The Duke of Cambridge has spoken movingly about how the birth of his son has increased the depth of his feelings towards endangered animals.
William was left close to tears after being shown footage of a rhino attacked by poachers and left bleeding to death during filming for a documentary.
The royal was interviewed in July soon after the birth of his son Prince George and in the programme, to be screened by ITV and CNN, talks about his passion for wildlife and how fatherhood has changed him.
But it's not just nature's impressive big animals that have an effect on the royal, he also revealed how he is "not so good" with spiders and snakes.
Documentary film maker Jane Treays said the prince told her: "The wildlife is incredibly vulnerable and I feel a real protective instinct, more so now that I am a father, which is why I get emotional about it... you want to stand up for what is very vulnerable and needs protecting."
