BBC Presenter Huw Edwards explained: "The Queen, wearing a red silk dress which reflects the heritage of the Grenadier guards, because she's, of course, the new colonel of the Grenadier guards."
Camilla sat alongside Kate, Princess of Wales in the carriage behind King Charles and Huw said this was "her first state event as the Colonel of the Grenadier guards" and she paid homage to her role with her dress.
The headline appears to be based on a YouTube video that was posted in 2021. The video claims to show a recording of a phone call between Harry and Davy, but there is no way to verify the authenticity of the recording.
The video has been shared widely on social media, but there is no credible evidence to support the claims made in the headline. It is likely that the video is a hoax, and that the headline is simply clickbait.
It is important to be critical of the information that you see online, and to only share information from credible sources. If you see a headline that seems too good to be true, it probably is.
