Italy’s Prime Minister Giorgia Meloni faced a significant parliamentary setback after a narrowly defeated electoral reform proposal, raising questions about the stability of her governing coalition. The reform, which was put forward by Meloni’s Brothers of Italy party, aimed to overhaul the country’s voting system by introducing a fully proportional representation model with bonus seats awarded to any coalition securing more than 42% of the vote. This change was intended to enhance government stability by favoring larger alliances formed before elections.

On Tuesday, the lower house of Parliament voted on the measure, resulting in a tie of 187 votes in favor and 187 against during a secret ballot. The outcome was attributed to rebellion within Meloni’s coalition: while Brothers of Italy maintained unity behind the proposal, several members from coalition partners the League and Forza Italia withheld their support. These defections undermined the reform, effectively blocking the Prime Minister’s plans.

Under the existing mixed electoral system, roughly one-third of seats are allocated via first-past-the-post constituencies, with the remainder distributed proportionally according to party lists managed by leadership. Meloni’s initiative would have abolished the current method, which critics say favors the center-left bloc, and replaced it with a system that continued to grant parties significant influence over candidate selection while rewarding well-organized pre-election coalitions—an advantage to her conservative alliance.

Opposition parties interpreted the defeat as evidence of weakened control over the parliamentary majority and urged Meloni to resign. In response, Meloni acknowledged the loss as a “call for reflection” and lamented that “the swamp won again,” referencing entrenched political opposition. Despite the setback, her coalition allies, including Forza Italia’s parliamentary leader Enrico Costa, emphasized the importance of continuing to pursue electoral reform to ensure government stability.

This episode follows other recent challenges for Meloni, notably the March rejection of her judicial reform proposals in a public referendum. Nonetheless, Meloni is poised in September to become Italy’s longest-serving prime minister since World War II, and her party remains the most popular individual political force in the country, according to recent polls. However, these same polls indicate that her coalition is trailing a potential alliance between the center-left Democratic Party and the anti-establishment Five Star Movement.

The failure to pass the electoral reform adds uncertainty ahead of next year’s general elections, with political analysts warning it could contribute to a fragmented parliament lacking a clear governing majority. Meloni’s reform drive aimed to prevent such an outcome by incentivizing pre-election alliances, but divisions within her coalition highlight ongoing challenges to that goal.
