Gene Editing

Jim Shannon Excerpts

Tuesday 22nd July 2025 Westminster Hall

[Steve Barclay (North East Cambridgeshire) (Con)]

I beg to move,

That this House has considered the future of gene editing.

It is a pleasure to serve under your chairmanship, Ms Vaz. I secured this debate as gene editing provides immense opportunities to the United Kingdom in boosting growth in our agricultural sector, in supporting our world-leading life science industry and in better protecting our environment for future generations. Being able to diverge from the European Union on the regulation of gene editing is a genuine Brexit opportunity, but there is much concern that the Labour Government’s EU reset will pause or even reverse the progress made in the UK in setting out a new path to regulate that exciting technology and, in doing so, will sacrifice a key opportunity to help our farming community.

Almost all our domestic animals and plants are the result of thousands of years of selective breeding. Gene editing is best thought of as a modern enhancement of that technique. It is often referred to as precision breeding. It allows scientists to make changes to a plant or animal’s DNA, cutting the DNA strand and then adding, deleting or altering sequences to give beneficial traits, which make for things like disease and drought-resistant crops, or indeed more nutritious crops.

[Jim Shannon (Strangford) (DUP)]

I commend the right hon. Gentleman for securing the debate. This is an incredibly important issue to the farming community that I represent and those across the United Kingdom of Great Britain and Northern Ireland. He is presenting some incredibly interesting facts. Does he agree, however, that we must be careful in any consideration of the future of gene editing to maintain a boundary between gene therapy and gene enhancement? We must ensure that we are not generating superhuman traits, as opposed to seeking to cure genetic traits, which is something we can all agree on. The key issue, as he says, is the issue of drought and disease-resistant crops, which are critical to the farming community.

[Steve Barclay]

The hon. Gentleman is a champion of the farming community. He and I, in my previous role, often discussed farming issues, and we both hugely support the importance of food production as a key part of our food security. He is right to draw attention to the fact—I will come to this—that gene editing and gene modification are often confused, when they are very distinct. The crucial point to share with the House is that the changes in gene editing are limited to those that occur naturally or through conventional selective breeding. That is the distinction I will come on to with gene modification. By using gene editing, we can get to a desired trait more quickly. Science therefore accelerates something that could happen naturally, as opposed to being an artificial intervention.

Let me give an example of how gene editing can provide a win-win in practice in our farming community. I represent North East Cambridgeshire, which is the centre of UK sugar beet production. That crop has been severely impacted by virus yellows disease. At the moment, the only way to tackle it is by using a seed treatment, Cruiser SB, which is toxic to pollinators such as bees. Given the downsides for nature, the treatment needs to be granted emergency authorisation on a year-by-year basis. The last time that the authorisation was not made available was in 2020, and 25% of the national sugar beet crop was lost. Without authorisation of something that is accepted as damaging to nature, the crop fell by a quarter, which is a severe consequence.

That led to an economic loss of about £67 million, in an industry involving 10,000 jobs. After some years of approval the current Government have decided that authorisation will again not be available in 2025, which has left the sector with a lot of uncertainty. But instead of requiring us to choose between nature and crop yields, gene editing provides a better solution. Under the previous Conservative Government, a £660,000 grant was made jointly to British Sugar, the agricultural biotechnology company Tropic, and the world-leading plant science institute, the John Innes Centre, to fund gene editing research into sugar beet resistance to virus yellows disease.
