Q Thank you for making that extremely clear. I am sure that the Committee will pay close attention to the advice being given to us through you by the security services. I have one more question on TPIMs, relating to the current two-year expiry date and the proposal to make them annually renewable. They will not be indefinite unless the threat is indefinite. Do the security services for whom you speak see a threat to the public as a consequence of the gaps that we have heard Mr Hall describe: the 12-month gap in one case and the 16-month gap in the other?
