The Prince of Wales was presented with the keys to Rio de Janeiro as he began a five-day visit to Brazil. Prince William was on the city's Sugarloaf Mountain, with a bird's eye view of the iconic Christ the Redeemer statue, as he received the honour from the city's mayor, Eduardo Paes. The prince had travelled to the top of the mountain by cable car, to the surprise of several groups of tourists queuing to travel up the mountain. As he came down again, he posed for selfies with several of the people who had waited to catch a glimpse of him. He is visiting Brazil for the first time with two key environmental missions. On Wednesday he is presenting the Earthshot Prize, the annual award from the charity he set up himself. The following day he will travel to Belem, in the Amazon rainforest, where he is scheduled to deliver a speech as part of COP30, the annual UN climate meeting where governments discuss how to limit and prepare for further climate change.
