The European Council adopted conclusions agreed by all 27 member states in June 2026, the first time this had happened since December 2024.

Omissions

• The exact comparative framing 'first time since December 2024' is corroborated indirectly: sources confirm the March 2025 and October 2025 conclusions were adopted 'at 26' (without Hungary), and the Council's own June 2026 page highlights unity of all 27, but not every individual summit between December 2024 and June 2026 (June 2025, December 2025, March 2026) was separately verified in this search.
• No source found in this search directly states that the December 2024 European Council (19-20 December 2024) was the last previous meeting with conclusions adopted at 27; this is the implied baseline of the claim and is consistent with, but not explicitly confirmed by, the sources located.
• The Consilium pages describing the June 2026 meeting were published on or shortly after 18-19 June 2026, i.e. before the session date of 8 July 2026; all other sources cited (March and October 2025) predate the session.
