The subject matter is a defamation lawsuit brought by a television presenter against a political blogger concerning an article about online disputes related to the antisemitism debate within the Labour Party. The core of the case concerns the allegation that the claimant conducted a campaign of harassment against a minor and incited her followers to issue death threats. The court ruled to strike out the defendant’s principal defence submissions on the grounds that they had no realistic prospect of proving the truth of the defamatory statements of fact - Defamation Act 2013 (sections 2, 3, 4), Protection from Harassment Act 1997, Article 10 ECHR.
