Czech Republic runoff 2026: Senate (one third), second round

Final count

Turnout 21.1%: 475,476 ballots from 2,252,325 registered voters.

RUNOFF ONLY: the 22 districts with a second round on 16–17 Oct 2026 and the 22 seats won there, as declared by notice No. 194/2026 Sb., part II; the 5 seats won outright on 10 Oct and the whole renewal (27 seats) are in czech-republic-senate-2026. Method: the SVK notice gives national totals and the elected senators with their nominating party, but no votes by party, so the party vote totals are OUR SUMS of the ČSÚ's official per-district candidate results (volby.gov.cz/appdata/senat/20261009/vysled/obvod/<n>.json for the 27 districts, read 25 Oct 2026), grouped by nominating party (navrhující strana: the party itself, or for a coalition the party the notice names as 'Navrhující politická strana'; 'Nezávislý kandidát' groups the independents who stood on a petition); names from the ČSÚ's party register (cisel/cpp.json). Our sums add up exactly to the notice's valid-vote totals. Only the 13 nominating parties with a runoff finalist are listed, by second-round votes. Seats won in round two: STAROSTOVÉ A NEZÁVISLÍ 7, Občanská demokratická strana 7, KDU-ČSL 2, and one each for TOP 09, SEN 21, Starostové pro Liberecký kraj, Naše Město F-M, 24/7 and Osobnosti pro kraj = 22. winner marks the most second-round votes (STAROSTOVÉ A NEZÁVISLÍ, level on seats with ODS). Totals from the notice, part II: registered 2,252,325; envelopes issued 475,714; envelopes cast 475,476 (= ballots); valid votes 473,245 (= totalVotes); turnout 21.12%.
