Prince William has revealed a sweet wish he is harbouring involving his three children Prince George, Princess Charlotte and Prince Louis.

The Prince of Wales spoke to the BBC and Sky News ahead of his fourth annual Earthshot Awards, being held in Cape Town tonight.

Five global winners will each receive £1 million in prize money to develop and scale up their solutions to environmental and climate change issues in a glitzy ceremony.

Prince William wished that his three children and his wife Princess Kate would be watching the event being broadcast around the world.

He said that he and his family have conversations about trying to “do what they can” at home to protect the environment. The prince said: “Yeah, well, you know, every family tries to do what they can to sort of help with the environment.

“We go through all the basics of recycling and making sure we minimise water use and turning off lights when we leave the house and stuff like that, and making sure, which is sensible in what we do around the environment.

“I think every family has these conversations. You just try to do what you can. The Earthshot Prize has got to be a bit more global than that. We are trying to do big scale ambition and big scale business to tackle some of the solutions.

“But I brought the children along that journey and tonight I hope they are watching and they are proud of kind of what we are trying to do here, which is to really galvanise that energy that enthusiasm to make real impact.”

The Prince of Wales was also seen wearing a “Papa” friendship bracelet made by his daughter Princess Charlotte for Taylor Swift’s Eras Tour at Wembley in June.

“Well, this is… a relic, if you like, from a Taylor Swift concert that my daughter decided that she wanted to create a bracelet for,” he said. “She gave it to me when I came away. So I promised that wear it and try not to lose while I was out here.”

Tonight’s awards will be held in a reusable eco ‘super dome’ with a green carpet for guests such as host Billy Porter and models Heidi Klum and Winnie Harlow. Prize winners were chosen from nearly 2,500 nominees across 75 countries.
