Part 2 of the Terrorism Act 2000 (c. 11) makes provision about proscribed organisations (including setting out offences in relation to such organisations in sections 11 to 13). An organisation is proscribed if it is listed in Schedule 2 to that Act or, in most cases, if it operates under the same name as an organisation so listed (section 3(1)). Article 2 of this Order adds four organisations (with known aliases included in parentheses) to the list in that Schedule. Article 3 of this Order removes an organisation from the list in Schedule 2, so that it is no longer proscribed.
