There is something in particular between the brothers that could be the cause of their estrangement.
Prince Harry has found his passion and dedication in the Invictus Games. These sports games, created in 2014, have become a platform for veterans and service personnel, enthusiastically led by the Duke of Sussex, who has managed to raise impressive funds for their continuation, as highlighted by Robert Johnson in the ABC News special 'Prince Harry's Mission: Life, Family and Invictus Games'.
According to information provided by the writer, he suggests that the success and commitment of the youngest son of King Charles and Diana with the Invictus Games could have surprised Prince William, generating some jealousy between the brothers. The magnitude of the event and the involvement of multiple governments could have been a source of astonishment for the future king, possibly creating tensions in their relationship.
The recent visit of Meghan Markle's husband to the United Kingdom due to King Charles' diagnosis did not include a meeting with her brother, which royal commentator Victoria Murphy considers a reflection of existing tensions. Although the news about the British president's health could unite the royal family, differences between the brothers persist.
Prince Harry has emphasized the importance of family unity in difficult times, although physical distance and personal obligations may affect the frequency of family gatherings.
Despite the success of the Invictus Games for the sovereign's second son, his relationship with his older brother, Prince William, is marked by uncertainty and emotional distance.
