The Brothers of Italy party stands out from the crowd and is expected to gain the largest share of the vote for a single party.
Giorgia Meloni, leader of the right-wing party Fratelli d'Italia (Brothers of Italy) holds a giant Italian national flag during a political rally on February 24, 2018 in Milan, Italy.
The snap election follows the resignation of Prime Minister Mario Draghi in July, after he failed to unite a fractious political coalition behind his economic policies.
An election win by Fratelli d'Italia could see the party's leader, Giorgia Meloni, become Italy's first female prime minister.
Fratelli d'Italia has been pro-NATO and pro-Ukraine and supports sanctions against Russia, unlike Lega which is ambivalent about those measures.
