LONDON (AP) — Prince Harry, the son of King Charles III and fifth in line to the British throne, has formally confirmed he is now a U.S. resident.

Four years after Harry and his American wife, Meghan, decamped to a villa on the Southern California coast, a travel company he controls filed paperwork informing British authorities this week that he has moved and is now “usually resident” in the United States.

The formal acknowledgment underscores the prince’s increasing estrangement from Britain, after he and Meghan walked away from royal duties to pursue lucrative media deals in America.
