year. The duke was pictured leaving Balmoral Castle alone on Friday morning after the death of his grandmother.
A spokesperson for Prince William said he invited his brother and sister-in-law to join him and Catherine to look at the tributes and flowers left outside the royal residence.
Security barriers were placed around the area as crowds – at Windsor paying their respects to Queen Elizabeth II – erupted into cheers at the impromptu appearance.
The duke and duchess held hands as they read tributes. Both couples, who were dressed in all black, then spent 40 minutes speaking to members of the public.
William and Kate walked along one side of the road as they greeted people, while Harry and Meghan walked along the other.
