Thomas Markle's behavior and his interactions with the media are central to the reasons behind Prince Harry and Meghan Markle's departure from their roles as senior members of the British royal family, an author claims. The Duke and Duchess of Sussex announced in January 2020 that they intended to step back from their royal duties to become financially independent while still supporting Queen Elizabeth II.

Clare Foges, writing for the Daily Mail, suggests that a clearer understanding of the events leading to "Megxit" has emerged, with Thomas Markle at the forefront. This perspective positions his actions as a primary catalyst for the couple's decision to leave Britain and relinquish their senior royal status.

The statement released by the couple at the time indicated a desire for a new path, marked by financial independence and a continued, albeit modified, commitment to the monarchy. The events surrounding their departure have been a subject of intense public and media scrutiny since their announcement.
