Diego Novelli (born 22 May 1931) is an Italian politician. He is a former mayor of Turin.
A member of the city council of Turin since 1960, Novelli was elected Mayor of Turin in 1975 with the support of the Italian Communist Party (PCI) and the Italian Socialist Party (PSI), and remained in office for 10 years, during the difficult Years of Lead. Novelli was a member of the European Parliament from 1984 to 1987,[1] when he was elected to the Chamber of Deputies. He remained a member until 2001. With the svolta della Bolognina and the end of the PCI, he co-founded with Leoluca Orlando the left-wing party The Network (LR) and tried to be re-elected mayor of Turin in 1993, supported by LR and the Communist Refoundation Party. Although he was ahead on the first round, he was defeated on the second ballot by the centre-left candidate Valentino Castellani.[2] In 2009, Novelli stood in the 2009 European Parliament election in Italy with Left Ecology and Freedom but failed to be elected. In 2011, he was elected president of the provincial committee of ANPI.[3]
