Meghan Markle has demanded the Mail on Sunday pay her $2.7 million in legal fees and hand over copies of her letter to her estranged father.
Last month a High Court judge ruled that the publisher had breached Meghan's privacy after printing parts of the letter she wrote to Thomas Markle, reports the Sun.
In a virtual hearing this week, Meghan's lawyers asked the High Court to order Associated Newspapers to hand over any copies of the letter and destroy any electronic copies made, as well as any notes made about it.
Meghan also said her legal costs were around $2.7m, and demanded 50 per cent to be paid within the next two weeks.
Lord Justice Warby ordered the Mail on Sunday to pay her $800,000 in costs, with more to be paid in future.
