Leonilde Iotti, commonly known as Nilde Iotti (April 10, 1920 - December 4, 1999) was an Italian politician, the first woman to became president of the Italian Chamber of Deputies for three consecutive legislatures from 1979 to 1992.
In April 1948 Iotti was elected for the Italian Communist Party (PCI) to the Chamber of Deputies, of which she was member without interruptions until 1999. Iotti had a long liaison with the National Secretary of the PCI Palmiro Togliatti, one which lasted until the latter's death in 1964: the relationship was made public in 1948, on the occasion of the attempt on Togliatti's life, a few days after the Italian general election day, and was received coldly by Italy's public opinion, including many Italian communists, because Togliatti was married to Maria Montagnana at the time.
In 1979, Iotti became Speaker of the Lower House of Parliament, succeeding to Pietro Ingrao. She was popular and respected as a president, and was confirmed in the office for two more legislatures. In 1987, she was entrusted by President Francesco Cossiga with a mandate of potentially forming the government, the closest a PCI member, and a woman, got to becoming Prime Minister of Italy; however, Iotti was not able to form a coalition.
She died in Rome.
