The District of Columbia mistakenly placed several Australian ​flags instead of British flags near ‌the White House ahead of King Charles’ US visit, although the error was quickly ​corrected, a DC Department of ​Transportation official said on Friday.

Charles is also ⁠the head of state for ​Australia, but the role is largely ceremonial.

Fifteen ​Australian flags were briefly included among more than 230 flags put on display to welcome ​the British king when he arrives ​in the US capital on Monday. They were ‌later ⁠replaced with the British flag, the official said.

Charles’ state visit, to mark the 250th anniversary of the US Declaration ​of Independence ​from ⁠British rule, is widely seen as the most high-profile trip ​of his reign so far.

The ​trip ⁠will aim to shore up the two allies’ “special relationship,” which has sunk to its ⁠lowest ​point in 70 years ​amid strains surrounding the Iran war.
