Meghan Markle has said her British friends warned her against marrying Prince Harry, telling her the UK tabloids “will destroy your life”.

The Duchess of Sussex made the revelation in an ITV documentary, filmed while the couple were on an official visit to southern Africa earlier this month, which aired last night.

While on tour, Markle filed a lawsuit against the Mail on Sunday over its publication of a private letter she had sent to her estranged father. The paper has said it will “vigorously” defend the case.
