The historical basis was the Marconi Affair, a political scandal in which a number of government ministers made money speculating in the stock of the American Marconi company, apparently taking advantage of inside information that the British Marconi Company was to be awarded a government contract to build a chain of wireless stations. Cecil Chesterton wrote a series of vituperative articles attacking several of the principal figures, was sued for criminal libel, conducted his own defense (incompetently) in the belief that the ability to argue was an adequate substitute for knowledge of the law, was convicted and briefly jailed. Three of his opponents in the case, Godfrey Isaacs, a director of both the British and American Marconi Companies, his brother Sir Rufus Isaacs (later the Marquis of Reading), then Attorney General, and Herbert Samuel, the Postmaster General, were Jewish.
