A group of 14 MEPs, led by Tiago Moreira de Sá (PfE), has submitted a written parliamentary question to the European Commission challenging recent proposals for differentiated integration and majority voting in EU foreign and defence policy. The MEPs argue that mechanisms such as enhanced cooperation and a 'two-speed Europe', promoted by Commission President Ursula von der Leyen and EPP leader Manfred Weber, risk fostering a 'camouflaged federalism' that shifts authority from national capitals to EU institutions under the guise of strategic autonomy.
The question, filed on 9 April 2026 under Rule 144, asks the Commission three specific points: how differentiated integration without unanimity can be reconciled with national sovereignty and Treaty compliance; how the Commission justifies diminishing the unanimity requirement in foreign and defence policy; and how it distinguishes genuine strategic autonomy from an incremental shift toward supranational federalism that reduces national accountability.
Concrete asks and policy orientation The question contains no numerical targets or deadlines but seeks a clear legal and political justification from the Commission. The MEPs' orientation is sceptical of deeper integration, emphasising national sovereignty and the role of elected national parliaments. They frame the debate as a cleavage between EU-level efficiency (majority voting) and national consent (unanimity), with implications for the balance of power between EU institutions and member states.
Expected follow-up The Commission is expected to reply within approximately six weeks. Its answer will signal whether it defends differentiated integration as Treaty-compliant and necessary for EU responsiveness, or whether it acknowledges concerns about sovereignty. The reply will be closely watched by both federalist and sovereignist camps ahead of the next European Council.
