A Star-Studded Night in Rio
The ceremony drew an array of notable guests, including Leonardo DiCaprio, Energy Secretary Ed Miliband, former New Zealand Prime Minister Dame Jacinda Ardern, London Mayor Sadiq Khan, and former Formula 1 World Champion Sebastian Vettel.
Performers Kylie Minogue and Shawn Mendes also walked the “green carpet” with the Prince. Mendes shared a heartfelt moment, thanking William for his kindness toward his mother. “She’s still shaking, thank you,” Mendes said. In response, the Prince revealed that he had arranged a birthday cake and candles for her special day.

Sir Keir Starmer’s Message to the Next Generation
Before the ceremony, Sir Keir met four Brazilian children representing “mini-Cop,” a youth initiative focused on environmental projects. Later, speaking with students aged 11 to 18, he highlighted the importance of including young voices in climate discussions.
“You have to live with them longer than anyone else, so we need your voice,” the Prime Minister told the students.
Sir Keir also spoke with Adam Root, CEO of Matter—a company developing filters to capture microplastics from washing machines. Impressed by the innovation, the Prime Minister said it would be “really good to do more” when Root expressed interest in collaborating.
