Human Fertilisation and Embryology Bill [Lords]

I am afraid that I do not understand the hon. Gentleman's point, and I do not know which part of the Bill he is referring to. I therefore do not want to be drawn into a discussion, but hopefully the hon. Gentleman will have a chance to pursue the matter further. There are really only two questions to be asked. The first is whether the discrimination—or the measure—is justified. The research is clear and is summarised by the British Medical Association, which says that there is no evidence that children do badly in families of that kind. According to the BMA,"““Social research on children born to these families has given similar findings to those children born to solo mothers. Their emotional and psychological development is comparable to children born of donor insemination to two heterosexual parents. In fact, the second female parent often has greater parent-child interaction than do the fathers in the heterosexual couples.””" The reference for that quotation is one of those cited by the Minister—I know that the same briefing has been sent to all Members. Murray and Golombok made the results of their research very clear. They also looked into the question of solo mothers, and recognised the difference between different types of mothers on their own. Widows are different from young women who have been abandoned by the fathers of their children and who are living in poverty. Solo parents are often well-resourced, given that they often have to obtain private treatment. They often have established careers, and do not have partners. They are entirely different from families of the kind that the right hon. Member for Chingford and Woodford Green has examined in great detail during his trawls around the country.
