Speaking for the first time since his release from prison for trying to bring Sharia Law to the streets of London, was Jordan Horner, who has taken the Islamic name Jamaal Uddin.
In December 2012, Horner was filmed at a protest alongside Michael Adebowale who, five months later, murdered soldier Lee Rigby in Woolwich.
He claimed he had converted other prisoners during his time in prison.
Mr Horner said to BBC Panorama:
The prison officers witnessed people become Muslim. In front of them I was giving them what we call Shahada, an invitation and acceptance of Islam.
They were becoming Muslim in front of the prison officers and they felt sort of powerless.
They said I was trying to divide Muslims from non-Muslims, trying to get them to follow an extreme version of Islam.
He added that in less than a year he was transferred between three different jails in an effort to disrupt his activities.
