London — September 19, 2025:
President Donald J. Trump concluded his second State Visit to the United Kingdom with a sweeping commitment to strengthen the “special relationship” between Washington and London, signing the Technology Prosperity Deal (TPD) with UK Prime Minister Sir Keir Starmer.
The White House called the TPD a “landmark science and technology agreement” that will elevate bilateral cooperation in artificial intelligence, quantum computing, nuclear energy, and biotechnology.
“The bond between the United States and the United Kingdom is like no other anywhere in the world, and we will always be friends,” President Trump said, emphasizing that the two nations must “stand together for liberty and freedom.”
Key Provisions of the TPD:
AI & Science Collaboration: A new flagship “AI for Science” research program will link U.S. government agencies with UK counterparts to advance precision medicine and biotechnology.
Nuclear Cooperation: Regulators from both countries will align review processes, targeting reactor design approvals within two years and site licensing within one year.
Supply Chain Security: The UK pledged to match U.S. commitments to end reliance on Russian nuclear fuel by 2028.
The agreement is expected to deliver $350 billion in commercial outcomes, including major defense and technology purchases. The UK government committed to spend $80 billion on U.S. tech and defense products over the next five years, while British pharmaceutical giant GSK announced a $30 billion investment in AI research and infrastructure in the United States.
Energy giant BP will invest $5 billion in energy production, focusing on the Gulf of Mexico region, the White House said.
Strengthening Defense Ties:
The visit also deepened bilateral defense cooperation. Ahead of the trip, the UK awarded a $540 million contract to Google Cloud to support the Ministry of Defence. The U.S. Defense Innovation Unit and the UK Defence Innovation Organisation signed a declaration to prototype critical emerging technologies jointly, aimed at boosting both nations’ defense industrial bases.
Officials say the TPD will create thousands of jobs, lower energy costs, and help the U.S. and UK maintain their technological edge in a competitive global landscape.
