Extremist Islamic hate literature is available on the bookshelves of British jails and distributed to inmates by Muslim chaplains, according to a leaked report.
A review into extremism in prisons found misogynistic and homophobic pamphlets and hate tracts endorsing the killing of apostates were available in chaplaincy rooms, the Times reported.
Hate literature and CDs were reportedly discovered in more than ten prisons in November.
A summary of the review, led by former prison governor Ian Acheson, was supposed to have been released last month but was postponed. The review was ordered by Michael Gove.
The report is also said to have found that chaplains at some jails encouraged inmates to raise money for Islamic charities linked to international terrorism.
Muslim chaplains, appointed by the Ministry of Justice, can earn up to £40,000. There are around 100 employed full time in prisons.
Around 1,000 prisoners in England and Wales have been identified as being extremists or vulnerable to radicalisation. Of the 12,328 Muslim prisoners, 131 are convicted Islamist terrorists.
Earlier this year it was suggested that all convicted Jihadi terrorists could be placed in a single top security prison in a measure designed to prevent them from spreading their propaganda to other inmates.
Policy for the past 50 years has been to disperse dangerous inmates around eight jails.
