Yvette Cooper calls for greater monitoring of online harassment

Senior Labour MP says police and prosecutors should do more to unmask extent of online misogyny, racism and homophobic abuse

Online harassment and abuse is "stifling debate and ruining lives", according to Yvette Cooper, who is calling on police and prosecutors to follow the Guardian's lead in unmasking the true extent of the problem.

The senior Labour MP warned that misogyny, racism and homophobic abuse were all growing online, as was revenge pornography, in which people distributed sexual photos or videos of former partners without permission.
