Schillings, the law firm, described the publication as part of a “campaign by this media group to publish false and deliberately derogatory stories about her, as well as her husband, Prince Harry… We have issued proceedings to redress this breach of privacy, infringement of copyright and the aforementioned media agenda.”
A spokesman for the Mail on Sunday was not immediately available for comment on the claim.
In a lengthy statement released alongside the announcement of legal action, Prince Harry said his wife had “become one of the latest victims of a British tabloid press that wages campaigns against individuals with no thought to the consequences.”
Prince Harry and Meghan have been touring southern Africa together with their baby son, Archie.
