Ukrainian President Zelensky has repeatedly stated that any peace agreement involving territorial concessions or major security arrangements with Russia would require public approval via national referendum, consistent with constitutional provisions on altering territory. Early 2026 reports highlighted U.S.-backed discussions of holding such a vote alongside presidential elections, potentially in May, amid renewed negotiations, though timelines slipped due to unresolved issues like Donbas control and the absence of a ceasefire. Civil society groups have challenged the referendum concept as legally problematic, while public polling shows strong resistance to ceding occupied regions. No binding schedule has advanced amid stalled diplomacy, with resolution hinging on verifiable ceasefire commitments and parliamentary action.
