Speaking at a party congress in Ede on 27 June, JA21-leider Joost Eerdmans set a condition for his party’s support on the upcoming budget plans: the financial package must include tax relief, otherwise the minority D66‑VVD‑CDA cabinet would be forced to meet Pro‑leider Jesse Klaver’s demand to reverse social‑security cuts, which Eerdmans said would cost “billions.” Both leaders have now definitively ruled out working with each other, leaving the coalition without an obvious majority partner ahead of Prinsjesdag.
