On 1 July, the nationalist Portuguese party Chega, with two MEPs, became the fourth member of the Patriots for Europe.[27][28] On 5 July, the Spanish Vox party also joined, leaving the European Conservatives and Reformists (ECR) group.[29] The same day, the Dutch Party for Freedom (PVV), formerly part of the ID Group, also announced it would join.[30] On 6 July, the Danish People's Party and Vlaams Belang, both part of the ID group, announced they would also join, bringing the group above the minimum number of member states required for an official European Parliament group.[31][32] On 8 July, the National Rally (RN) and Lega were announced as new members of the group.[33][34] The prerequisite for establishing a political group of the European Parliament is the membership of at least 23 MEPs from at least seven EU member states. The alliance met this criterion on 6 July 2024.[35] According to Le Monde, the RN waited until after the second round of the 2024 French legislative election for the announcement "for fear of reviving suspicion of pro-Russian sympathies".[36]
During the formation process, parties previously speculated as possible members of the new EU Group included:[37][16][38]
Germany: Alternative for Germany (AfD), which has 15 MEPs (formerly part of the ID Group). However, due to previous tension between Fidesz and AfD, this was seen as unlikely,[39] with AfD stating it had no current plans to join.[40] AfD expressed interest in creating a group including Hungarian Fidesz rival Our Homeland Movement and the Bulgarian Revival. These parties eventually established a separate far-right grouping, Europe of Sovereign Nations.[41] Fidesz leader Viktor Orbán later stated in an interview that the National Rally had objected to AfD joining the Patriots for Europe group.[42]
Slovakia: Smer–SD was speculated to join the alliance with its five MEPs; however, according to its junior coalition partner, Hlas–SD, Smer–SD expressed a preference for rejoining the S&D group.[46] Although it was later rejected from S&D,[47] Smer–SD declined to join Patriots for Europe, saying that it can not join the group that "has nothing to do with social democracy".[48][49]
Slovenia: The Slovenian Democratic Party (SDS), which won four MEPs, ultimately remained part of the EPP Group, while noting that not all SDS MEPs agreed with this decision.[50][51]
Romania: The Democratic Alliance of Hungarians in Romania (RMDSZ), which won two MEPS, announced that the party will remain in the EPP group, because they believe that Hungarian interests can be asserted by being in separate factions, and because Fidesz has not approached them to join.[52]
The Polish Confederation's National Movement, which won two MEPs, announced in July 2024 that it was in negotiations with Patriots for Europe, while the three Confederation MEPs from New Hope joined the ESN group, and the one Confederation of the Polish Crown MEP was not seeking to join.[56][57][58] Ultimately, the National Movement joined Patriots for Europe on 1 October.[59]
Following the expulsion of Luxembourgish Alternative Democratic Reform Party (ADR) MEP Fernand Kartheiser from the ECR group, the Patriots for Europe group approached the ADR for talks. The ADR stated that while it was considering what group the party wanted to belong to if the whole party were fully expelled from the ECR, it was not yet actively discussing membership with any other political group.[60]
Patriots for Europe has MEPs in 13 member states. Dark purple indicates member states sending multiple MEPs, light purple indicates member states sending a single MEP.
^ANO announced its departure from ALDE and Renew Europe on 21 June 2024, with leader Andrej Babiš declaring that ANO would not be able to fulfill its program as part of those groups. ANO considered joining other EU political groups after its departure, before successfully negotiating the creation of the Patriots for Europe alliance with Fidesz and the FPÖ.
^KDNP left the EPP party and the EPP group, after the EPP group decided to admit the TISZA party. After the creation of the Patriots for Europe alliance, KDNP decided to join.
