“We understand Derbyshire Constabulary authorised the use of Microsoft Copilot for officers in May 2025, with guidance on how it could be used to aid productivity in drafting reports and summarising information. There were conditions on its use, including that no operational, sensitive or personal data should be inputted to AI.
“Our investigation will analyse the officer’s use of Copilot between May last year and June this year and assess if there are any potential breaches of police professional standards.”
