Thousands of people have been marching through the streets of Belem to demand stronger action on tackling global warming, as the UN climate summit continues in the Brazilian city. Indigenous communities, youth groups, and climate activists from across the world were among those joining the rally to mark COP 30's half-way point. We speak to Panama's special representative on climate change Juan Carlos Monterrey Gomez.

Also in the programme: President Trump has hit out at Georgia congresswoman Marjorie Taylor Greene who had been one of his closest allies; why Iceland's former Prime Minister is worried her native language is under threat; and as Pope Leo holds an audience with some of Hollywood's biggest stars, we speak to a nun who is also a film critic.
