Overview

• President Donald Trump arrives Sept. 16–18 for a Windsor-centered program featuring a carriage procession, flypast and state banquet before talks with Prime Minister Keir Starmer at Chequers.
• Starmer’s office says the leaders will sign a “world-leading tech partnership” and a “major civil nuclear deal,” with further cultural initiatives also slated for announcement.
• Tariff relief for steel and aluminium remains under negotiation after car and aerospace concessions in June, with Parliament’s Business and Trade Committee urging maximal pressure during the visit.
• The UK announced more than £1.25 billion in new U.S. investment from firms including PayPal and Bank of America, while sources say Nvidia and OpenAI are expected to unveil UK data‑centre commitments and CoreWeave plans to detail investments this week.
• The trip unfolds under intense security with large protests expected, and follows Starmer’s dismissal of ambassador Peter Mandelson over ties to Jeffrey Epstein, a complication for the diplomatic backdrop.
