Counter-Terrorism and Security Bill

I came somewhat late to the debate—for which I apologise—so I may have missed this. There is an issue about the counter-productive nature of control orders, as was, in terms of radicalising sections of the community, just as internment did with regard to the Irish community in Northern Ireland. Is there any estimate, or provisional estimate, of the scale of the use of TPIMs as envisaged in the Bill?
