Prince William: 'We must do more on illegal ivory trade'

The Duke of Cambridge has called on world leaders to do more to combat the illegal wildlife trade.

Speaking in London at an event for the charity Tusk, Prince William said he wasn't prepared to explain to his children "why we lost this battle when we had the tools to win it."

His comments come ahead of the Convention on International Trade in Endangered Species of Wild Fauna and Flora due to take place in Johannesburg.
