Question to the Ministry of Justice:

To ask Her Majesty's Government how many individuals are currently serving custodial sentences for terrorist offences in the United Kingdom; and which prisons are used for confining such persons.

As reported in the latest statistics released on gov.uk, there were 184 persons serving custodial sentences for terrorist offences in Great Britain (as of 31 December 2020). A further 25 were being held on remand, ahead of trial or sentencing. Those in custody are assessed according to their individual risk and rehabilitation needs and are held in various prisons across the estate. We do not disclose operational detail regarding the location of all terrorist offenders in prison.

Data detailing the number of people serving custodial sentences for terrorist offences is available at Gov.uk. You can access this information here:
