Question to the Ministry of Justice:

To ask His Majesty's Government how many prison officers in long term and high security estate prisons have been assaulted in each of (1) close supervision centres, (2) separation centres, and (3) segregation units from 7 January 2025 to date.

Assaults statistics, including assault on staff incidents by prison, are published quarterly. These were last published in January 2026, covering data up to September 2025: Safety in custody: quarterly update to September 2025 - GOV.UK.

Centrally collated data on assaults does not go into the depth of specific residential location requested, meaning the data requested could only be provided at disproportionate cost.
