The Mail on Sunday published the letter on 10th February, in a four-page article written by Caroline Graham. Thomas Markle—who supplied it to the newspaper—has legal ownership of the letter as its recipient, though copyright is retained solely by his daughter, as its writer. Thus, the newspaper was not legally entitled to reproduce it.
The Queen sued another UK tabloid, The Sun, for breach of copyright in 1992, after it published a transcript of her Christmas broadcast two days early. More recently, Prince William and his wife Kate Middleton, the Duchess of Cambridge, sued the French magazine Closer for invasion of privacy.
