Excerpt:
Sauntering along a London street after serving just half of a five-and-a-half-year jail sentence, this is the British hate preacher who inspired an Isis executioner.
He is Mohammed Mizanur Rahman, 36, pictured below for the first time since his release from maximum-security Full Sutton prison in North Yorkshire, where he served little more than two years of his sentence.
Rahman, seen near his family home in Palmers Green, North London, was arrested after publicly pledging his allegiance to the Islamic State group soon after it declared a so-called caliphate in Syria in June 2014.
Rahman is believed to have radicalised Siddhartha Dhar, a childhood friend from his neighbourhood, converting him from Hinduism to Islam and introducing him to the banned extremist group Al-Muhajiroun (ALM).
