My Lords, in relation to acts preparatory, the noble and learned Lord will know that we have never underestimated the difficulty of drafting proposals in relation to these matters which are sufficiently tight and which enable proper direction to be given in relation to the criminality involved. Even now, let me say plainly that I do not see it as an easy task. We have a proper regard in this country for the acuity of drafting because we know that citizens' liberty will be at stake. We do not make such provisions with anything other than the greatest of care.
In relation to intercept evidence, I assure the noble and learned Lord that we continue to consider that matter. That is something that I have made plain from this Dispatch Box on a number of occasions.
Section 54 of the Terrorism Act 2000 does not include training in the use of hazardous substances, as opposed to noxious substances. It is in order to cover all substances that we seek to extend the provision. There were a number of technical loopholes in the Terrorism Act 2000 that we now seek to close.
