King Charles III has been making official visits to the US throughout his adult life, but his first trip since being crowned monarch may be his most interesting yet.
On Monday, he will arrive for an official state visit where he will travel to Washington DC, Virginia and New York before departing for Bermuda.
The US trip is the first by a reigning British monarch in almost 20 years, since Queen Elizabeth II accepted an invitation from President George W Bush in 2007.
His past trips have included playing polo in Florida, chatting to presidents as far back as Richard Nixon and meeting American A-list celebrities.
