My Lords, on 3 April, the Times reported that Islamist gangs had created gross dysfunction in HMP Frankland, in which a large number of convicted terrorists are held. Just nine days later, on 12 April, Abedi, the Manchester bomber, detained in the same Frankland prison, threw hot oil over a prison officer. Then, on 8 May, Rudakubana, the Southport killer, detained in HMP Belmarsh, threw boiling water over an officer there. Both those terrible attacks were by radical Islamists, in category A prisons. What steps will be taken to isolate such prisoners from access to such dangerous substances? Will tasers be issued in category A prisons, and when will stab vests be provided?
