Prince Harry has talked about his feelings for his mother Diana, Princess of Wales, in a revealing interview.
Harry struck up a friendship with four-year-old Aids orphan Mutsu
He vowed to make his mother proud and to carry on her legacy but insisted no-one could take over her role.
The 20-year-old prince said he and his brother William "try to be normal" but it was "very difficult" in the face of negative press coverage about Diana.
Harry was interviewed on camera for a documentary he made about Aids orphans in Africa while on his gap year.
Some of the footage for The Forgotten Kingdom: Prince Harry in Lesotho was shot by the teenage royal using his own hand-held video camera.
He spent eight weeks in the impoverished southern African country Lesotho working at a children's orphanage.
The hour-long documentary, said to be the prince's own idea, will be broadcast on Sunday on ITV.
In the interview, Harry says it is a shame only bad "stuff" seems to come out about his mother despite her good deeds.
He thinks Diana would have supported his work with Aids orphans.
"I believe I've got a lot of my mother in me, basically, and I think she'd want us to do this, me and my brother," he says.
The documentary shows Harry playing with Aids orphans at the Mants'ase Children's Home in Mohale's Hoek.
About 40% of Lesotho's population is thought to have HIV or to be infected by Aids.
In the film, Harry says: "I always wanted to go to an Aids country to carry on my mother's legacy as much as I can.
"I don't want to take over from her because I never will. I don't think anyone can, but I want to try to carry it on to make her proud."
The prince struck up a friendship with four-year-old Mutsu Potsane, a "really special kid" thought to be HIV positive.
He is also filmed cradling 10-month-old Liketso, a baby girl raped by her mother's boyfriend, and sitting on the beds of women with full-blown Aids as doctors check on them.
At the start of the prince's trip, tapes secretly recorded by Diana were broadcast in the US detailing her troubled marriage, the Prince of Wales' affair with Camilla Parker-Bowles, her struggle with bulimia and apparent suicide attempts.

Harry says he wishes that, years on from his mother's death, it was not just bad "stuff" which came out about her.
He says: "It's a shame that after all the good she's done, even this far on people can't bring out the good in her."
He adds: "All I'm doing out here is what I want to do, doing what she'd want me to do."
Harry, who has been portrayed in the papers as a keen night clubber, said he and William tried to let the press coverage wash over them.
"William and I try to be normal, it's very difficult, but you know, we are who we are."
The documentary also contains interviews with doctors, aid workers and Prince Seiso, the brother of Lesotho's King Letsie III who put together the itinerary for Harry's stay.
The Forgotten Kingdom: Prince Harry in Lesotho will be broadcast on ITV1 at 1830 BST on Sunday.
