EU’s von der Leyen: Libya-Turkey Mediterranean deal invalid, violates third-country sovereignty

Brussels is escalating from diplomatic objection to a formal legal verdict, which raises the stakes for Ankara and for the eastern Mediterranean gas and maritime boundaries at issue. The explicit invocation of solidarity with Greece and Cyprus signals the dispute is being folded into EU-Turkey relations more broadly, not treated as a bilateral matter. The open question is whether this legal position translates into concrete EU measures, and how Turkey responds to an agreement being declared invalid rather than merely contested.
