The former Socialist deputy
Tito Zaniboni was arrested for attempting to assassinate Mussolini on November 4, 1925. In a hotel with a view onto
Palazzo Chigi, where Mussolini had planned to give a balcony speech, Zaniboni set up a rifle with telescopic sights. Shortly before his target appeared, however, Zaniboni was arrested. A friend and double agent had informed the police. Historians believe that the plot itself was engineered by the Mussolini administration as a pretext to consolidate power, which is what followed. Mussolini's laws enacted in late 1925 enabled the suppression of any oppositional political organization. The
Italian army officer
Luigi Capello was arrested in conjunction with the Zaniboni plot and received a 30-year prison sentence. The author and labor organizer
Carlo Tresca wrote a play and political satire in late 1925 based on the attempt, ''L'Attentato a Mussolini ovvero il segreto di Pulcinella
(The Attempt on Mussolini or the Secret of Pulcinella''). Zaniboni received a 30-year prison sentence, but was released in 1943 after the King dismissed Mussolini as prime minister, and was later named to government positions. ==Violet Gibson==
