Gene Editing

Debate between Josh Newbury and Steve Barclay

Tuesday 22nd July 2025 Westminster Hall

[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.

The right hon. Gentleman is making an important point about the potential for gene editing or precision breeding. Does he agree that one of the clearest examples of its promise is the humble potato? During a recent visit that the Environment, Food and Rural Affairs Committee made to the John Innes Centre, which he mentioned, we met Tropic and saw at first hand how researchers are using precision breeding to develop a blight-resistant potato, a breakthrough that could dramatically reduce the need for fungicide use. It could cut costs for farmers and improve yield resilience in the face of climate change. Does he agree that public engagement and clear, science-led regulation will be key to ensuring that those advancements deliver for both farmers and consumers?

[Steve Barclay]

I very much agree. I will come on to public sentiment towards gene editing, which is extremely favourable, but it is helpful to have cross-party support because this is a win-win, as I have said. It boosts yields, helps farmers and reduces the cost of pesticide. It is also a huge benefit to nature. The hon. Member is right to praise the John Innes Institute, which is world leading. That is another reason why we should seize the opportunity that science offers.
