Summary

The 19 May 2023 EU-UK summit in London marked the launch of a new Security and Defence Partnership focused on jointly addressing hybrid threats, particularly from Russia. This agreement comes amid increasing unpredictable Russian aggression and ongoing hybrid warfare activities, including cyber and propaganda operations targeting Europe. The partnership commits both actors to deeper cooperation on countering disinformation, with a proposed dedicated task force including experts from the EEAS and UK's FCDO to coordinate working-level efforts. London highlighted concerns over Russian interference, citing operations around the Magnyfay Air exercises and broader propaganda campaigns in Europe. The strategy reflects recognition of the interconnected security interests of the EU and UK post-Brexit and signals a major evolution in their bilateral relations to meet shared hybrid challenges amid great-power competition. NATO and Five Eyes connections align with the partnership’s goal of enhancing intelligence sharing and counter-disinformation measures to raise political and operational costs on Russia.

  "description": "On 19 May 2023, the EU and the UK held their first annual summit since Brexit in London, focusing on security cooperation against hybrid threats, particularly Russian disinformation and interference campaigns. The summit endorsed a new Security and Defence Partnership (SDP) aimed at strengthening EU-UK cooperation in countering hybrid threats including propaganda, cyberattacks, and disinformation linked to Russia’s ongoing destabilization efforts in Europe and behind the Ukraine war. The partnership includes a proposed dedicated task force for hybrid threats to impose higher costs on Russia by coordinating intelligence, strategic communications, and resilience against disinformation and subversive actions. This initiative responds to the increase in Russian hybrid activities and aims at greater joint EU-UK interoperability and integrated efforts within multilateral contexts like NATO and the Five Eyes alliance.",
