At a preliminary hearing in London on Thursday, Mr Justice Nicklin will be asked to determine the "natural and ordinary" meaning of parts of the article addressed in the claim. He will also consider whether they are statements of fact or opinion and whether they are defamatory.

His judgement is expected to be revealed in writing at a later date.
Barrister Justin Rushbrooke QC, who is leading Harry's legal team, told the judge, in a written case outline, that Harry had brought the claim following a website article and an article in the Mail on Sunday in February.

He argued both articles were "defamatory" and meant that Harry had "lied", had "improperly and cynically" tried to manipulate public opinion, and had "tried to keep his legal fight with the Government secret from the public".

Mr Rushbrooke said Associated Newspapers disputed that the words complained or bore "any meaning defamatory" of Harry.
Harry is bringing a separate claim against the Home Office after being told he would no longer be given the "same degree" of personal protective security when visiting from the US, despite offering to pay for it himself.
