Genetic Technology (Precision Breeding) Bill

Debate between Caroline Lucas and Katherine Fletcher

2nd reading
Wednesday 15th June 2022 Commons Chamber

[Caroline Lucas (Brighton, Pavilion) (Green)]

I believe that this is a flawed Bill—it is not strategic, it is not clear and it does not do what it says on the tin. Ministers breezily assert that it will deliver access to wonderful new markets, while failing to acknowledge that it actually risks hindering access to our closest significant market, the EU, as we create a divergent regime for regulating genome-edited products. As we have heard, consequences for trade with Northern Ireland are being ignored. With the Scottish and Welsh Governments currently taking a different approach from that of England, the Bill is a recipe for consumer confusion and significant operational difficulties for retailers across the UK.

These big questions are critical, but in the short time that I have, I shall spell out how the Bill falls down on some core principles that render it flawed and not fit for purpose. Those principles are scientific coherence and clarity, properly defined criteria—or the lack of them—and transparency.

On coherence and clarity, in its title and text the Bill uses the phrase “precision breeding”, yet that is neither a specific technology nor a scientific discipline. It is a marketing term: a vague colloquialism for a number of recently developed genetic engineering technologies, which do not form a coherent group of methods, and do not justify being called “precise”—not when the scientific literature contains reports of genetic technologies such as genome editing creating unexpected and unwanted mutations, genetic errors, altered proteins, and extensive deletions and complex rearrangements of DNA in plants. [Interruption.] I will not give way yet.

The Government give a nod to that uncertainty with their caveat that genetic editing of animals will not take place until animal protection can be safeguarded. Engineering the DNA of animals raises major animal welfare and ethical concerns. A wealth of problems are set out by the Nuffield Council on Bioethics report on gene-edited farm animals. As I understand it, there is nothing to prevent biotech-created disease resistance being used as a sticking-plaster for the intensive factory farming practices that are the underlying cause of disease emergence in the first place. That is why, given the current drafting, animals should be removed from the Bill’s scope, full stop.

[Katherine Fletcher]

Nature makes mistakes; that is how evolution comes about. So the mistakes that are reported in the literature are actually further evidence that such technologies effectively replicate a natural process. Does the hon. Lady agree?

[Caroline Lucas]

I thank the hon. Lady for her intervention. As has been said, she clearly has expertise, but I am looking at the scientific evidence that has been put before me, and it is being suggested that the mistakes that can be made in this area, especially when it comes to nature, appear very different from those that are seen in nature.

I move on to the principle of properly defined criteria. Using a term that lacks any proper definition looks like an attempt to obscure the full scope of the proposed deregulation. The terms “precision breeding” and gene editing help promote a particular narrative—that the process is just a simple “cut” or “tweak”. The Government are also at pains to stress that any changes might have occurred “naturally” and do not involve the insertion of transgenes—so-called “foreign” DNA.

I have read that this is to some extent smoke and mirrors. The Bill seeks to deregulate all manner of genetic manipulations, and genome editing can sometimes involve the insertion of foreign DNA. As I understand it, the argument is that in such cases the inserted DNA gets removed before the product goes to market. That may well be the intention; but by using poorly defined criteria in the title and wording of the Bill, the Government are asking us to pass bad legislation.
