This booklet is the result of the First International Conference on Radicalisation and Political Violence, which took place in London on 17-18 January 2008. The purpose of the conference was to bring together policymakers, senior practitioners and leading experts, and provide them with an opportunity to exchange and develop their ideas on how best to counter the growth of radicalisation and political violence. The Perspectives on Radicalisation and Political Violence booklet contains papers concerning the thoughts developed – and conclusions reached – by the seven expert working groups during the conference.
