Given that there are 3.2 million cohabiting opposite-sex couples, it is a very small proportion of those who might be affected, so this is unfinished business. More than 80,000 people have signed a petition in favour of the change, and that is a small indication of the demand that exists.
There are three main rationales for supporting the measure. First, it will correct the unintended but glaring inequality that results from the Marriage (Same Sex Couples) Act, whereby same-sex couples are entitled to continue in a civil partnership, take up a civil partnership or enjoy the recent extension of marriage while opposite-sex couples have only the single option of conventional marriage, albeit by a larger range of religious institutions. That is not fair, and it gives rise to an inequality in an Act that was billed as promoting equality.
Secondly, a positive reason for pushing forward with the Bill is family stability. As a former children’s Minister, that has always been at the top of my priority list. According to the latest estimate, there are some 3.2 million cohabiting opposite-sex couples in this country. That is more than 4,900 couples per parliamentary constituency, and it is about double the figure that was reported just 15 years ago. Those couples are responsible for more than 2 million children. Some 53% of birth registrations are to married parents, but about a third are to unmarried parents who are living together.
Cohabitation is the fastest growing form of family in this country, whether we like it or not. We need to recognise that our society is changing and we need to adapt in order to promote family stability, in whatever form, to provide a continuum that gives children the best and most stable start in life.
