I hope that my hon. Friend will forgive me if I make some progress.
As it does not appear that there is a constituency that is in favour of the change, we do not know how many people would enter into such a commitment. The findings of a poll that was conducted by YouGov at the weekend suggested that the uptake would be relatively low. Given the number of cohabiting couples, we must start to consider what are the proper policy solutions.
In 2007, the Law Commission produced a set of proposals that would have imposed duties on cohabiting couples when it came to separation and their responsibilities for children. My hon. Friend—who I know has a fine record, having been a children’s Minister—did not mention that. According to the Law Commission,
“cohabitants have not made the distinctive legal and public commitment that marriage entails.”
The truth is that the arrangement into which they enter is completely different from the arrangement that we would create in respect of civil partnership. I think that more work needs to be done to assess the real level of demand and determine what are the right cohabiting policy solutions.
The second issue that I wish to raise was described by my hon. Friend the Member for Bristol North West (Charlotte Leslie) as the need to ensure symmetry. Let me point out that no symmetry will be created even if the Bill is passed, as I very much hope that it will be. If passed, it will be a huge step forward in allowing marriage for same-sex couples, but no symmetry will be created, because the principal Churches will not allow marriage for same-sex couples. The Church of England will not be allowed to do it, and the Catholic Church will choose not to do it. It is a false argument to suggest that a symmetry will be created, or that the Bill will create an asymmetry that it will be possible to correct by extending civil partnerships to a completely unquantified and unknown group of people.
Is it not the case that in a mad rush to put same-sex marriage on the statute book, the right hon. Gentleman is prepared to ditch and discard everyone else’s rights irrespective of the cost?
I have already said that I have no objection to the principle, but there is no evidence that there is a demand for the measure.
That brings me to the third point that I wish to make. We now have the prospect of achieving an incredibly important step forward for same-sex couples by introducing marriage for them, and I am very anxious about the possibility that that will be put at risk—I do not put it any more strongly than that—if we add to the Bill an uncertain and unquantified element for which there does not appear to be a genuine demand. I believe the other place may then add greater difficulty into the Bill than would otherwise be the case. It will have two issues to deal with, rather than one. I therefore urge all of good faith who support marriage for same-sex couples to be very cautious before supporting the amendment in question. Indeed, I urge them to oppose it, and to do the straightforward thing of agreeing to the review. I support the Opposition amendment to ensure that the review is immediate. Given the complexity of these issues, that is an eminently sensible way forward.
