Human Fertilisation and Embryology Bill [Lords]

I understand my hon. Friend's point. I said that there would be a wide spectrum of circumstances and that cases would be different. One could equally argue that a child who had an elder sibling with a congenital disease that would lead to certain death, and who was not used for such a treatment, would suffer a bereavement that would result in an even greater psychological disadvantage. There is no easy answer to any of these problems and I do not pretend to have all the answers. However, I return to my previous point: I can foresee circumstances in which a young person would feel good about having played a part in the survival of an elder sibling.
