Prince Harry's ten-year military career ended on Friday as he announced plans to spend three months on the "front line" of wildlife conservation in Africa.
The 30-year-old will leave Britain next week to begin a tour of duty in Namibia, South Africa, Tanzania and Botswana, where he will concentrate on protecting rhinos and elephants.
Kensington Palace said that wherever possible he would be "fully embedded" with conservation staff including park rangers, working the same shift patterns and living in the same accommodation.
The Prince has a lifelong love of Africa and its wildlife, and will be following in the footsteps of his brother, the Duke of Cambridge, who has made numerous trips there as patron of the Tusk Trust charity, and who proposed to the Duchess of Cambridge in Kenya.
Although Prince Harry's last official working day was Friday, he has spent the week carrying out official royal duties and was on leave, meaning he had already said his goodbyes to his comrades.
