Parliament ratifies NATO missile defence pact

The Plenary of Parliament ratified on Thursday, 17 September 2026 the agreement between the Greek Ministry of National Defence and the NATO Communications and Information Agency (NCI Agency), which concerns Greece’s national contribution to the development of the Alliance’s anti-ballistic missile defence system. In favour of the ratification voted the deputies of Nea Dimokratia and PASOK. Against voted the KKE, SYRIZA and Plefsi Eleftherias. The deputies of Niki and Elliniki Lysi declared themselves “present”. The exact result of the vote, namely the number of votes per parliamentary party, has not been officially announced by Parliament, nor has a detailed table of the voting been released to the public.

The ratification of international agreements by the Plenary constitutes an established parliamentary procedure through which an inter-state or international agreement acquires the force of law of the Greek state. In this case, the agreement concerns Greece’s cooperation with the NCI Agency, the NATO body responsible for communications, information technology and defence technologies systems of the Alliance, within the framework of developing anti-ballistic defence capabilities at alliance level. The vote is part of the broader parliamentary process of ratifying international agreements that the government of the day brings for approval to Parliament, as provided for constitutionally for every agreement that entails commitments for the Greek state towards international organisations and allied structures. Such agreements are usually examined first by the competent parliamentary committee before being brought to the Plenary for a vote.

The vote revealed the differing positions of the parliamentary groups regarding the country’s participation in NATO’s anti-ballistic defence structures. The two parties that took the position in favour, Nea Dimokratia and PASOK, supported the ratification of the agreement, without public detailed statements beyond their vote in the Plenary. In contrast, KKE, SYRIZA and Plefsi Eleftherias voted against the text, while Niki and Elliniki Lysi chose the “present” vote, without the detailed reasoning of each party becoming known. No official statements from parties documenting the reasons for support, opposition or abstention from the vote have been recorded so far, nor has any joint position been announced by the government or opposition regarding the content of the agreement.

After its ratification by the Plenary, the agreement is expected to be published in the Government Gazette, thus completing its incorporation into the Greek legal order as a law of the state. The issue is part of the broader national defence agenda monitored by the Greek politics scene, as the country participates in international agreements of an allied character within NATO. No implementation timeline has yet been announced nor details regarding any costs or equipment related to the agreement. The parliamentary debate around issues of national defence and allied commitments is expected to continue, as the parties that voted against or abstained have expressed, through their vote, a different stance towards Greece’s participation in NATO’s defence structures, an issue which is expected to occupy Parliament and public discussion again in the future.
