Prince William, Princess Kate, Prince Harry and Meghan Markle reunite to meet mourners

Much to the delight of royal fans, Prince William and Prince Harry, along with their wives Kate and Meghan appeared together in an extraordinary walkabout at Winsdor Castle, reunited in their grief for Queen Elizabeth II.

The four walked together to meet and greet mourners - Harry and Meghan had apparently been invited by the newly minted Prince of Wales to join him and Kate.

Royal watchers have described it as a "significant moment" for the two brothers.

One royal fan who spoke to Harry and Meghan told the Daily Mail: "It's lovely to see them both together. Maybe they can get back to a proper relationship. [A] lovely ripple went through the crowd as they approached.

"Hopefully, the healing between Harry and his brother can start now. I'm just so excited to have seen them both together. It's lovely."

The appearance is thought to be the first time that the two couples have all been in public together since Commonwealth Day on March 9, 2020.
