My Lords, I rise briefly to support what has been said by the noble and right reverend Lord and to make two precise points. The first is that the original amendment provided for a period of nine months, which is too short. As we know from many experiences, there is a complexity about elections and everything does not surface as quickly as that. It is sensible and important, if we are to have a review, that it should take into account all that has happened during an election—some of that will be local and some national—and that it is allowed to take note of all the propositions that have arisen. That is because a review that comes too early is one that might well get it wrong.
My second point is the importance of the sunset clause, as has been mentioned by the noble and right reverend Lord. I am afraid that I am a little cynical about government reviews. In my experience they do not always happen, sometimes they happen with some very odd persons being involved in them, and sometimes they just disappear into thin air. The great thing about a sunset clause is that it concentrates the mind of Government wonderfully. It is like a wicket in cricket. It makes it possible to consider very carefully what is at stake. I therefore strongly support the noble and right reverend Lord in calling for a sunset clause to be linked to the review because the sunset clause makes it certain that the review will happen and be taken seriously. The Government of the day will then have to consider in detail, in the way that the noble and right reverend Lord has asked for, many aspects of this very complex law.
