Pietro Badoglio
On 24 and 25 July 1943, De Bono was one of the members of the Fascist Grand Council who voted to oust Benito Mussolini when Dino Grandi, in collaboration with Pietro Badoglio and King Victor Emmanuel III, put a nonconfidence motion to the vote of the Grand Council of Fascism. That led to the dictator's downfall, arrest and imprisonment.
