Mitochondrial Replacement (Public Safety)

Debate between Frank Dobson and Robert Flello

Monday 1st September 2014 Commons Chamber

[Robert Flello (Stoke-on-Trent South) (Lab)]

I thank the hon. Member for Congleton (Fiona Bruce) for securing this important debate. Some in this House are in favour of the treatment and oppose the motion, whereas others, like me, support the motion and oppose the procedure. The important thing is to have the debate and to put down a marker, and I hope that the Government do not try to rush these things through, as I believe they originally intended.

[Frank Dobson]

Consultation on this started in 2003. If this is a rush, how would my hon. Friend describe something that was slow?

[Robert Flello]

I am grateful to my right hon. Friend for that. I have been in this House since 2005 and this is the first debate I have had here on this matter, even though the consultation may have started in 2003. I will return to the issue of the consultation shortly, if I am able to do so in the four minutes and 10 seconds remaining to me.

There is no doubt that this disease affects many children—I believe the figure is one in 6,500—and has some horrendous and devastating consequences. However, the chief medical officer seems to believe that perhaps 10 lives a year might be changed as a result of this treatment. That is absolutely important for the 10 people involved and their families, but my understanding of the science is that it is very hard for the researchers to know who those 10 people might be and how to decide which children might benefit and which might not.

I agree with a number of speakers who say that two issues are involved. I have grave concerns about this from not only a moral, ethical point of view, but a public safety point of view. Whatever someone’s position on mitochondrial transfer, I am sure we must all agree that we cannot authorise new research techniques that are unsafe or might be unsafe. In this context “unsafe” does not only mean that procedures may not work; it means that they may result in disabilities and illnesses. To put it crudely, there is every possibility that we could be legislating to allow techniques that could cause damaged embryos, resulting in further damaged children. That is not spin; it is a reasonable assumption based on the available data. Newcastle university’s own paper concluded that, compared with control experiments, 50% fewer eggs fertilised through pronuclear transfer reached the blastocyst stage—in other words, pronuclear transfer is twice as likely to cause the embryos to fail. No further work was conducted on why so many of these embryos developed abnormally, despite consistent calls from concerned scientists.

Based on the available data, therefore, we cannot rule out the possibility that these techniques could cause the people born as a result to have illnesses or disabilities. The Government have a responsibility, as we all do, to avoid such eventualities, and we cannot take that lightly. We might not know the result for many generations. We might not know whether some damaged has been caused until three, four or five generations later. We simply cannot know that. Indeed, in a conversation I had with an hon. Friend in this House not a few hours ago there was talk of how science is about probabilities and risk; it is not fact but about what may or may not happen.
