Associated Newspapers Limited on Tuesday began an appeal against a ruling that its publication of parts of the letter to Thomas Markle breached her privacy.
Jason Knauf, who was communications secretary to Meghan and her husband Prince Harry until March 2019, said in a statement to the Court of Appeal in London the duchess had told him that she had known it was possible that her father would release the letter.
She said she had 'toiled over every detail which could be manipulated'.
