UK-EU Competition Co-operation Agreement

The European Commission announced a significant step in EU–UK economic relations with the signing of the new EU‑UK Competition Cooperation Agreement on 25 February 2026. The agreement establishes a clearer and more structured framework for collaboration between the European Commission, EU Member State competition authorities, and the UK’s Competition and Markets Authority.

It sets out mechanisms for mutual notification of major antitrust and merger investigations, coordination where appropriate, and strict safeguards for confidential information. Positioned as a supplement to the broader EU‑UK Trade and Cooperation Agreement, this development reinforces both parties’ commitment to fair competition, market transparency, and regulatory stability, key considerations for international trade stakeholders navigating the post‑Brexit landscape.
