On Sunday 10 November, the nation will come together to remember those who sacrificed themselves for the freedom of future generations, and on Saturday night the Cambridges and Sussexes will reunite at the Royal British Legion's annual Festival of Remembrance.

Speaking about his perceivably strained relationship with his brother, Harry said: "The majority of the stuff is created out of nothing but as brothers, you know, you have good days, you have bad days."
The Cambridges updated their profile picture

Records published under the Intellectual Property Office list an application for a trademark entitled Earthshot Prize from the Duke and Duchess of Cambridge's charity The Royal Foundation. It became William and Kate's principle venture, after the Duke and Duchess of Sussex branched out to create their own organisation earlier this year.
Within the application, it states that the trademark name could be used for photographs, clothing, footwear and headgear, as well as education and training services, publishing, cultural activities, competitions and awards and all relating to nature conservation and the environment.
