The Duke of Cambridge and his brother Prince Harry have presented 20 young people with a new award set up in memory of their late mother Princess Diana.
The royal siblings - the grandchildren of Queen Elizabeth - dished out the Legacy Awards to children from the UK, United States, Canada, India, Belize and the United Arab Emirates who have made a positive change in their communities.
Prince William made a heartfelt tribute to his mother - who tragically died in a car crash in 1997 - in which he said she still inspires "countless acts of compassion."
This was first time William and Harry - whose father is Prince Charles - had made a joint appearance at an event run by the Diana Award, which was established to promote the late princess' belief in the positive power of young people.
The 34-year-old duke - who has two children George, three, and Charlotte, two, with his wife Duchess Catherine - said: "We are so glad our mother's name is being put to good use through The Diana Award."
Jemima Browning, 16, was one of the award winners as she started a swimming club for young people with disabilities called Tadcaster Stingrays after she was inspired by her Down's Syndrome brother Will, 14.
She told the BBC: "It doesn't feel real, it feels really strange it feels like I don't deserve something amazing like this.
"To be able to stand in front of two amazing people who are recognised across the world is just a massive honour and I can't believe it really."
