Overview

• Air Force One landed at Stansted on Tuesday night, with Wednesday’s program at Windsor Castle featuring a carriage procession, a joint UK–US flypast, a wreath‑laying at St George’s Chapel and a state banquet hosted by King Charles III.
• US companies announced or outlined large UK commitments tied to a new tech partnership, including Microsoft’s £22 billion for AI and cloud infrastructure and Google’s £5 billion plan, with Nvidia and OpenAI reported to be collaborating on a sovereign AI platform.
• A vast security operation is in place, with the largest ceremonial welcome in years and about 1,600 police officers deployed in London as protests are planned; police said four people were arrested after images of Trump and Jeffrey Epstein were projected onto Windsor Castle.
• Trump meets Prime Minister Keir Starmer at Chequers on Thursday for talks expected to cover tariffs, a tech pact and civil‑nuclear cooperation, with media reporting multi‑billion‑dollar deals could be signed and a joint press conference planned.
• The visit unfolds under political scrutiny after the sacking of UK ambassador Peter Mandelson over Epstein links, with Trump’s itinerary largely confined to Windsor and Chequers and no parliamentary address scheduled while the Commons is in recess.
