Meghan Markle apologises for forgetting she briefed biography authors

However, the Court heard on Tuesday that Meghan had asked an aide, Jason Knauf, to brief the authors.

Mr. Knauf said the book was "discussed on a routine basis" and "discussed directly with the Duchess multiple times in person and over email".

In a formal apology, Meghan said she had forgotten the events.

The Duchess sued Associated Newspapers Limited (ANL), the publisher of the Mail On Sunday, earlier this year over five articles that included parts of a "personal and private" letter sent to her father. The High Court ruled that ANL's publication of the letter was clearly unlawful and there was no need for a trial. But now, ANL is appealing the ruling, as lawyers for the publication claim the letter was written knowing that it may be made public. Lawyers quoted text messages from The Duchess to Mr. Knauf where the letter was discussed, in which she said: "Obviously everything I have drafted is with the understanding that it could be leaked, so I have been meticulous in my word choice."

In a witness statement to the court, Meghan accepted that her aide had provided information to the authors with her knowledge. However, she added she was unclear about the extent of the information.

"When I approved the passage... I did not have the benefit of seeing these emails and I apologise to the court for the fact that I had not remembered these exchanges at the time," she said.

"I had absolutely no wish or intention to mislead the defendant or the court."
