Majid is a British activist, author, columnist and politician. He is the co-founder and chairman of Quilliam, a counter-extremism think tank that seeks to challenge the narratives of Islamist extremists. Majid is a former member of the radical Islamist group Hizb ut-Tahrir. This association led to his arrest in Egypt in December 2001, where he remained imprisoned until 2006. Reading books on human rights and interacting with Amnesty International, which adopted him as a prisoner of conscience, resulted in a change of heart. This led Nawaz to leave Hizb-ut-Tahrir in 2007, renounce his Islamist past and call for a "Secular Islam". He documented his life story in his Amazon bestselling autobiography Radical. Since then, he has risen to become a prominent critic of Islamism in the United Kingdom. He is a regular op-ed contributor, debater and public commenter, and has spoken from various international platforms including the TED conference. He presented his views on radicalisation in front of US Senate Committee and UK Home Affairs Committee in their respective inquiries on the roots of radical extremism.
