(BBC) Limits have been placed on the amount of books convicted terrorists in England and Wales can keep in their prison cells.
Extremists will also now be banned from taking a “leading role” in religious services under the new measures.
It follows a 2022 report which raised concerns about radicalisation and Islamist gangs in prisons.
New Justice Secretary Alex Chalk said the changes would stop terrorists advancing “their own sinister agenda.”
Those in custody convicted of terrorism — about 200 people — will be limited to two medium-sized boxes of books that must weigh no more than 15kg.
