Facebook’s new global affairs chief, Sir Nick Clegg, has given his first speech since taking on the role.
The event in Brussels came the week after the father of a 14-year-old girl who killed herself said Instagram was partly to blame for her suicide.
The BBC’s media editor Amol Rajan showed Sir Nick some of the self-harm images the BBC had found on the firm’s photo-sharing platform.
If you’ve been affected by self-harm, or emotional distress, help and support is available via the BBC Action Line.
