Question to the Ministry of Justice:

To ask His Majesty's Government how many prisoners in Category A prisons are foreign nationals; and how many of the total prison population are undocumented migrants without proof of a UK visa or granted asylum.

As of 30 June 2025, 577 foreign national offenders were held in Category A prisons. The immigration status of individual foreign nationals is a matter for the Home Office, and the Ministry of Justice does not hold information in relation to it.

All foreign nationals given a custodial sentence are referred to the Home Office to consider whether they should be removed from the UK on account of their criminality or immigration status.
