Election Poll Czech Republic: Results from STEM on June 27, 2026

According to STEM, 6 parties are projected to surpass the electoral threshold and enter the Czech Republic's Chamber of Deputies: ANO 2011 with 81 representatives, STAN with 34 representatives, ODS with 33 representatives, SPD with 20 representatives, Piráti with 19 representatives and Motoristé with 13 representatives.

The Czech Chamber of Deputies (Poslanecká sněmovna) comprises 200 members elected for a four-year term under a system of proportional representation. The country is divided into 14 electoral districts, corresponding to its regions (Kraje). Voters cast their ballots for a party list but can also support individual candidates with up to four preferential votes. Should a candidate secure enough preferential votes, they advance on the list, granting voters direct influence over the parliament's composition.

To enter the Chamber of Deputies, individual parties in the Czech Republic must clear a 5% national electoral threshold. The hurdle rises for electoral alliances: two-party coalitions require 7%, while alliances of three or more parties need 11%. This rule aims to boost parliamentary stability and prevent excessive fragmentation by smaller fringe parties. Parties failing to meet this threshold secure no seats in the D'Hondt method of seat allocation.

Government formation in the Czech Republic typically begins with the President tasking the leader of the strongest party or a successful electoral alliance. As the electoral system rarely grants any single party an absolute majority, coalition governments are the norm. A new government must face a vote of confidence in the Chamber of Deputies within 30 days of its appointment. Political stability often hinges on internal coalition discipline, as the parliament can unseat the government through a vote of no confidence.
