Genetic Technology (Precision Breeding) Bill

Debate between Baroness Bennett of Manor Castle and Lord Winston

Committee stage
Monday 12th December 2022 Lords Chamber

[Baroness Bennett of Manor Castle (GP)]

My Lords, it is a great pleasure to follow the noble Lord, Lord Winston, and, indeed, our very acute Committee chair. I will speak to my Amendments 11 and 86 in this group. It is a great pleasure to follow the House’s acknowledged expert, who set out very clearly the major problems with this Bill and, indirectly, made the arguments for the two amendments I am presenting here. It is perhaps worth starting with my Amendment 86, which amends the Short Title of the Bill, leaving out “Precision Breeding” and inserting “Genome Editing”. I am very happy to debate whether that should be “gene editing” or whatever, but I think the noble Lord, Lord Winston, clearly set out the reasons why we should not be debating a Bill called “Precision Breeding”. As he said, there is no such thing as precision in biology.

There are many areas of science in which “precision” is appropriate and extremely useful. We think about elements of physics and mechanical engineering, say, and talk about going down to millimetres, micrometres, nanometres. We can look at how those might change when the temperature changes, for example. All of those things will be eminently, entirely predictable. That is true of physical properties, but it is not true of biological properties, as the noble Lord, Lord Winston, clearly set out.

I covered this issue extensively at Second Reading, so I am not going to go into it at great length, but essentially, precision breeding is an advertising slogan; it is not a legal description. I do not believe that an advertising slogan should have a place in the title of a Bill. Interestingly, when it was put to me that I should seek to amend the Short Title, a technical expert said to me, “You will never get that through the Clerks”. In fact, it went through without a murmur. I think there is a real awareness that this Bill is not properly titled.

[Lord Winston (Lab)]

On a point of information, the noble Baroness was a great deal luckier with the Clerks than I was, as I tried the same tactic and was told quite firmly that I could not do that.

[Baroness Bennett of Manor Castle (GP)]

I thank the noble Lord for his intervention. I do not know how that happened, but I think I might take that as a seconding of my Amendment 86. Noble Lords might say that it is only the title and it does not matter, but it is how people will identify the Bill.

I am going to refer a number of times to a Defra press release, dated 29 September 2021, which, all the way through, refers to “gene editing”. That is what it is telling people the Bill is about, drawing a very clear distinction, as it sees it, between gene editing and genetically modified organisms, an issue I will return to shortly. That is the case for amending the Short Title of the Bill. What we are talking about is not precision; it is not marked by exactness, and there are real problems if the Bill is not named clearly.

I come to something that is arguably very significant and considerably more impactful in the nature of the Bill. This is my Amendment 11, which would exclude the use of exogenous genetic material in the creation of, or remaining in, so-called precision-bred organisms. Here I need to venture into the depths of this a little, I am afraid; I apologise to the Committee for that. If we look at many of the definitions that describe gene editing, we see that they say this is simply removing genes from an organism or adding genes from a different variety of the same organism.

That is different from genetically modified organisms. The noble Lord, Lord Winston, suggested that, 30 years ago, when GMOs were being debated, they got an undeserved bad name. But look at some of the things that have been done with GMOs: for example, a salmon that combines the genes from three different types of fish and grows unnaturally fast, reaching adult size twice as fast as its wild relative, to be released into the environment with obvious and potentially massive impacts; or, perhaps even more indefensible, the transgenic zebrafish, bred with genes from jellyfish or coral, which give them a glowing effect under certain light conditions. These genetically engineered animals were popular in aquariums and have now escaped into the natural environment, with effects we have yet to understand.

We are being reassured that gene editing is not like that; that it is a different kind of thing. Certainly, that is what the Defra press release of 29 September, which I referred to earlier, said in the name of George Eustice, the Minister:

“Gene editing is different from genetic modification, because it does not result in the introduction of DNA from other species”.


That is what the public is being told by the department.

We are going to hear in this debate a great deal about CRISPR, and I shall say this only once: CRISPR stands for “clustered regularly interspaced short palindromic repeats”. This is the hallmark of a bacterial defence system which forms the basis of genome editing technology. It was first discovered in archaea, a branch of the tree of life that was itself discovered only in 1977—we are talking about very recent science here. The clue is in the description. This is using the bacterial system. The key element of gene editing is the insertion of genetic material from bacteria. That material may or may not be fully removed at some point in the organism’s development, and, as the noble Lord, Lord Winston, set out very clearly, once we put something in, we do not necessarily understand what impact there might be in the current generation, or potentially in future generations.

I am going to borrow and excellent phrase from the joint Soil Association, Friends of the Earth and GM Freeze briefing on the Bill: it says that the genome is

“more like an ecosystem than a codebook.”

Personally, I tend to say that DNA is not a machine blueprint, because that is the metaphor—the idea of animals as machines—that dates back to the philosopher René Descartes, who has a lot to answer for and still dominates far too much of our discussion. We do not have the understanding of how biology and biological systems work. We think about them as machines and they are absolutely, definitively not.

This matters because mixing species, which is what we are doing here with gene editing, is not something that generally happens in nature. Certainly, there is horizontal gene transfer—which is of great concern in the area of antimicrobial resistance, an issue that I do a great deal of work on—but that is a far more limited occurrence and occurs mostly within kingdoms of living things rather than across different kingdoms of living things, which is what we are doing here. My Amendment 11, saying that we cannot introduce genetic material from other species, is doing only what the Government, in their own information about the Bill, say they want to do. That is why I believe we should have Amendment 11.

[Baroness Bennett of Manor Castle (GP)]

I thank the Minister for his answer and thank everyone who contributed to what has been a very rich, full and very informed debate. I am going to deal first with the structural questions just raised by the noble Baronesses, Lady Hayman of Ullock and Lady Jones of Whitchurch.

We again have this problem that we have to wait for the regulations and trust the Government. I appreciate that the Minister was doing his best to persuade us, and I felt that he really wanted the opportunity to have a PowerPoint presentation here to show us a slide of his flowchart. But this is all about taking it on trust. Almost certainly, in the timeframe the Minister referred to, we are talking of not the same Government implementing this—I am not casting any aspersions on who the next Government might be—and the noble Lord not being in a position to guarantee what will happen in the future. We are left with this uncertainty and it not being clear. We know that tomorrow will test your Lordships’ House on just how much it is prepared to stand up against regulations. We shall see what happens then.

The Minister responded to me on the standards of what I call factory farming. He said that there is already legislation on this, but I say that that legislation is grossly inadequate and that we have huge disease problems because of that. Tightening up animal welfare regulations and regulations for housing animals in this country would greatly reduce the need to deal with problems of disease.

It is interesting that the Minister also said, perhaps a couple of times, that including animals is about making the UK the best place to conduct research. I come back to the point I made on an earlier group about whether this Bill is for animal welfare, food security for farmers, or for our biotechnology industry. It appears that we are hearing that it is for the biotechnology industry.

I am not going to run through all the contributions, because the noble Baronesses, Lady Parminter and Lady Hayman, have already provided us with a good summary, but I will draw together the responses from the Minister and a number of others, including the noble Lords, Lord Trees and Lord Cameron of Dillington. There have been suggestions about tackling disease, but we are talking about ecological niches here. Let us say you produce pigs that are entirely resistant to a particular disease; you are producing resistance to one species or one threat. You are very unlikely to produce widespread resistance, so you are opening up an ecological niche for another disease to come in, if you keep animals in conditions that allow that to happen.

We can take a practical example from what is happening in human society at this moment. Over many centuries, human societies have had conditions that have allowed the spread of a wide range of respiratory diseases.

[Lord Winston (Lab)]

I am grateful to the noble Baroness for giving way. Does she not agree with me that we have been somewhat dismissive in this debate of the use of vaccines? Surely one of the ways to look at this with more intensity, and perhaps more money, is to look at more vaccines not just for human health but for animal health. At the moment, the research there is nothing like as much as it is for humans.

[Baroness Bennett of Manor Castle (GP)]

I thank the noble Lord for his intervention and agree, although we know that animals kept in good conditions of husbandry are much less susceptible to disease. My first approach is to keep animals in conditions where they are not susceptible to disease, and then you do not need to go to the expense and effort of developing vaccines or using antibiotics, which have the issues with resistance that were raised by the noble Lord, Lord Cameron.

I was talking about respiratory viruses. Our population is threatened now by not just Covid-19 but a number of other coronaviruses that have long been causing respiratory diseases in humans. We are threatened by rhinoviruses and by flus, all because of conditions that make us prone to respiratory illnesses spreading. Tackling just one of those, as we have done with the Covid-19 vaccine that the noble Lord just referred to, with great effect, does not mean that we will stop all those other forms of respiratory illness.

That has covered the main points. I want to come back to the amendment from the noble Lord, Lord Winston, which raises some interesting points on great apes. I would extend this to all simians or monkeys. I ask your Lordships’ House to consider whether we actually want to be gene editing great apes or monkeys.

The point about equines is also very interesting when we think about horseracing and the enormous amount of money and the possibly shady characters involved in it. Whether we really want to see gene-editing in racehorses leads us into the companion animals question. It is a real area of concern. On that, the noble Lord, Lord Trees, referred to brachycephalic breeds that are identified as a problem area. If the breed societies were to say that they were going to create really rigid rules and change their definition of what those breeds are supposed to look like, that would be another way, a kind of husbandry way, of tackling the issue.

I will of course withdraw the amendment at this stage, but before I do that, I want to ask the Minister a question. Following on from the noble Lord, Lord Winston, does he think we should leave open the possibility of gene-editing great apes?

[Baroness Bennett of Manor Castle (GP)]

My Lords, I have the greatest respect for the noble Lord, Lord Cameron of Dillington, but I think the contribution that the noble Lord has just made demonstrates a fundamental difference in approach to, understanding of and belief in systems for—to use the phrase—feeding the world between him and several of us on this side of the House. I am going to take a very practical example of this because, last week, we saw reports emerge in the mainstream media of a new wheat variety called Jabal. The noble Lord spoke about our scientists finding solutions for Africa, and he spoke about leaving it to business. He said that only big companies could now develop new varieties of crops such as wheat. Jabal, which means mountain in Arabic, is a new durum wheat which is extremely tolerant to drought and heat. It was developed for climate resilience through the Crop Trust’s Wild Relatives project. It was developed between 2017 and 2021, so over a period of five years, and by working with farmers on the ground in the communities affected. It is looking to be extremely successful. There is no big business. There are some scientists—I have no doubt that there were some British scientists, but scientists from all round the world were involved in this—but it is grounded in the communities that need these crops and has been done without anyone making huge amounts of money out of it. If we are talking about feeding the world, there is a potential alternative model.

However, I am now going to come back to the detail of these amendments, starting with Amendment 16, already very ably introduced by the noble Baroness, Lady Bakewell of Hardington Mandeville. I do not really think that I need to add much to that, having attached my name to amendment, although I will note that Amendments 76 and 77, both of which appear in my name and which the noble Baroness has also kindly signed, have more or less the same intention of inserting in Clause 43 instead of earlier in the Bill. Amendment 77 looks at impacts on UK exports to the EU, as the earlier amendment did. Amendment 76 is broader and looks at exports around the world and what impacts it might have.

Amendment 78 in my name, which the noble Baronesses, Lady Bakewell and Lady Hayman, have kindly signed, addresses some of the points raised by the noble Lord, Lord Cameron. It says that regulations under this Act must particularly look at the impact on small and medium enterprises. Here, perhaps we are not thinking so much about enterprises that might be producing those so-called precision-bred organisms, but more the farmers using them and small farmers and the kind of impact we were addressing on the debate about intellectual property and the issues of market dynamics and competition which have been such an area of concern with GMOs.

Finally, I come to Amendment 75 in my name; the noble Baroness, Lady Hayman, also kindly signed it. If the noble Baroness, Lady Noakes, were here, she would probably be giving me lessons in the structure of Bills and exactly how a five-year review should be constructed. In her absence, I have done my best to propose that there should be a five-year review of how the Bill is working.

The debate on animals and plants provided some powerful ammunition for the discussion. The Minister acknowledged that the Bill will evolve and change according to events, but we also need to note that this is a fast-moving area of both technology and scientific understanding.

I will not go into great depth on what has been roughly described as the new biology but huge, fundamental debates within the science of biology are going on at the moment about the structure of organisms, of life and of ecosystems. In five years, the scientific framework behind this—not just the technology but scientific understanding—may well have moved on significantly. Surely a Bill this controversial, complex, difficult and technical should have a five-year review built in.

[Lord Winston (Lab)]

I never thought I would be a member of the Green Party, but I clearly am this evening. I must agree with the noble Baroness, because we have to understand that gene editing is a new technique and has been on the books for only about eight or 10 years, which seems a long time but is not at all—in science, that is a very short time.

It was 40 years ago that we genetically modified organisms for the first time. The noble Lord is proposing that we speed this process up when we do not fully understand what is happening with procedures such as CRISPR-Cas9 and other methods. We need much more data before we can be sure about the progeny of these animals. That is one of the problems, and it will not be simple.

Of course, I appreciate that it takes quite a long time to breed an animal. As a human, I understand that quite well—I have dealt with a few humans myself, and no doubt the noble Lord, Lord Cameron, has also had children—but we have to accept that it takes time before you can really work out the status of an animal. It is a complex process.

--- Later in debate ---

[Baroness Bennett of Manor Castle (GP)]

My Lords, I shall speak briefly to Amendment 19, which noble Lords will see already has a full complement of signatures. I thought the signature of the noble Lord, Lord Krebs, was far more useful than mine, so I was pleased to leave that space. If the Minister cannot agree to make some commitment such as that which the noble Baroness, Lady Jones, of Whitchurch, just asked for, it might well be possible to find a Conservative Back-Bencher to make a complete set on Report, should we get to that stage. I would have attached my name to this and I think it has already very been powerfully argued for, but I want to make two additional points.

Both the Environment Act and the Agriculture Act were built around the idea of public money for public good. Here, surely the Conservative Government would embrace the idea of public good for no public money at all. This is the Government able to make the rules, and they can ensure that there is public good without a penny having to be spent. That would be very much in line with the Environment Act and the Agriculture Act.

I want to highlight a couple of the elements in Amendment 19 that I think are particularly important, including sub-paragraph (x),

“supporting or improving human health and well-being”.

I note that the Government, in promoting the Bill, talk a great deal about sugar beet. Given the massive overconsumption of sugar in the UK diet—if we produced by volume only two-thirds of the sugar we produce in the UK, that would be more than enough for a sufficient, healthy level of diet without importing a single gram of sugar—and the fact that sugar beet is associated with massive loss of fertile topsoil from some of the richest lands in the UK, if we could gene-edit sugar beet to be more productive on less land, it would be ideal to combine that with ensuring that we produce only a healthy amount of sugar and free up the land for other purposes.

I also note that the Minister talked about sub-paragraph (ii), mitigating and adapting to climate change—indeed, he talked about the climate emergency quite a lot this afternoon. Of course, when we are talking about animals, we talk about engineering cattle to release less methane; we are looking at a whole-systems approach here, and having fewer cattle would be by far the easiest way to produce less methane. Further, they would not be consuming grains and proteins, such as soya from the Amazon, which we could be consuming as human food instead. It is a complex issue, but what we are getting at here is trying to deliver, as the noble Lord, Lord Krebs, said, what the Minister said is the purpose of the Bill.

The noble Lord, Lord Winston, has not spoken yet, but I will venture to make one comment on his Amendment 21. The wording is not terribly clear, and the noble Lord could answer now or later, or think about this amendment on Report. It says that the genome should be sequenced and the changes recorded and reported to the Secretary of State. My question is whether that should be published and publicly available. We are talking about licensing something that the Government are giving companies the right and the chance to potentially make money out of, so it is perfectly reasonable to demand an increase in public knowledge to make accessible those genomes that would then be available to other researchers for all kinds of possibly very different purposes, not necessarily productivity or seed-producing purposes. The knowledge of all those genome sequences would be a very useful thing. I think that should perhaps be written into the amendment.

[Lord Winston (Lab)]

Seeing as my name has been mentioned, perhaps I ought to speak. I thought we were still on the two previous amendments. The difficulty I have with this is that Amendment 21 is really a continuation of Amendment 20, and Amendments 22 and 23 follow logically.

Let me just deal very quickly with this. Basically, what we are talking about here is the release of organisms into the environment, and the proof that we have done to those organisms what we what we said we were going to do. Of course, that particularly means looking at the phenotype of the animal, whether it is a normal animal and therefore not suffering in any kind of way, and at whether the editing has changed the genome in a way that is unexpected. Of course, the Minister mentioned off-target mutations, but that is only one thing that can occur with gene editing. Once the DNA is on a double-stranded split and there is a gap there, you can actually introduce foreign DNA—even human DNA; whatever is floating around in the laboratory. When we are doing very careful work in the lab with genetic material, we have to be scrupulously clean of the flow hoods and so on. Those things need to be considered, because they would be part of what is seemingly a simple procedure, but in reality there are really quite difficult safeguards. What I am really asking is whether the Government intend that there be some form of sequencing to see whether there have been mistakes, or some form of examining the genome of the animals after we have done the work required.

To my mind, there are two issues here. One, of course, is the need to get better data on the effect of the gene editing, wherever it is done, and, in particular, of gene editing in general. That will help the research. If we really want to promote a market, we need to show that we are what we promised to be: a leading scientific organisation in this country, doing this sort of stuff at the top level. That is important. The other issue, of course, is protecting the environment. Clearly, release of organisms that turn out to be not what we expect, and which would have the ability to produce progeny, is risking things further. That is basically the reason for all these amendments, but Amendment 21 expresses my main concern: to ensure that we have done what we promised to do, and if we have not, to find what went wrong so that we can deal with it.

The primary question of privacy of the information has to be discussed by us, but it is deliberately not in this amendment at the moment. There are pros and cons for doing that. There does not necessarily have to be openness, but there must be a proper register of the information. We may well not get the work done if we do not have complete confidentiality, although science is never done best when it is confidential. On the whole, openness has been described, in the general information about the Bill, to be an issue in it, and transparency is a word mentioned by the Government. In the interest of transparency, this amendment may be required.
