On 1 July, the nationalist Portuguese party Chega, with two MEPs, became the fourth member of the Patriots for Europe.[28][29] On 5 July, the Spanish Vox party also joined, leaving the European Conservatives and Reformists (ECR) group.[30] The same day, the Dutch Party for Freedom (PVV), formerly part of the ID Group, also announced it would join.[31] 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.[32][33] On 8 July, the National Rally (RN) and Lega were announced as new members of the group.[34][35] 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.[36] 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".[37]
During the formation process, parties previously speculated as possible members of the new EU Group included:[38][39][40]
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,[41] with the AfD stating it had no current plans to join.[42] 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.[43]
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.[47] Although it was later rejected from S&D,[48] Smer–SD declined to join Patriots for Europe, saying that it can not join the group that "has nothing to do with social democracy".[49][50]
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.[51][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]
^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.
^Part of the Confederation alliance. Its other members did not join.
^The party contested the 2019 European Parliament election as a member of ID, but failed to win any seats. After the 2024 election, the party gained representation, but decided to join PfE instead of sitting with the collapsing ID.
