An al-Qaeda terrorist involved in a plot to bomb London was taught how to be a stand-up COMIC at his top-security prison, The Sun can reveal.
Evil Zia Ul Haq was enrolled on an eight-day "comedy workshop" at Whitemoor jail, along with murderers and rapists.
An inquiry was launched today by the director of high security prisons to consider whether further action was needed, the Ministry of Justice said.
A spokeswoman added: "The director general of the National Offender Management Service is personally briefing governors from all prisons on the need to take account of the public acceptability test in relation to prison classes."
The 18 cons were given lessons in stand-up, comic drama, improvisation and scriptwriting.
