Under the influence of several investigations
Shortly after his arrival at town hall in March under the UDR-RN banner, after three mandates of Mr. Estrosi, Mr. Ciotti ordered his rival to provide supporting documents, before sending a report to the public prosecutor's office. Mr. Estrosi's lawyer did not react immediately but when questioned last year about his representation fees, the former mayor assured that they were exclusively meals with investors, personalities from the world of economy or culture, to advance the issues of the city and the metropolis.
Mr. Estrosi is already the subject of several investigations, even if he has not been indicted. The management of the reconstruction after storm Alex in 2020 is called into question, and he has the status of assisted witness in the investigation into the security of the Promenade des Anglais on the evening of the ram truck attack which left 86 dead on July 14, 2016.
He was also placed in police custody at the start of the summer of 2025 in an investigation into the organization of several events in Nice and the management of the Formula 1 GPs in Castellet (Var) between 2018 and 2022, of which he chaired the Public Interest Group. The former mayor of Nice is the subject of an investigation for favoritism and embezzlement.
