US President Donald Trump arrived at Windsor Castle on Wednesday, kicking off a two-day state visit to Britain as the guest of King Charles III. The president’s Marine One helicopter landed in the private Walled Garden at the Windsor estate. Prince William and his wife Catherine were on hand to meet the president and First Lady Melania Trump, walking them over to be greeted by the king and Queen Camilla.

Carriages have been polished, hundreds of troops have been drilled to perfection, the family silver is being laid out, and diamonds are being dusted off for a day of royal pageantry on the president’s unprecedented second state visit to Britain. No US president, or any other world leader, has ever had the honour of a second UK state visit.
