Overview
- The two parties officially founded Progressief Nederland (PRO) this weekend and have declared that new ballots will use the PRO name with provincial identifiers.
- Provincial and municipal groups may keep legacy names for now because law and election rules let provincial factions use old names until the 17 March 2027 Provincial Staten elections and municipal groups until the 2030 municipal elections.
- Implementation is uneven: Flevoland and Zuid-Holland already changed their provincial group names to PRO while several provinces remain separate or use combined names and usually continue close cooperation.
- In Utrecht PRO and D66 secured a razor-thin 23-seat majority in the 45-seat council after the CDA left talks, and formateurs Lilianne Ploumen and Victor Everhardt will present the full coalition agreement and candidate alderpersons on 23 June 2026.
- Members in some provinces have already chosen PRO lijsttrekkers—including Jasper Kuntzelaers, Joa Maouche and Anouk Gielen—which signals how the new party will organize election lists and negotiate joint or bloc runs for waterschappen and local councils.
