IntroductionSince the United Kingdom’s (UK) withdrawal from the EU in 2020, the parties have continued to cooperate on various digital policy issues. While their regulatory approaches differ in some areas – notably AI – their broader objectives are similar. Both the EU and the UK are pursuing greater digital sovereignty and enhanced global competitiveness, seeking to reduce their strategic dependencies in critical technologies in an increasingly adversarial geopolitical context.
Digital cooperation is evolving alongside efforts to strengthen and formalise the EU-UK partnership. For example, at the first EU-UK summit on 19 May 2025, the parties agreed to establish a new strategic partnership. While digital policy was not explicitly mentioned in the summit’s joint statement, the document outlining the security and defence partnership mentioned further cooperation on cyber issues, countering hybrid threats, strengthening the resilience of critical infrastructure, and addressing FIMI, including through coordination in multilateral fora, such as the G7.
Core frameworkThe EU-UK relationship is governed by the Withdrawal Agreement, the EU-UK Trade and Cooperation Agreement (TCA), and the Windsor Framework. The TCA explicitly recognises the parties’ ‘right to regulate’ in their respective jurisdictions, while also expressing their wish to cooperate in areas of mutual interest. For example, they have committed to ensuring cross-border data flows, facilitating digital trade and holding regular cyber dialogues. According to Article 776 of the TCA, the parties have to review the implementation of the agreement in 2026, five years after its entry into force. Digital trade issues are discussed in the joint Trade Specialised Committee on Services, Investment and Digital Trade.
In accordance with the TCA, the European Parliament and the UK Parliament established a Parliamentary Partnership Assembly (PPA) in 2021 to enable the exchange of views on the implementation of the TCA. Parliamentarians meet twice a year, with the next EU-UK PPA scheduled to take place in Brussels on 16-17 March 2026.
Since 1 January 2024, the UK has been associated to the Horizon Europe programme.
Artificial intelligenceAlthough the EU and the UK have different approaches to AI regulation, they share the common goal of promoting the responsible development and uptake of AI. The EU has adopted a comprehensive risk-based regulatory framework through the 2024 AI Act, categorising AI systems by risk and imposing strict obligations on high-risk areas such as critical infrastructure, while banning harmful practices. Minimal-risk AI systems remain largely exempt. In November 2025, the Commission proposed a digital omnibus on AI – amendments to the AI Act – on which the Council and Parliament are currently working.
The UK prefers a lighter-touch approach, regulating AI rather in the context in which it is used. It has established an AI Security Institute and adopted an AI opportunities action plan to boost AI investment, uptake and development. In March 2025, a private member’s bill, the Artificial Intelligence (Regulation) Bill, was introduced in the House of Lords, but, it has not made significant progress. If passed, it would create a central AI authority to oversee AI governance.
Both the EU and the UK are pursuing initiatives to strengthen the AI ecosystem. In April 2025, the European Commission published an AI continent action plan to build large-scale AI data and computing infrastructure across Europe, including AI factories and AI gigafactories. The UK is participating in the AI factories initiative and planning to host an AI factory antenna at the University of Edinburgh. The UK is also establishing its own AI Growth Zones – designated sites for AI-enabled data centres and supporting infrastructure.
At the international level, the EU and the UK collaborate on AI safety and security through their respective bodies – the EU’s AI Office and the UK’s AI Security Institute. The EU and the UK have both signed the Council of Europe Framework Convention on AI, adhered to the OECD AI principles, contributed to international AI safety reports, and worked on shared approaches for measuring and evaluating advanced AI capabilities. They also cooperate on AI standards development through CEN and CENELEC (the European Committee for Standardization and the European Committee for Electrotechnical Standardization). However, the UK has not signed some AI declarations, such as the Paris AI Action Summit Declaration.
Data flowsBoth the EU and the UK are committed to maintaining seamless cross-border data flows. In December 2025, the Commission renewed the two adequacy decisions originally adopted in 2021, confirming that personal data may continue to move freely and safely between the European Economic Area (EEA) and the UK. The Commission concluded that the UK legal framework contains data protection safeguards essentially equivalent to those in the EU. Unless extended, the decisions will expire on 27 December 2031.
Cyber dialoguesThe EU and the UK have been holding regular cyber dialogues, as set out in the TCA. Since December 2023, three formal cyber dialogues have taken place: the first in Brussels in December 2023, the second in London in December 2024 and the third in December 2025 in Brussels. These meetings are used to align positions on international cyber norms, exchange views on cyber threats and coordinate responses to malicious cyber activity. Parties provide updates on policy and regulatory developments. The next dialogue will be held in 2026 in London.
Online platforms and search enginesIn May 2024, the European Commission’s DG CNECT signed an administrative arrangement with Ofcom – the UK’s regulator for communications services. The arrangement will support the enforcement of the EU’s Digital Services Act (DSA) and the UK’s Online Safety Act, which introduce new obligations for online platforms and search engines, including measures to protect users from illegal and harmful content. The two authorities plan joint training, expert dialogues and studies on issues such as protection of minors, age-appropriate design and platform transparency.
European ParliamentThe European Parliament has repeatedly encouraged close cooperation with the UK on digital issues. In its resolution of 27 November 2025 on the implementation of the EU-UK Trade and Cooperation Agreement, Parliament welcomed the administrative arrangement signed between the Commission and Ofcom, as well as plans to extend data adequacy decisions. It asked the UK not to go too far from the fundamental principles of the two main EU digital regulations: the Digital Markets Act and the DSA.
