Sweden: Opinion poll by Verian on 12/07/2025

The Swedish Parliament, the Riksdag, consists of 349 members elected every four years. The electoral system is based on proportional representation, with 310 fixed seats allocated across 29 constituencies. To ensure that the overall distribution of seats accurately reflects the national popular vote, the remaining 39 seats are distributed as leveling seats (utjämningsmandat). This system guarantees high proportionality, ensuring that almost every vote cast across the country has a direct impact on the final composition of the Riksdag.

To enter the Swedish Riksdag, a political party must typically clear a national electoral threshold of 4%. However, there is a specific exception: if a party manages to secure at least 12% of the vote within a single constituency, it can win a seat in that district even if it falls below the 4% mark nationwide. In Swedish political life, the 4% threshold is often a critical "make-or-break" point, as the failure of a smaller coalition partner to cross it can drastically shift the balance of power between the major political blocs.

Sweden operates under the principle of "negative parliamentarism." A candidate for Prime Minister (Statsminister) is confirmed as long as a majority of the Riksdag (at least 175 members) does not vote against them. An absolute majority of "yes" votes is not required. This often leads to the formation of minority governments, which are very common in Sweden. These administrations rely on formal or informal agreements with support parties to pass budgets and legislation, fostering a political culture rooted in negotiation and consensus-building.

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