2018 Czech Senate election

Senate elections were held in the Czech Republic on 5 and 6 October 2018 alongside municipal elections, with a second round held on 12 and 13 October 2018. The Conservative Civic Democratic Party (ODS) won the election with 10 seats. Governing parties ANO 2011 and the Czech Social Democratic Party were heavily defeated, winning only 1 seat each. The Communist Party lost its last seat in the Senate when Václav Homolka failed to be re-elected, meaning the party would be without representation in the Senate for the first time in the history of Czech Republic. The election was considered the first major win for the opposition to Andrej Babiš' Cabinet. Commentators including Josef Kopecký also noted ODS confirmed their position as the main opposition party, ahead of the Czech Pirate Party.
