My Lords, I must declare an interest in that much of the groundbreaking science of mitochondrial donation has happened at Newcastle University, where my wife also works, although in a different field. Also, some of the relevant work has taken place on the premises of the International Centre for Life in Newcastle, of which I am honorary president. I am also a fellow of the Academy of Medical Sciences.
I shall be as brief as I can. We have a duty to consider five simple questions. Is it legal? Is it safe? Is it necessary? Is it ethical? Is it rushed? It seems to me that, as the noble Lord, Lord Turnberg, said, we have clear evidence that it is legal for Parliament to enact these regulations. They are explicitly foreshadowed in the Human Fertilisation and Embryology Act 2008. They are not covered by the clinical trials directive. They are not eugenic, and therefore not in conflict with the EU Charter of Fundamental Rights.
Is it safe? We have heard that the safety and efficacy of both techniques have been established as far as is possible by exhaustive study, independent scrutiny and public consultation. The case of the Chinese example, as the noble Lord, Lord Patel, has said, is simply not relevant to this case. This was an obstetric disaster that happened to one woman and was a technique that was intended to cure infertility and had nothing to do with mitochondria anyway. As far as we can tell, the mitochondrial transplant element of that technique worked.
As for the infertility question, I have to say that I think my noble friend Lord Deben has misquoted a very distinguished scientist, Professor Robin Lovell-Badge. I was in the same meeting and I did not hear him say the words that the noble Lord said. He made the point that some techniques that are already legal and used
probably perpetuate some forms of infertility. We therefore already accept that some techniques that are used may produce children who lead very happy lives but will themselves require assisted reproduction.
Incidentally, I completely agree with my noble friend Lord Deben that we should not argue from authority, that the consensus of scientists may sometimes be wrong and that we should make up our own minds. As always in science, however, it is the evidence, not the existence of a consensus, that convinces me that this is efficacious and safe.
Is mitochondrial donation necessary? If there is one thing that we have learnt from 30 years of in vitro fertilisation, it is that adoption is not a full alternative to conception. Were we right to give women assisted reproduction so that they could have their own children? Yes. Millions of happy mothers bear witness to that.
Is pre-implantation genetic diagnosis an alternative in this case? Often it is not, because it is more likely, as we have heard from the noble Lord, Lord Patel, because of heteroplasmy, to produce an afflicted child. I was also surprised to hear the noble Lord, Lord Deben, say that the reason we are going ahead with the techniques of maternal spindle transfer and pronuclear transfer is “about money”. I just do not think that is the case. It is very clear, as we have heard from the noble Lord, Lord Patel, and others, that there are very good reasons to go ahead with both these techniques.
Is it ethical? We do not, in the 21st century, have the luxury of deciding these things in a theological way. If we block an advance of this kind and it turns out that it could have eliminated suffering safely, then it is on our consciences in a way that it would not have been 30 years ago, when we could do nothing. In losing our impotence, we also lose our innocence. In other countries, this decision would be up to the regulator already. Here, uniquely, we have explicitly said that Parliament should first decide whether the regulator can take such cases, which is what we are deciding today.
Once Parliament has decided that mitochondrial donation is not likely to be unsafe, and the HFEA has judged that it is safe, it should be up to families to decide whether they wish to use it. It would be unethical for the state to deny them that choice.
We may become the first country to do mitochondrial donation, but there is nothing wrong with that. Britain has been the first with most biological breakthroughs, from natural selection to the double helix, from monoclonal antibodies to in vitro fertilisation. In every case, we look back and see that we did more good than bad as a result.

In this House, we have been deluged with off-the-shelf emails from people overseas demanding that we support my noble friend Lord Deben’s amendment to stop so-called GM babies. However, I am afraid the senders have been misinformed, as the noble Lord, Lord Turnberg, said. Describing mitochondrial donation as producing GM babies or, indeed, three-parent babies is using phrases that are wildly misleading. You cannot call someone with 0.1% of their genes and 0.054% of their DNA donated from somebody else the child of three parents. That is a misuse of the English language.
The reason it is not genetic modification, as the term is understood by most people, is simple: this is therapeutic, not eugenic. It is germline only for female babies. As the noble Lord, Lord Patel, said, this is a dead end in males. I do not, however, hear the opponents arguing that we should license this technology for male babies, even though that would be perfectly logical if that is their real concern.
Finally, is it rushed? Far from being hurried, it has been under development for more than 30 years, under debate for 15 and under scrutiny for five. There is nothing slippery about this slope. There has been no rush. Now, however, that we have reached this stage there jolly well should be some reasonable haste on behalf of the women whose reproductive life is running out and who desperately want their own child, people such as Claire Wright, who is now 40 and who had to watch her son Jacob lose his smile on the way to a cruel death. Yes, there is understandable urgency. We would have to have very good reasons to argue that the ethical thing to do is to prolong her suffering and that of others like her. I cannot see those reasons.
