Thomas Markle could appear in court to testify against his daughter as part of the defence in a legal battle launched by the duchess over privacy.
Meghan launched a legal battle against the Mail on Sunday and its parent company Associated Newspapers in October, accusing it of unlawfully publishing a personal letter she sent to her father.
The paper will argue that the publication was justified because there is a “huge and legitimate” public interest in the “personal relationships” of members of the Royal Family.
Legal documents show that the defence argument will rely on evidence from Mr Markle to make its case.
If the case goes to trial, the duchess and her father could be called upon to testify against one another – the paper’s sister publication the Daily Mail has claimed Mr Markle would be prepared to do so.
Law firm Schillings, representing the duchess, has alleged the misuse of private information, infringement of copyright and a breach of the Data Protection Act 2018.
However, the paper will claim Mr Markle “had a weighty right to tell his version of what had happened between himself and his daughter including the contents of the letter”.
It also argues the duchess “did not have a reasonable expectation of privacy that the contents of the letter were private and would remain so”.
The news comes after a tumultuous week for Meghan and Prince Harry, who last Wednesday announced that they wished to step back as senior royals.
This week the Queen issued a statement saying that although the Royal Family “would have preferred” that the couple continued in their roles, they were “entirely supportive of Harry and Meghan’s desire to create a new life as a young family”.
