Yet, O Mail on Sunday he claimed that he “had not maintained contact by phone, letter or e-mail” with the Royal Marines since then.

The judicial process, seen by Newsweek, reads: “[Prince Harry’s] The sincere ambition is to continue to help current and former military personnel using their reputation and the platform they have as a result of their military service.
“This role depends substantially on [Prince Harry] using their reputation to help these causes, attracting public support for them.
“Publishing the complaints that they complain about will seriously impair their ability to do so and will therefore have an adverse effect on the people he seeks to help.
“[Prince Harry] In particular, he used his reputation to support and encourage current and former military personnel to seek help for mental health problems.
“The publications claimed will decrease [Prince Harry’s] credibility in the eyes of such staff and therefore make them less likely to seek the help that is being offered.

“This was manifestly unfair and violated the most basic journalistic standards.
“He showed total contempt for [Prince Harry’s] reputation, for its version of events and, therefore, for justice and truth. “
The court case says the allegations were presented as “highly credible”, as they cited “informed sources” that could “mean only Royal senior officers.
Marines.”
