I will live up to what the noble Lord, Lord True, expects and disappoint him. Not everyone was here in Committee, when this was discussed at greater length and there was an amendment to reduce the number—I think to four, or even to zero—so it was not as clear-cut then that the number should be increased. Indeed, the number six is not the full number of people who will necessarily always have to seek permission, because they have to seek permission at the point at which they marry. It could well include far more people. Someone who may not be heir to the Throne within the first six at any one point could be in that position by the time that they want to marry. It applies at the time of their marriage, so more people may well have to seek permission.
As we said when this was discussed at greater length in Committee, with more evidence given than perhaps all noble Lords have had a chance to read, we feel that this is not an exact science. We know that five were probably as many as were ever needed, so we thought that six gave a useful additional margin.
We certainly do not think that it is sensible to involve an unnecessarily large number of people in having to seek permission of the Crown in order to marry when they have no realistic possibility of inheriting the Throne. We do not know on what grounds a monarch would debar someone from a particular marriage if it was not about religion, although one noble Lord suggested that. We do not know what sort of reasons a couple would have to consider when deciding whether to go ahead with the marriage and give up their place in line. It seems to us strange to put a young couple through that when there is no good reason for doing so.
I should add that although this was not in the original Perth agreement, it is part of the agreement that has been discussed with all the other countries, with all the hard work done on everyone’s behalf by New Zealand. It would need an enormous amount of unscrambling to change the number now when it has been discussed at great length. I am sure that it is in no way the intention behind the amendment that it should be wrecking or delaying. However, I fear that changing the number from six would have that effect. I am sure that we would not want to risk the other really important parts of the Bill, the two bits that the whole House strongly supports—the succession to the Crown of the first born, should it be a woman, and the ability of someone in line to the Throne to marry a Catholic—by delay. We support the continuation of the Bill as it stands.
