01 · EU — Merz Proposes “Associate Membership” for Ukraine With Mutual Defence

German Chancellor Friedrich Merz proposed an “associate membership” for Ukraine in a letter to European Council President António Costa and Commission President Ursula von der Leyen, a status that would bring Kyiv substantially closer to the bloc while the lengthy full-accession process continues. Under the plan, Ukraine’s leader would attend EU summits and have non-voting representation in the Commission and Parliament, but without voting rights or a dedicated portfolio.

Crucially, the proposal would extend the EU’s mutual-assistance clause under Article 42.7 to Ukraine, creating a “substantial security guarantee” as an alternative to near-term NATO membership, and would allow access to parts of the EU budget step by step. Merz floated the same model for Moldova and the Western Balkans. Kyiv has pushed back, with one official labelling it “shadow membership.” The proposal may be discussed at the June 18-19 European Council, where the Cyprus presidency is pressing to open the first accession cluster.
