How do you solve a problem like Anjem Choudary?
Next month the Islamist preacher Anjem Choudary will be released from prison, having served just half of his five-and-a-half-year sentence. The Justice Secretary, Rory Stewart, echoed that verdict earlier this month, calling Choudary 'deeply pernicious' and a 'destabilizing influence'. His views remain the same; his status as a martyr - at least in the eyes of his followers - is assured; and his hatred of Britain is more ferocious than before. He will emerge as a greater menace than when he was locked up.
