Islam appears to hold a strange fascination for white British women who are converting to it in large numbers. Of an estimated 50,000 or so white Britons who convert to Islam every year, some two-thirds are thought to be women. Most of them are independent career women — bankers, doctors, broadcasters — who know what they are doing, and often do so in the face of opposition from family and friends. High profile converts include Lauren Booth, sister-in-law of former Prime Minister Tony Blair, well-known journalist Yvonne Ridley and MTV presenter Kristiane Backer.
