The Dutch political parties GroenLinks and PvdA announced they will run together in 80% of municipalities during the March 2026 local elections, a significant step towards a potential merger. Despite enthusiasm in many areas, some local chapters remain hesitant, preferring to run separately. Concerns exist within the PvdA regarding the dilution of their socialist principles amidst growing collaboration. Both parties aim to solidify their alliance post-elections, paving the way for a possible new leftist party, with discussions ongoing among their members.
