Tremaglia. These parliamentary seats are organised into four constituencies (Europe, North & Central America, Latin America, and Africa/Asia/Oceania). Candidates must live in their respective constituencies. Forty-two percent of eligible voters abroad participated in the elections. Prodi's The Union managed to secure 4 of the 6 Senate seats, while Berlusconi's Forza Italia and an Independent candidate each gained 1 of the remaining 2 seats, aiding Prodi in gaining a majority in the Italian Senate. In the House of Deputies, 7 seats went to The Union, 4 to Berlusconi's coalition, and one to an Independent candidate. In North America, candidates from Toronto and Chicago were elected to the House of Deputies while the candidate from New York City was elected to the Senate.

Until 2001 the Italian Republic offered citizens living abroad a free return train journey to their home town in Italy in order to vote, however the portion of the train journey that was free of charge was only on Italian soil. Any costs incurred in getting from their place of residence abroad to the Italian border had to be covered by the citizen wanting to vote, therefore a free return train journey was hardly an incentive for the large Italian communities living as far away as in the United States, Argentina or Australia. For this reason very few Italians abroad
