This article intends to illuminate the role played by mothers within ‘honour’ based abuse (HBA) crime, an issue that is both obscured and under researched. Findings are drawn from 100 HBA investigations (2012–2014) and fifteen semi structured interviews (2016) with specialist police officers in one UK police force. The findings show that mothers play fundamental, indeed “massive” role in perpetrating honour abuse against daughters. Mothers inflict violence, sometimes with an intention to induce an abortion; they inflict hard psychological abuse and condone the violence inflicted by other male relatives, mainly sons. This article challenges the ability for mothers to effectively safeguard child victims of HBA. Police under recording of female perpetration is apparent. Victim loyalty and reluctance to prosecute mothers contributes to the blurred of boundaries between mothers as ‘perpetrators’ and mothers as secondary ‘victims’ acting under duress. Such factors adversely affect the policing response.
