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 election was won again by Forza Italia, just accepted to the European People's Party, that got 25.2% of the vote and 22 seats.

Instead a good result was obtained by Bonino List, that gained 8.5% of the vote and 7 seats.
