Pre-campaign period and cooperation agreements Super-debate in the
National Museum in Prague On 8 February 2023, Babiš announced he would limit his role within ANO. He would remain as an MP and the leader of the party, while
Karel Havlíček and
Alena Schillerová would become the primary faces of the party, with Havlíček becoming leader of the
shadow cabinet. Babiš described Havlíček as a future prime minister of the Czech Republic. On 21 March 2025,
SPD,
Svobodní,
Tricolour and
PRO signed a memorandum agreeing to cooperate in the 2025 parliamentary election on the SPD candidate list. In July, PRO threatened to leave the joint list, citing insufficient representation of its candidates on the electoral lists, and floated the idea of joining Stačilo! instead. They later decided to remain on the SPD list. It was subsequently confirmed that each of the smaller parties had only two candidates across all the regional lists (albeit all in the top three candidates in their respective regions), with the rest of the places taken by SPD candidates. Svobodní voiced their disappointment at this arrangement, claiming that "there was not enough time to put together fairer lists", but that "the basic goals are met".
Stačilo! announced its regional leaders in March 2025 at a press conference in
Ostrava. The national leader was designated as MEP and
KSČM leader
Kateřina Konečná, who stated that she would resign her seat in the
European Parliament if elected to the
Chamber of Deputies. In the
Central Bohemian Region, the list was led by former MEP
Jana Bobošíková, in the
South Moravian Region by blogger
Daniel Sterzik, in the
Pardubice Region by Roman Roun, and in the
Liberec Region by former
Communist Party MP . On 23 June, the
Pirates and the
Greens announced that 30 Green candidates would be included on Pirate Party candidate lists in eight regions, with the Greens' co-leader running in
Prague. On 17 July,
Stačilo! and
SOCDEM reached an agreement which would see the Social Democrats endorsing the coalition's manifesto and their candidates running on the Stačilo! list.
Jana Maláčová led the list in
Prague, Jiří Nedvěd in the
Karlovy Vary Region, and
Lubomír Zaorálek took the second spot on the list in the
Moravian-Silesian Region. Under the agreement, SOCDEM would be represented by two candidates on each regional list. This decision triggered a backlash from SOCDEM figures and members, with a substantial drop in membership reportedly linked to the agreement.
Lawsuits against non-coalitions Volt argued that SPD and Stačilo!'s non-coalitions circumvented the higher threshold in place for coalitions, and prepared to file a lawsuit. They later confirmed that they would bring 28 lawsuits in total, challenging each regional list separately. Volt co-leader also stated that the party was prepared to bring the case to the
Czech Constitutional Court. By 27 August 3 regional courts had thrown out the case as a final ruling, saying that the 'non-coalitions' were legitimate. In response, Přísaha filed a similar lawsuit against the Pirates' candidate list in the
Ústí nad Labem Region on 20 August, related to the inclusion of Green Party members. The last lawsuit was resolved on 3 September, when the ruled that Stačilo's "circumvention of law is clearly visible and has reached heaven-appealing levels" and that "all requirements needed for a denial of registration were met". However, it chose to register the party list, saying that "courts should very seldomly influence the electoral process" and stated that lawmakers should clarify the law. Volt said they would appeal the case to the Constitutional Court, which will rule on the case after the election, during the result certification process. In the end, all lawsuits were rejected, and all originally submitted lists were approved. The unprecedentedly high number of lawsuits led to a delayed start of printing of the voting lists, which was originally scheduled to start on 22 August, but only started on 3 September, the latest feasible date.
Possible coalitions In August, all parties of the original Fiala cabinet (SPOLU, STAN and the Pirates) declared that they were not willing to work with ANO in any future government, and also rejected cooperation with Stačilo! or SPD. Commentators said that it would be possible to re-form the SPOLU-STAN-Pirates government if the parties won enough seats to do so. They also noted that the Pirates would have a bigger influence in this scenario, as they would have won more seats by passing the electoral threshold running as a single party. By the same token, the two parliamentary opposition parties (ANO+SPD) ruled out working with any of the parties in the existing government, while ANO's leader was seen as the most likely Prime Minister after the elections. Commentators suggested that any ANO-led government would be hard to form and maintain, as Babiš would be forced to cooperate with parties on either the far-right or the far-left. In the case of a strong result for both Stačilo! and SPD, Babiš would be forced to form a government consisting of eight parties, the most in Czech history (surpassing the record set by the outgoing government, which originally consisted of five parties).
Czech Radio reported that Babiš was fearful of "lost votes", that would go to parties finishing below the electoral threshold. In 2021, there was over a million such votes, over a fifth of the total votes cast. It was reported that Babiš had pushed for electoral cooperation with Stačilo! and Social Democracy, and a recreation of the
Přísaha and Motorists coalition. A one-party government was seen as the preferred option for ANO after the election, but it was considered unlikely that the party would win a majority on its own. The Motorists were perceived as the most preferred coalition partner for Babiš, Some contributors for
Foreign Affairs and
Seznam Zprávy also warned of the possibility of far-right parties being included in the next government.
President Pavel's opposition to anti-NATO/EU ministers In May, President
Petr Pavel said that he may refuse to appoint ministers who support the Czech Republic's withdrawal from
NATO or the
European Union. In June, he repeated this position, stating that if Stačilo! were in a position to set the country's foreign policy, he would consider this a "direct threat for this country", and that he would not appoint Stačilo! nominees to any ministry with responsibility for "security or foreign policy". He also confirmed that the same would apply to any SPD candidates.
September assault on Andrej Babiš On 1 September, at a pre-election rally in the village of
Dobrá, an elderly man struck Andrej Babiš on the head and the back with a
crutch. The police apprehended the perpetrator at the scene, and investigated the attack as an act of hooliganism. Babiš was taken to hospital, but was discharged and stated on social media that he would likely be fine. In another statement on social media the day after the attack, Babiš said he was awaiting further medical examinations. Following the incident, Babiš cancelled the following day's election rallies.
Campaign incidents In August 2025, media outlets published an audio recording from 2023 in which , a member of parliament and candidate for ANO, expressed intent to hire someone to kill her ex-husband's new partner's dog and damage her ex-husband's business. Balaštíková was removed from the list of candidates. Pavel Jajtner, a physician from
Znojmo, was a candidate ranked 13th on SPOLU's candidate list. Investigative journalists discovered that he had failed to provide adequate care for newborns during a night shift at in January 2022. A confidentiality agreement was reached among regional representatives and family members. Marek Výborný, the leader of KDU-ČSL, for which Jajtner was running, stated that he would investigate the matter on the same day. The following day, Jajtner withdrew from the candidate list. Nemocnice Znojmo was also the subject of another incident. ODS politician Veronika Kachlíková, with the backing of senior ODS figures (including
Pavel Blažek and Karel Podzimek), acquired a former hospital
dormitory in Znojmo that was sold for 38 million CZK, significantly surpassing its estimated value of 15 million CZK. Soon after the sale, local politicians changed the zoning regulations, allowing Kachlíková's company to convert the building into residential apartments, which have since been sold for around 150 million CZK. The acquisition process raised questions about political favoritism and potential
conflicts of interest, especially concerning the involvement of regional ODS leaders who lobbied for the project. Kachlíková denied any wrongdoing, distancing herself from political discussions surrounding the sale and subsequent zoning changes. Karel Podzimek resigned from the candidate list for the SPOLU coalition in the South Moravian region after the allegations emerged of his involvement in the redevelopment.
Public concerns about electoral fraud In May 2025, the media reported that the Czech public were concerned about
electoral fraud on the part of Petr Fiala's cabinet, according to the STEM agency. In September 2025, another survey found that four out of ten Czechs feared election fraud. According to an analyst at NMS, the topic of stolen elections has appeared in the public sphere. ==Endorsements==
