Lord Davies of Gower (Con)

My Lords, I am grateful to noble Lords who have spoken, and I am grateful to my noble friend Lady Cash both for bringing forward this amendment and for the clarity with which she set out the problem that it seeks to address. I speak in support of the amendment. It is fundamental to our safety and justice system that police data is accurate and fit for purpose. I am grateful for the warm words that the noble Baroness, Lady Chakrabarti, spoke about me. I hope that I will not disappoint her too much when I say that sex is not an incidental characteristic in policing or criminal justice: it is a foundational variable. Patterns of offending, particularly in relation to serious violence, sexual offences, domestic abuse and repeat high-harm crime are profoundly sex-disaggregated. I would say to the noble Baroness, Lady Donaghy, that police forces depend on this data to analyse trends, assess risk, deploy safeguarding interventions and evaluate whether strategies, including those endorsed by your Lordships’ House, are actually working. If police records cannot reliably distinguish males from females, risk assessment collapses, trend analysis becomes unreliable and the very legislation that we pass to make the public safer is frustrated. We have already seen what happens when biological sex is replaced with self-declared gender identity. As has already been mentioned, in Scotland, Police Scotland permitted suspects’ sex to be recorded on the basis of self-identification, including in serious sexual offences. The consequences were predictable and serious: incoherent statistics, loss of public confidence and an inability to analyse male violence accurately. After sustained scrutiny, Police Scotland reversed that policy in October 2025 and confirmed that biological sex would be recorded, with transgender status noted separately where relevant. That reversal was driven by operational reality, not ideology, and it offers a clear lesson for England and Wales. Independent expert evidence reinforces this point. The Government-commissioned review led by Professor Alice Sullivan was unequivocal: sex should mean biological sex and, where gender identity is relevant, it should be recorded separately, not substituted. Similar conclusions have been reached by independent analysis examining the consequences of degraded data across public bodies. Once sex data is compromised, statistics become contested, safeguarding weakens and public trust is eroded. There are also real-world safeguarding implications. Ministry of Justice analysis shows that trans-identified male offenders exhibit offending patterns aligned with the male population, including for violent and sexual crimes. Recording such individuals as female underestimates male violence, artificially inflates female offending and distorts risk analysis. We have already seen the downstream consequences in the prison estate, where serious safeguarding failures led the Government to tighten allocation rules. Biological sex is a material risk factor; police data is upstream of all this and, if it is wrong at the point of arrest or charge, the entire system is compromised. There is a theme running through many of our debates today: good policing is inextricably linked to good data. The Government have acknowledged this. Biological sex is just one of the data variables that must be recorded for accurate policing, so I wholeheartedly support my noble friend’s amendment and I hope the Minister will, too.
