Vine's lawyer, Gervase De Wilde KC, said: "I don't propose to open the case, but Mr Barton has been publicising this case inaccurately on his X account. Could we make clear this is a defamation and harassment case over publications by Mr Barton which have reached millions of readers, which said he had a sexual interest in children.
"Mr Barton's publications were made on X, branding Mr Vine a "nonce" and, in a number of instances, adding colour to this allegation by comparing Mr Vine to high profile predatory celebrity paedophiles and suggesting that the police should be contacted about his proximity to children.
"Mr Vine contends that the publication of this term, and related words and images, bears a seriously defamatory meaning of him, to the effect that he has a sexual interest in children."
