'Jails within jails' to segregate extremist prisoners

Three specialist units are being built in high-security jails to separate extremist inmates from the rest of the prison population.The Government is creating the "jails within jails" in a bid to tackle radicalisation, and to stop convicts with dangerous Islamist or far-right ideologies from influencing their peers.In total, the centres will be able to accommodate up to 28 extremists - and the first unit at HMP Frankland in Durham is expected to be operational within weeks.
