Live from COP25: Climate summit starts in Madrid

As the two week COP25 climate summit begins in Madrid we are there speaking to some of the representatives, scientists and protesters finding out what people attending hope will come out of the fortnight. We also speak to our environment correspondent who will be answering listener questions from around the world.

Also, we bring you and update on the London Bridge knife attack on Friday where two people were killed. We hear voices from the memorial for the victims and speak to our correspondent from the Fishmongers' Hall where the attack happened.
