The Duke and Duchess of Sussex could be questioned as part of a US defamation case brought by Meghan’s half-sister.
Samantha Markle is suing Meghan for “defamation and injurious falsehoods” following the couple’s interview with Oprah Winfrey in 2021.
She alleges she was defamed when Meghan “falsely and maliciously” said she was “an only child”.
A motion brought by Meghan to stop depositions in the civil case from taking place was dismissed by a judge.
A deposition is a formal statement of evidence in the US, required to be given by a witness or a party involved in a legal case.
In the high-profile interview with Oprah Winfrey, the couple discussed their families, royal life and mental health.
The duchess’ half-sister claimed, in a filing submitted in March 2022, that Meghan made “demonstrably false and malicious statements” to a worldwide audience.
Documents obtained by PA News agency show the original motion.
They show Samantha Markle, who has MS and uses a wheelchair, brought the action, saying around 50 million people in 17 countries had watched the Winfrey interview.
The motion says that it “disseminated false and malicious lies” and had subjected Samantha Markle to “humiliation, shame and hatred on a worldwide scale”.
