‘This short case involves the old dilemma of public order law: whether it is right to shut down speech when the speaker himself does not intend to incite violence, but whose presence it is said may lead third parties to commit violence. Indeed the facts of this particular case go further than that , because the applicants had no plans to make any public address during their proposed visit to Britain. It was their presence alone which was feared would inflame “community tensions”.’
