General elections were held in Italy on June 14, 1987. This election marked the final inversion of the trend of the entire republican history of Italy: for the first time, the distance between the Christian Democrats and the Communists grew significantly instead of decreasing, and this fact was seen as the result of the deindustrialization of the country. The growth of the service sector of the economy, and the leadership of former PM Bettino Craxi, gave instead a new strength to the Socialists. A remarkable novelty was the rise of the new Green Lists, while a new party obtained its first two parliamentary seats: the North League.
For the Senate, 237 single-seat constituencies were established, even if the assembly had risen to 315 members. The candidates needed a landslide victory of two thirds of votes to be elected, a goal which could be reached only by the German minorities in South Tirol. All remained votes and seats were grouped in party lists and regional constituencies, where a D'Hondt method was used: inside the lists, candidates with the best percentages were elected.
