Terrorism (Northern Ireland) Bill

If, as the hon. Member for Glasgow, South (Mr. Harris) says, it will never be possible for us to be absolutely certain that the IRA has decommissioned all its weaponry and that, therefore, we are left with having to make a working assumption at some stage, does not that make it all the more necessary that we tighten the requirement in relation to paramilitary activity and criminal activity to be absolutely certain over a longer period, because the IRA has bowled short in terms of the transparency that was required on decommissioning?
