After earning a law degree and a degree in literature, Pujo trained at the Institut technique de banque (ITB) and embarked on a banking career, working for eleven years at Crédit Lyonnais.[4]
Pujo served as the president of the Action française's steering committee and as the director of the biweekly royalist, nationalist, and sovereigntist journal L'Action française 2000 (formerly L'Action française hebdo), which was affiliated with the Centre royaliste d'Action française. He authored several works chronicling the history of the Action française movement, co-founded by his father, Maurice Pujo, alongside Henri Vaugeois and Charles Maurras. A firm believer in the royalist tradition originating with the Capetians, he supported the legitimacy of the House of Orléans.
Occasionally, Pujo wrote under the pseudonym "Jacques Cépoy",[5] particularly when penning editorials for L'Action française 2000.
Key moments in his career included opposition to Algerian independence and his successful efforts to retain the island of Mayotte within the French national community in 1976.[6] Later, he critically observed the rise of the National Front.
In 2002, Pujo endorsed Jean-Pierre Chevènement in the first round of the presidential election, attracted by Chevènement’s traditional and patriotic approach to politics.[7] In 2007, he supported Jean-Marie Le Pen due to Le Pen’s opposition to the Lisbon Treaty,[8] though he expressed reservations about Le Pen, particularly regarding the commemoration of the Battle of Valmy by the National Front in September 2006.[9]
He had a sister, Marielle Pujo.
