Genetic Technology (Precision Breeding) Bill

Caroline Lucas Excerpts

2nd reading
Wednesday 15th June 2022 Commons Chamber

[The Secretary of State for Environment, Food and Rural Affairs (George Eustice)]

I beg to move, that the Bill be now read a Second time.

The UK is home to some of the world’s best agricultural research facilities. For some 70 years, plant breeders have used chemical and radiation treatments to generate random mutations in genes, in the hope that these might provide traits that are useful for plant breeding. For decades we have had F1—filial 1—hybrid breeding techniques, which were designed to create far greater genetic consistency in plant varieties that are grown commercially.

Precision breeding techniques such as gene editing are really a natural evolution of conventional approaches to plant breeding. They are simply a modern way of creating more targeted and predictable changes to DNA within a species than would have been possible using induced mutagenesis or natural breeding. They result in nothing that could not occur through natural breeding processes. In that sense, precision breeding techniques are distinct from genetic modification, which can involve moving genes across species boundaries. It is the recognition of this difference that is the reason for this Bill today.

In 2018, the European Court of Justice ruled that all gene-edited organisms should be legally regulated as genetically modified organisms. That has hampered our ability to take advantage of precision breeding techniques and of the clear opportunity to help the environment and food producers.

The UK Government disagreed with that 2018 judgment from the perspective of science. Now that we are outside the European Union we are free to consider what a consistent, coherent and science-based policy looks like. What we really need to achieve as we address today’s challenges is a fusion of the traditional principles of good farm husbandry with some of the best technology available to us in the 21st century.

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

The Secretary of State keeps using this language about precision breeding, but he will know that that is neither a specific technology nor a scientific principle. It relies on the creation of a hypothetical class of GMOs that could have occurred naturally. He will know that there is opposition to that definition from everyone from the environmental non-governmental organisations right through to the Nuffield Council on Bioethics and to the Roslin Institute. Given that level of disagreement about the very principles of how he is framing this Bill, will he take it away and look at it again?

[George Eustice]

We have considered these matters in great depth. We ran a consultation. The overwhelming view of scientists are that these precision-breeding techniques, which do not achieve or do anything that could not be achieved through natural breeding processes, are not in fact GMOs. That is our view. That is why we are bringing this Bill forward today. As the hon. Lady knows, there will no doubt be a debate about these matters in both Houses as the Bill progresses.

Precision breeding techniques give us the ability to produce plant varieties with particular traits far more efficiently than was ever possible with conventional breeding. This opens up huge opportunities for our farmers and growers to produce nutritious food with a lower environmental impact.

Precision breeding techniques can improve crop resistance to diseases, reduce the need for pesticides, increase crop yields, improve resistance to climate change, promote drought resistance and reduce the need for fertilisers.

I think consumers want to see fewer pesticides in their food, and technologies such as this open the door for us to achieve that. As part of the notification process that I will come on to describe, we will ensure that there is transparency and that any seed that is marketed is listed in a transparent way. The Food Standards Agency will also conduct a very thorough and comprehensive assessment of any food safety issues. I think that will give people the reassurance they need.

Returning to some other examples of crops, UK Research and Innovation funded a study that has identified promising sources of genetic resistance to virus yellows in sugar beet, a group of viruses that can cause severe yield losses of up to 50% and are at the heart of the controversy around the use of neonicotinoids in sugar beet. Introducing resistance to virus yellows will reduce the need for pesticides, boost our food security and reduce costs to our sugar beet producers.

With food security high on the agenda, we also have the ability to develop wheat that is more resilient to climate change, helping successfully to grow a crop that 2.5 billion people are dependent on globally. Researchers at the John Innes Centre in Norwich have used gene editing techniques to identify a key gene in wheat that can be used to introduce traits such as heat resilience, while maintaining high yields.

These technologies also have potential to improve the health and welfare of animals, as some of my hon. Friends have mentioned. Research in farmed animals is already leading to the development of animals that have increased resistance to some devastating diseases. For instance, the Roslin Institute and Genus have developed gene-edited pigs with natural resistance to porcine reproductive and respiratory syndrome, a disease that causes mortality and major welfare issues in pig populations globally.

I turn now to the contents of the Bill. It will focus on four key areas. First, we will remove precision-bred plants and animals from the regulatory requirements applicable to the environmental release and marketing of genetically modified organisms. That will remove the necessity of adhering to the onerous regulations imposed by the European Union for plants and animals that could also have been produced through traditional breeding. The Bill does that in part 1.

[Caroline Lucas]

The Secretary of State will know that section 20 of the Environment Act 2021 requires him to be able to affirm that this Bill does not weaken any existing environmental protections. Given that he has more or less just said that it precisely does, because it will weaken the EU legislation that we were following and will erode the existing regulatory system, how can he then sign section 20 in good faith?

[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.

[Sir Robert Goodwill]

Is it the case that, if the EU were to allow this technology to go ahead, the hon. Lady would, like the SNP, embrace it?

[Caroline Lucas]

I am not making a blanket statement in that way. I am saying that if a whole load more safeguards were built into the Bill and if it were not based on a set of definitions that are being criticised by the scientific community, I would have rather more confidence in it than I do right now.

As we have heard, several learned organisations have challenged the Government’s creation of this hypothetical class of GMOs that could have “occurred naturally” or could have been created using traditional breeding. The Institute of Food Science & Technology has called the approach “overly simplistic”, and the Nuffield Council on Bioethics was

“not convinced that this is either the most proper or most popular framing”.

The Roslin Institute found it “exceptionally challenging”, while the Royal Society of Biology said:

“No clarity can be achieved using this principle—we would not recommend using it as the basis for regulation.”

In response to last year’s public consultation, there was a clear view that this is a fundamentally flawed and unscientific basis for regulation.

Turning to transparency, there are no provisions in the Bill for the labelling of genetically engineered or so-called precision-bred food, despite this being what a majority of the public want, as the Government consultation made clear. In that consultation, 85% wanted genetic technologies used in farming to continue to be regulated in the same way as other GMOs. There are significant concerns over the commercial drivers of genome editing in farmed animals, for example. This makes labelling really important, not least if Ministers want citizen and market trust, and buy-in to any new regulatory regime. The public register idea is welcome, but it needs to be accessible as well as comprehensive, and it should include all genetic engineering events and organisms used in UK agriculture. Reduced data collection is worrying. Data that is not collected cannot be analysed. Ministers are simply assuming that risks are non-existent or vanishingly slight, but there is nothing scientific about such wishful thinking.

In conclusion, we need a national conversation. Regulation and innovation need not be at odds, but products of agricultural genetic engineering, including newer techniques, should be subject to a robust and transparent regulatory and governance framework. This must include a strong traceability and labelling scheme that protects the interests of organic farms and allows consumers to make a choice in the supermarket. This legislation lets down consumers, farmers, the environment and animals. Rushing ahead with a badly conceived and designed Bill because the Government are simply desperate to claim some kind of success on post-Brexit deregulation is unacceptable, and I urge them to bring back something better.
