This report presents results from the most extensive research of British Muslims ever conducted. The process produced an extremely rich dataset, formed by the results from over 3000 in-depth interviews allied to transcripts and notes from ten multi-participant focus groups. A random location, quota-based sampling approach was used within locations where the Muslim population accounts for at least 20% of the total population. The report outlines some of the most salient and interesting aspects of the results. It finds that British Muslims broadly share the same views as the rest of the population. Despite the greater religiosity and social conservatism of British Muslims, their life-styles are largely secular with only limited interest in sharia finance or separate religious education. However, the report also highlights a mentality of victimhood in Muslim communities and a belief in conspiracy theories about 9/11. It also finds that some of the best known organisations, such as the Muslim Council of Britain, have very little support among British Muslims. They are also much more comfortable than is commonly believed with government-led initiatives against radicalisation and almost half believe that Muslims should do more to combat extremism in their own communities.
