Terrorism Act 2000 (Proscribed Organisations) (Amendment) Order 2006

My Lords, I will not attempt to name any of the four organisations, because I am sure I would get them wrong. I say at once that I have no difficulty at all with the third and fourth of the organisations. I have questions about the first two organisations. First, could they in fact have been proscribed under the existing law without having resort to the 2006 Act? Secondly, could the Minister give us some indication of the membership of the first two organisations in the United Kingdom? How many people will be affected by the proscription? Thirdly, she has not mentioned Hizb ut-Tahrir. There was a strong rumour at one stage that it would be proscribed under the new legislation. I am very glad if it be the fact that it has not been. Has a decision been taken not to proscribe Hizb ut-Tahrir?
