It is a Sunday night in London's East End and the self-styled "most hated man in Britain" is holding court, reveling in his vision of a Taliban victory over America and a world under Islamic Shariah law.

"There are many battlefields," he says calmly into a microphone. "There's a battlefield outside 10 Downing Street [home to Britain's prime minister] and in the mountains of the Tora Bora [in Afghanistan]."
