For the first time in the history of the French republic, a serving minister of justice has been placed under formal investigation by examining magistrates. On Friday July 16th Éric Dupond-Moretti was told he faces a judicial probe by the Cour de Justice de la République (CJR) – which handles allegations relating to a minister's official functions - over claims of an unlawful conflict of interest between his position as justice minister under President Emmanuel Macron and his previous role as a high-profile lawyer. In particular Dupond-Moretti is suspected of using his ministerial post to settle scores with prosecutors and a judge with whom he clashed when working as a lawyer. Lawyers acting for Dupond-Moretti, who denies any wrongdoing, say he intends to stay in his position despite the judicial investigation. Fabrice Arfi reports.
