The Crown Prosecution Service (CPS) and Association of Chief Police Officers (AOCPO) have been "too passive" and lacked leadership when tackling FGM, MPs said.
In a damning report into UK efforts to stop the practice, MPs said:
One reason behind the UK's poor record is that the police and Crown Prosecution Service have historically been far too passive in their approach to FGM by waiting for survivors to come forward.
Yet the nature of FGM means that it is unlikely that this will happen.
It is unacceptable that those in a position with the most access to evidence of these crimes do nothing to help the victims and those at risk.
A key objective for a national action plan on FGM must be to overcome practitioners' own reluctance to address FGM so that they respond to it in the same way as other forms of child abuse.
