Satirist William Hone is the forgotten hero of the British press. In 1817 he was forced to defend himself against a censorious government, in what amounted to a show trial pitting a self-educated Fleet Street journalist against the Lord Chief Justice and a hand-picked jury. Hone's crime was to ridicule the powers that be. Through Hone's life, Ben Wilson looks at the history of the struggle for free expression against repressive law.
