Italian regions were united in 5 constituencies, each electing a group of deputies.

At national level, seats were divided between party lists using the largest remainder method with Hare quota.

All seats gained by each party were automatically distributed to their local open lists and their most voted candidates.

The new party Forza Italia (FI), led by the Italian Prime Minister Silvio Berlusconi, won the election with 30.6% of the vote and 27 seats.

The Italian People's Party (PPI), main heir of Christian Democracy (DC), gained only 10.0% of the vote and 8 seats.
