They have lost round one.
The Mail on Sunday has won the first round of a legal battle against the Duchess of Sussex over the publication of a letter she wrote to her father.
The duchess is suing for breach of privacy and copyright infringement after articles reproduced parts of a letter she sent Thomas Markle.
The publisher denies the allegations.
On Friday it won its bid to have parts of Meghan's claim struck out. Her lawyers said the ruling did not change "the core elements of this case".
What happened at the ruling?
At a hearing held remotely last week, Associated Newspapers - the publishers of the Mail on Sunday, Daily Mail and MailOnline - asked for parts of Meghan's case to be dismissed.
Judge Mr Justice Warby agreed and on Friday struck out parts of Meghan's claim, including her allegations the publisher acted "dishonestly" by leaving out certain parts of the letter.
He also dismissed Meghan's allegations that the publisher deliberately "dug up" issues between Meghan and her father, and that it had an "agenda" of publishing intrusive or offensive stories about her.
Mr Justice Warby said the allegations he struck out do not go to the "heart of the case", and that they may be brought back at a later stage if they are put on a proper legal basis
