Overview

• At Chequers, President Trump and Prime Minister Keir Starmer signed a technology cooperation package covering artificial intelligence, quantum computing and nuclear energy, described as the Prosperity/Tech deal.
• U.K. and U.S. officials highlighted multibillion‑dollar commitments, with expectations of more than $10 billion in agreements, a Microsoft plan for $30 billion in U.K. investment, and GSK pledging $30 billion in the United States.
• Talks also covered tariffs on British steel and aluminum, defense cooperation and support for Ukraine, with a joint news conference planned before Trump’s departure.
• Day one featured an unusually large Windsor welcome—41‑gun salute, about 1,300 troops, 120 horses, a carriage procession and a state banquet where King Charles III praised Trump’s personal efforts to resolve global conflicts.
• Protests continued in London and Windsor as activists projected images linking Trump to Jeffrey Epstein on a Windsor tower, prompting arrests, and coverage noted Trump briefly walked ahead of the King during a guard inspection.
