Finland: Opinion poll by Taloustutkimus on 09/30/2025

The Finnish Parliament (Eduskunta) consists of 200 members elected for a four-year term. The country is divided into 13 electoral districts. Finland uses a proportional representation system with open lists: voters must cast their ballot for a specific candidate rather than just a party. The total number of votes for all candidates in a party determines how many seats that party receives, while the individual vote counts determine which specific candidates are elected. A special provision exists for the Åland Islands, which are guaranteed one permanent seat in the parliament.

Unlike many other European nations, Finland does not have a legally mandated national percentage threshold (such as a 5% rule) to enter parliament. Instead, the hurdle for a party to win a seat is determined by the "natural quorum" within each specific electoral district. In larger districts like Helsinki, it is easier for smaller parties to secure a mandate than in smaller districts with fewer seats. This system encourages a diverse and multi-party parliamentary landscape.

Since no single party in Finland typically wins an absolute majority, coalition governments are the norm. These coalitions often include four or more parties to ensure a stable majority in the Eduskunta. Following an election, the leader of the largest party initiates negotiations to form a government. A hallmark of Finnish politics is the highly detailed Government Programme, which serves as a binding roadmap for the coalition’s four-year term. The government must be formally approved by parliament through the election of the Prime Minister.

This overview shows all parties that, based on current polling, have a realistic chance of entering parliament in Finland or significantly shape the political debate. Classifying their political orientation is essential for understanding bloc formation and the mathematically possible majorities in the next parliament.
