Episode description

Last November, a faked audio clip of London's mayor went viral. Marianna Spring talks to Sadiq Khan about the impact it had and tracks down it's suspected creator.

The clip used artificial intelligence to create a replica of Mr Khan's voice saying words scripted by the faker, disparaging Remembrance weekend with an expletive and calling for pro-Palestinian marches to take precedence.

In this series, Why Do You Hate Me?, Marianna Spring delves into her inbox to investigate extraordinary cases of online hate like this one. She meets the people at the heart of the conflicts, and in some cases brings them together, to see if understanding – even forgiveness – is ever possible.
