My Lords, I would like to say a few words about Amendment 17, which I believe is grouped with this one. That is a slightly separate point, if I may say so. I am picking up the point that my noble friend Lord Northbrook has made, that the parliamentary approval process in many of the Commonwealth countries includes a referendum and is over and above whatever Ministers may have agreed over lunch, as my noble friend Lord Forsyth put it. The fact is that parliamentary approval is required in most, if not all, the Commonwealth countries concerned, and in some of them a referendum is also required. Presumably that cannot be done
overnight, so it would be better if the Bill came into force when all the Commonwealth countries had consented to it.
We have a problem if some of the countries approve and some do not. You would not have to think too tortuously to conceive of a situation at some future point where the late sovereign’s eldest child in one country was to be their head of state and the second child, who was a boy, was head of state of another. That is clearly absurd, so we need to speak with one voice on this matter as far as the Commonwealth is concerned. It might therefore be best to wait until they have all agreed.
