US President Donald Trump formally begins his unprecedented second state visit to Britain on Wednesday (September 17, 2025) with the royal pomp a grand veneer to key diplomatic talks, and as difficult questions about Jeffrey Epstein linger, Reuters reported.

King Charles and the royal family will roll out the red carpet for the president when he arrives at Windsor Castle, the oldest and largest inhabited castle in the world and family home to British monarchs for almost 1,000 years, with a carriage procession, gun salutes, a military flypast and lavish banquet.

Britain says it will be the largest military ceremonial welcome for a state visit in living memory, according to Reuters.
