[97] “The truth is that the law in the United Kingdom has come only slowly and reluctantly towards regarding freedom of speech as a right worthy of protection. UK law has been pulled there in large measure under the influence of the ECHR [which has] done more than any other source to help the common law see that freedom of speech merits at least a degree of legal protection.” Tomkins, On the Law of Speaking Freely, 102.
