Slovenia: Opinion poll by Mediana on 11/13/2025

The Slovenian National Assembly (Državni zbor) consists of 90 members elected for a four-year term. The system uses a two-tier proportional representation model: 88 seats are distributed across eight constituencies, each divided into eleven voting districts. Voters cast their ballot for a specific candidate in their district, which also counts as a vote for that candidate's party. Seats are first allocated at the constituency level using the Droop quota and then at the national level using the D'Hondt method to ensure overall proportionality. Two seats are specifically reserved for the Italian and Hungarian national minorities, elected using the Borda count (a positional voting system).

To enter the National Assembly, political parties must clear a nationwide electoral threshold of 4%. This requirement is designed to ensure legislative stability and prevent excessive fragmentation within the parliament. Only parties reaching this 4% mark qualify for the allocation of the 88 proportional seats. The two representatives for the national minority communities are exempt from this threshold, as they are elected through separate, dedicated voting procedures within their respective communities.

Slovenia's multi-party system makes coalition governments the standard, as it is rare for a single party to win an outright majority. Following an election, the President of the Republic proposes a candidate for Prime Minister to the National Assembly. The election is conducted by secret ballot and requires an absolute majority (46 out of 90 votes). Slovenian politics is frequently characterized by the rapid rise of "new faces"—parties formed shortly before elections that often secure significant mandates and lead coalition negotiations, contributing to a dynamic political environment.

This overview shows all parties that, based on current polling, have a realistic chance of entering parliament in Slovenia 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.
