A joint declaration of intent between the United Kingdom and Ukraine on an artificial intelligence partnership was published on 24 August 2026 by the Prime Minister's Office, 10 Downing Street. The declaration, attributed to the President of Ukraine and the UK Prime Minister, set out an intent to work as close partners on next-generation, AI-enabled armed forces, combining what it described as Ukraine's battlefield experience with UK technological, industrial and research strength.

The text outlined three pillars: government-to-government work on co-developed models, secure data and compute pathways and joint assurance; industry cooperation coordinated through government arrangements to develop, test and deploy capabilities tied to agreed operational problems; and academic and research work on autonomy, AI assurance, cyber security and synthetic data. It stated that cooperation would respect each party's sovereignty over its assets and data, with safeguards on data, intellectual property and export controls in line with national legislation, and would aim for NATO interoperability.

The declaration said work would proceed on a pilot-first basis, prioritising practical cooperation already underway, with further arrangements to be brought forward within the next few months. It described itself as a statement of shared political intent that does not create legally binding obligations.
