n. a hard-line extremist Islamic group in Great Britain who support bin Laden and other terrorist groups
Al-Muhajiroun (; The Emigrants) is a banned Salafi jihadi terrorist organisation that was based in Britain and which has been linked to international terrorism, homophobia and antisemitism. The group operated in the United Kingdom from 14 January 1986 until the British Government announced an intended ban in August 2005. The group became notorious for its September 2002 conference, "The Magnificent 19", praising the September 11, 2001 attacks. The group mutates periodically so as to evade the law; it then operates under aliases. It was proscribed under the UK Terrorism Act 2000 on 14 January 2010 together with four other organisations including Islam4UK, and again in 2014 as "Need4Khilafah".
Al-Muhajiroun has also run a Lahore safe house for visiting British Muslims. Michael Adebolajo, the man convicted of killing Lee Rigby in a terrorist attack in Woolwich, attended Al-Muhajiroun meetings and demonstrations.
