Luigi de Magistris (born 20 June 1967) is an Italian politician and a former prosecutor, currently the mayor of Naples. He started his career as a public prosecutor in 1995 and worked in Naples from 1998 to 2002. He was deputy public prosecutor in Catanzaro from 2002 to 2009 and was a Member of the European Parliament (MEP). His investigations have frequently focused on links between politicians and the Mafia.
In 2011, de Magistris ran for the Mayor of Naples as the candidate of Italy of Values. He won in the second round, defeating the right-wing candidate Gianni Lettieri with 65% of the vote.
As his investigations involved famous names such as Romano Prodi, former Italian prime Minister, and Clemente Mastella, former Italian Minister of Justice, de Magistris has been at the centre of media controversy. The Minister of Justice Clemente Mastella asked de Magistris to be transferred because he had allegedly revealed Mastella's name as well as those of other Italian politicians apparently involved in his investigations. De Magistris appeared before the CSM (the governing board of the magistracy) in January 2008 to defend himself against the serious allegations of the Minister and his inspectors.
Luigi de Magistris has been the second most voted Italian politician in 2009 European elections.
In 2017 he obtained the 'Valerioti-Impastato' award for his work against crime and corruption.
While in Catanzaro, he worked for several years on the "Poseidone" investigation into misuse by politicians of European Community subsidies for sewage filter systems and other business projects in Calabria. The "Poseidone" case was taken away from Luigi de Magistris, and as was the "Why Not" investigation in which the names of well-known politicians have come up. This investigation was due to be wound up after nearly two years and the persons involved formally indicted. Another case that de Magistris has been involved with is "Le Toghe Lucane", in Basilicata. One of the people to be questioned by de Magistris was Henry John Woodcock, a public prosecutor in Basilicata.
The European Anti-Fraud Office (OLAF) started the enquiry and handed it over to Luigi de Magistris in May 2005. Investigations started in May 2005 into an allegedly illegal use of 200 million € of European Community funds. Luigi de Magistris has been removed from the investigation with the accusation that de Magistris did not keep the details of the case confidential and revealed the names of people under investigation, including Forza Italia senator Giancarlo Pittelli and general Walter Lombardo Cretella.
This investigation is about illegal use of public funding. The name of the former Italian Minister of Justice Clemente Mastella appears in the investigation, thanks to his contacts with Antonio Saladino, a key figure in the enquiry.
