Question to the Home Office:

To ask the Secretary of State for the Home Department, how many allegations of discriminatory behaviour by police officers have been made in each police force in each of the last three years; and how many of those allegations were upheld.

Statistics on numbers of allegations made by the public against officers (including on discriminatory behaviour) are collated and published by the Independent Office for Police Conduct in their quarterly performance data. These include a breakdown for each force area, and are available on the IOPC’s website:
https://policeconduct.gov.uk/research-and-learning/statistics/complaints-statistics/your-local-police-force
Information on outcomes in relation to public complaints of discriminatory behaviour is not currently available. However, the IOPC have advised that they will write to the honourable member for Shipley

Information on internal allegations of discrimination made by officers and any subsequent disciplinary outcomes may be held by individual forces however such information is not held centrally by the Home Office.
