The organisation and its activities have been condemned by larger British Muslim groups such as the Muslim Council of Britain and similar groups which represent the majority of Islam in the United Kingdom. In the United Kingdom, "Al-Muhajiroun" is the most notorious of the domestic Salafi-jihadist groups and its public spokesman Anjem Choudary has significant name recognition; it is considered more radical than its initial parent organisation the "Hizb ut-Tahrir", whose British-based branch does not advocate violence against the United Kingdom and thus has not been proscribed. Individual members of "Al-Muhajiroun" have been implicated in a number of terrorist attacks, including the murder of Lee Rigby (Michael Adebolajo and Michael Adebowale) and the 2017 London Bridge attack (Khuram Butt). Some members, such as Zacarias Moussaoui, have been implicated in controversies surrounding "Al-Qaeda". It has also operated a Lahore safe house for visiting radicals. Another member, Siddhartha Dhar, became an executioner for the Islamic State of Iraq and the Levant (ISIL).
