The other major feature was the sudden rise of the federalist Northern League, which increased its vote from 0.5% of the preceding elections to more than 8%, increasing from a single member both in the Chamber and the Senate to 55 and 25, respectively. The "long wave" ("onda lunga") of Bettino Craxi's now centrist-oriented Italian Socialist Party, which in the past elections had been forecast next to overcome PCI, seemed to stop. Christian Democracy and the other traditional government parties, with the exception of the Republicans and the Liberals, also experienced a slight decrease in their vote.
