Feminist campaigner Caroline Criado-Perez says Twitter needs to "get a grip" on security as it emerged bosses were likely to face a grilling from MPs.
The campaigner, who was besieged with sexually explicit threats on Twitter after she campaigned for the faces of women to be included on banknotes, said the social network was ill-equipped to handle episodes of sustained abuse and needed to work more closely with police to deal with internet trolls.
Ms Criado Perez, 29, met Twitter directors on Monday along with MP Stella Creasy who received a similar torrent of abusive messages after she offered support to the freelance journalist.
