Prince Harry has been appointed a Knight Commander of the Royal Victorian Order by his grandmother Queen Elizabeth II in a private ceremony in Buckingham Palace. The knighthood acknowledges Harry's service to both the Queen personally and the U.K.

Buckingham Palace announced the news on Thursday, June 4, saying in a statement, "The Queen has been pleased to make the following appointment to the Royal Victorian Order: To be a Knight Commander of the Royal Victorian Order (KCVO), HRH Prince Henry of Wales."

While officials refused to share any photos of the event, Kensington Palace posted on Twitter a picture of Harry's award along with caption, "Here's a photo of the #KCVO Insignia that The Queen presented to Prince Harry privately at #BuckinghamPalace today."

It's the first time for Harry to receive such an honor from her grandmother. The KCVO is a particularly high honor for the redheaded royal, as it's the unique knighthood awarded by the Queen herself, as opposed to those decided by ministerial recommendation.

Harry's uncles Prince Edward and Prince Andrew are both members of the same order. His brother Prince William doesn't have an RVO but he is knight of both The Order of the Thistle and the Order of the Garter. His father Prince Charles, meanwhile, holds ranks in the Orders of the Garter, Thistle and Bath.
