Prince William is leaving the armed forces after more than seven years to focus on royal duties and charity work, Kensington Palace said Thursday.
William was a pilot with the Royal Air Force Search and Rescue Force.
Known to his RAF comrades as Flight Lt. Wales, he had been stationed at a search-and-rescue base on the remote Welsh island of Anglesey since 2010.
He has lived there with Kate Middleton and now Prince George.
In the next few weeks, the family will move into their official residence at Kensington Palace, as William considers a "number of options" for public service.
For now, the 31-year-old will focus on his royal duties. He will also expand on his conservation work, dealing particularly with endangered species.
