Excerpt:
Counter-terror chiefs have taken steps to prevent a banned organisation - which once praised the 9/11 attacks - circumvent the law by changing its name.
Alternative names for proscribed organisation Al-Muhajiroun, which once held a conference called The Magnificent 19 to praise the terrorists who attacked the Twin Towers in New York in 2001, have been covered by a new banning order.
More recently, it emerged Michael Adebolajo, the man convicted of murdering Fusilier Lee Rigby in a broad daylight attack in Woolwich, attended Al-Muhajiroun meetings and demonstrations.
