(BBC) A convicted terrorist was eight months into a deradicalisation programme when he tried to murder a prison guard.
Brusthom Ziamani, 25, was jailed for life after he and Baz Hockton, 26, attacked Neil Trundle at HMP Whitemoor in Cambridgeshire in January.
They were armed with makeshift weapons and wore fake suicide belts for the targeted attack.
The Prison Officers Association (POA) has called for a “fundamental review” of deradicalisation schemes.
The assault on Mr Trundle is the first terrorist attack to occur inside a British jail.
