Asim Siddiqui, the chairman of the City Circle, has written an insightful article, "Who needs a caliphate?", on how the failure of Islamism to bring tangible social or economic benefits to Islamic societies may mean that Muslims will increasingly reject such ideologies in favour of greater democracy and individual freedom.
