I accept that point. There are genuine difficulties about the timing. If we look not just at the Iraq war, but at some of the other military actions over the past 10 years, we see that there have been quite long build-up periods. Choosing when there should be a vote is not simple. I would not pretend for one moment that it was. But we ought to give some thought to the mechanisms for determining the timing of the vote. That will be critical in getting a procedure that works properly—if we are going to have parliamentary involvement. I am not suggesting for one minute that I have a simple, easy answer, but it is a key point.
