TODAY the Duchess of Sussex’s lawyers are up against Associated Newspapers Ltd as it seeks to limit her lawsuit against them by having sections of it struck out.

In particular it wants claims it acted dishonesty and with malice when the Mail on Sunday published a letter she sent her father to be removed from her pleadings.

The Mail on Sunday is the UK’s biggest mid-market Sunday newspaper and sister to The Daily Mail and MailOnline, which is among the world’s best-read news and gossip websites. Its owner is the billionaire Press oligarch Viscount Rothermere.

The procedural hearing in front of Mr Justice Warby at the High Court in London is due to start at 10:30am BST and last all day. No witnesses will be called, with evidence filed in written form.

However, key details of the Duchess’s case will be emerging - as will the Defence of the newspaper publishers.

Byline Investigates will be covering the proceedings with live Tweets and other rolling coverage.
