Human Fertilisation and Embryology

Debate between Edward Leigh and Lord Willetts

Tuesday 3rd February 2015 Commons Chamber

[Mr David Willetts (Havant) (Con)]

I apologise to you, Mr Speaker, and to the House for missing the opening speech in the debate. Nevertheless, I was keen to speak because I think that the proposals before us today would tackle a real human need. There are parents who are currently bringing into the world children with a horrible disease and the suffering is made more acute by the fact that now, for the first time, prospective parents know that they could be doing this procedure and they therefore face the dilemma of whether or not to have children.

I realise that there are important objections. My hon. Friend the Member for Congleton (Fiona Bruce) put forward the ethical objection. I fully understand the fact that our benefit from this treatment does not of itself overcome the ethical issues, which are crucial. The red line to which she referred is, I think, a red line over which we have designer babies and change the DNA that makes the character of a person. I am persuaded by the scientific evidence that the mitochondria is not part of the core DNA that does that. In the previous debates and the previous legislation, it was absolutely clear that the red line that the House was trying to set was one that stopped the changing of human nature, and we do not cross it today.

[Sir Edward Leigh]

But it can be inherited.

[Mr Willetts]

It is absolutely true that mitochondria can be inherited through the mother, but it does not change the character of the baby.

Secondly, let me consider the health and safety objection. Sometimes that objection is being used as a cover for what is really an underlying objection in principle. The scientists say, with typical caution and care, that there is no evidence that this is unsafe. It is true that nobody can have 100% certainty about that, but there have been 15 years of research and seven years of scrutiny, including by various scientific bodies and ones promoted under this Government, and so far no one has been able to come up with a concrete and powerful objection that suggests that the process is unsafe. It is right for us today to be considering moving on to the next step.
