The next parliamentary elections in Lithuania are expected to be held on 8 October 2028, with a second round two weeks thereafter.[1]
See main article: Elections in Lithuania.
The Seimas has 141 members, elected to a four-year term in parallel voting, with 71 members elected in single-seat constituencies using the two-round system and 70 members elected by proportional representation.[2] The voting in the elections is open to all citizens of Lithuania who are at least 18 years old.
Parliament members in the 71 single-seat constituencies are elected in a majority vote, with a run-off held within 15 days, if necessary. The remaining 70 seats are allocated to the participating political parties using the largest remainder method. Parties normally need to receive at least 5% (7% for multi-party electoral lists) of the votes to be eligible for a seat. Candidates take the seats allocated to their parties based on the preference lists submitted before the election and adjusted by preference votes given by the voters.
Parliamentary election poll results are listed in the table below in reverse chronological order. The highest percentage figure in each poll is displayed in bold, and its background is shaded in the leading party's colour. The "Lead" column shows the percentage point difference between the two parties with the highest figures.
