Question to the Home Office:
To ask the Secretary of State for the Home Department, how many DNA profiles of prisoners still serving a sentence have not yet been added to the DNA database.
It has been standard practice for the police to take DNA profiles from all persons arrested for a recordable offence for many years. If the person is then convicted, their DNA profile is retained indefinitely. The proportion of prisoners whose profiles are not on the database is therefore likely to be very small.
