One in five UK police forces is failing to properly record cases of so-called honor violence against women, according to a support group.

It said there was a “postcode lottery” when it came to recording such crimes.

The report, from the Iranian and Kurdish Women’s Rights Organisation (IKWRO), also highlighted a lack of proper risk assessment of victims.

The Association of Chief Police Officers (Acpo) said “significant progress” had been made by forces.
