Civil Partnerships, Marriages and Deaths (Registration Etc.) Bill

My hon. Friend is perfectly entitled to her view, but I fundamentally disagree with it. I certainly would not wish to deny those potentially many thousands of couples on the basis of this costing about £3 million. She says there is no difference between civil partnership and marriage, and that it should not be treated any differently. In terms of status, that is right, but why is it that more than 80% of same-sex couples who have committed to a civil partnership do not think that they need to or want to convert that into a marriage? They think a civil partnership is different and more appropriate for them—why does she think they are wrong?
