Facebook's response over sexualised child images is 'extraordinary'

MP critical after BBC sends evidence to Facebook, which at first removes only 18% - and reports corporation to police

"Grave doubts" have emerged about the effectiveness of Facebook's moderation system after an investigation revealed the social network was failing to remove sexualised images of children even after they were reported.

Damian Collins, chair of the culture, media and sport committee, made the comments as he criticised Facebook's handling of the images, dozens of which were reported to the company by the BBC and fewer than 20% were removed.
