Question to the Ministry of Justice:

To ask the Secretary of State for Justice, if he will list the three most recent riots that took place in prisons or young offenders institutions.

‘Riot’ is not used as an incident classification. An incident in which two or more prisoners act together in defiance of a lawful instruction or against the requirements of the regime of the establishment is categorised as “concerted indiscipline”.

The number of concerted indiscipline incidents in the 12 months to 31 March 2026 is published in the HMPPS Annual Digest 2025-26. Data about incidents in the 12 months to 31 March 2027 are due for publication next year. The requested data are therefore exempt from disclosure, because they form part of a data set intended for future publication.
