Prince William has decided to leave the armed forces after more than seven years in order to spend more time campaigning for conservation, Kensington Palace announced today.
The Duke completed his final shift as a search and rescue pilot in Anglesey on Tuesday, and will now move to Kensington Palace with the Duchess and their new son Prince George.
He will continue to carry out royal engagements both at home and overseas but is not expected to increase his number of public duties.
In an upcoming ITV documentary, he says he feels a strong sense of protection towards endangered animals and the natural environment.
ITV News' Royal Correspondent Tim Ewart reports:
The Duke and Duchess of Cambridge started this new stage in their lives by attending a charity function in London tonight for the wildlife charity Tusk, for which William is a patron.
A statement from Kensington Palace said that as well as his charitable work, he was also "considering a number of options for public service":
In an upcoming ITV documentary, the Duke hints that his future role will build on his passion for Africa and wildlife:
The Duke has worked as a search and rescue pilot with the RAF on Anglesey for the last four years, but will leave operational work behind.
Air Chief Marshal Sir Andrew Pulford said the Duke had been an "integral part" of the team and had "earned the respect of all who have worked with him".
The Duke and Duchess will soon move into their refurbished Kensington Palace apartment following the birth of their son, Prince George, in July.
