The Italian Parliament voted on Tuesday to back Rome's bid to host the 2024 Olympic Games.
Italian Premier Matteo Renzi is a strong supporter of Rome's candidacy and the Parliament has now thrown its weight behind the bid.
"Today the Italian Parliament adopted, by a large majority, a clear and indisputable position on the candidature of Rome to the Olympic Games of 2024," read a statement on the bid website.
"It is a strong yes, an expression of the popular will, which blows away controversies and gives to the city and the country an important opportunity for economic redemption and the revival of international image."
The IOC will select the 2024 host city next year.
Los Angeles, Paris and Budapest, Hungary, are the other bidders.
Rome last hosted the Olympics in 1960. It lost out to Athens in the final voting round for the 2004 Games and was forced to withdraw its bid for the 2020 Olympics after the government of then Premier Mario Monti declined to provide financial backing.
