New political parties A number of new political parties emerged after the previous election. The first was
Pavel Rupar's Voice of Pensioners, founded at its inaugural congress on 20 January 2024 by former
SDS MP and Mayor of
Tržič Pavel Rupar. Ahead of the
2024 European Parliament election, the
satirical party None of the Above was established under the leadership of activist Boris Žulj and former
The Left MP
Violeta Tomić. In the same year, former foreign minister
Anže Logar began building his own political party, and following his departure from SDS, the party
Democrats was formally founded. Another new party,
Karl Erjavec - Trust Party, led by four-time
DeSUS Minister
Karl Erjavec, was established soon afterwards. In early 2025,
Marko Lotrič, President of the
National Council, founded his party
Focus of Marko Lotrič at an inaugural congress held at
Brdo pri Kranju. Later that year,
DeSUS and
Good State merged into the
Party of Generations, led by former
Minister of Labor Vlado Dimovski. Former SDS MP
Dejan Kaloh founded the party
Suvereni, and a party of local lists,
Community, was formed under the leadership of Mayor of
Hrastnik Marko Funkl. The party
Prerod – Party of Vladimir Prebilič was founded by former Mayor of
Kočevje,
2022 presidential candidate and
MEP Vladimir Prebilič, and former
The Left MP and another 2022 presidential candidate
Miha Kordiš founded the socialist party
We, Socialists! Two further projects were reported to be in the process of establishment, The Guard, linked to Catholic podcaster Alen Koman, and
Volt Slovenia, as a Slovenian branch of the pan-European federalist movement
Volt Europa. Unlike Volt Slovenia, The Guard collected 200 signatures in time to establish a new political party, but failed to collect 100 signatures in each of the 8 electoral districts which would place the party on ballot.
Pre-election cooperation Pre-election alliances, mergers, and cooperation talks reshaped the landscape.
Greens of Slovenia first called for the unification of green forces on a joint list.
The Left and
Vesna – Green Party signed a pre-election agreement announcing a joint run in the election; the cooperation was later formally confirmed by both parties in their internal bodies. Talks about cooperation within this broader left-green axis also included the newly established localist party
Community, which is also a potential partner for
Prerod, as was
Party of Generations until they announced they would contest the election alone. In addition, a public appeal on social media, with the liberal activist Jaša Jenull urging
We, Socialists!,
The Left,
Vesna, and the
Pirates to join forces and establish a United Progressive Front. On the centre-left,
Prerod announced talks with the
Social Democrats and related cooperation initiatives on the wider left. However, Prerod later rejected the option of a joint list with SD and announced it would run independently, while leaving open further talks with the
Party of Generations, although they later also rejected this option.
Prebilič also invited the leaders of several centre-left parties to a meeting intended to explore future cooperation, but the meeting did not take place because most invitees declined.
Robert Golob invited SD, The Left, We, Socialists!, Pirates, Prerod, Vesna and unexpectedly
Resni.ca for talks. Resni.ca rejected the offer and
Karl Erjavec claimed that his
Karl Erjavec - Trust Party was not invited because it cannot be "cannibalized". On the centre-right,
Concretely merged into
Democrats, and
New Social Democracy, led by
Andrej Magajna, later announced they were in talks about a united participation with Democrats, which was later abandoned and New Social Democracy didn't file to participate in the election.
New Slovenia and the
Slovenian People’s Party opened talks on possible joint cooperation, and NSi, SLS, and
FOKUS each signed a separate declaration of intent and began coordinating a potential common list and the distribution of constituencies. On the nationalist side,
Suvereni,
United Slovenia Movement and
Party of Slovenian People, MP
Dejan Kaloh,
Andrej Šiško and Ivan Bolfek, announced efforts to form a "sovereigntist–patriotic bloc" and referenced the political action SLOEXIT, proposing Slovenia's withdrawal from the EU and a debate on leaving NATO. Suvereni representatives later appeared at an event organised by Karl Erjavec – Trust Party, where cooperation and the formation of a new parliamentary group were discussed. However, Suvereni subsequently decided to run independently rather than enter an electoral partnership with Karl Erjavec – Trust Party, and
United Slovenia Movement and
Party of Slovenian People announced the forming of the Coaliton of the United Nations. After DVK rejected KZN's lists in three electoral districts, they withdrew from the election alltogether. Eventually, Suvereni decided to participate on the lists of the Trust Party. In the centre, Greens of Slovenia and Party of Generations formed an alliance. Among smaller actors,
None of This and
For a Healthy Society announced plans for a joint electoral list, while Resni.ca was reportedly invited but declined.
Leadership changes The Left were the first to change coordinators when they replaced
Luka Mesec with
Asta Vrečko in 2023. Social Democrats were next when they elected
Matjaž Han as party president, after
Tanja Fajon resigned after
Litijska Affair. In 2025, several parties reaffirmed their leaders or elected new ones.
Slovenian Democratic Party subsequently held its congress, at which
Janez Janša was reconfirmed as party president and continuing his 33-year long streak at the helm of the party.
New Slovenia then followed as they elected
Jernej Vrtovec as party president, succeeding
Matej Tonin.
Freedom reaffirmed
Robert Golob as party president at its electoral congress. The electoral congress of
The Left followed, with current coordinator
Asta Vrečko and former coordinator
Luka Mesec confirmed as co-coordinators.
Vesna reconfirmed its co-leadership, with
Urša Zgojznik and
Uroš Macerl continuing as co-presidents.
