Human Fertilisation and Embryology Bill [Lords]

I am grateful for the hon. Gentleman's intervention, which relates to my next point. In his opening remarks, the right hon. Member for Chingford and Woodford Green (Mr. Duncan Smith) made assertions about behaviour in all families on the basis of evidence from families that had broken down. With no support or evidence, the right hon. Gentleman sought to advance the argument that the children whom we are discussing would suffer a certain fate. The evidence, however, is available. Social research from Murray, Golombok and Brewaeys shows that children of same-sex couples develop emotionally and psychologically in a similar way to children born of heterosexual donor-inseminated couples. What counts is the quality of parenting.
