In last month's Campden BRI lecture, Warburton called on the Food Standards Agency (FSA) to "battle on" in its call for an open GM debate following adverse publicity from two high-profile resignations from the FSA's GM dialogue steering group.
"Modern technology offers some potential to improve the quality and quantity of food available," said Warburton. "By 2030 we will have to have formed a clearer view about the environmental, safety and consumer benefits of GM. I worry if we haven't."
Professor Brian Wynne, a sociologist at Lancaster University, and GeneWatch UK director Helen Wallace resigned after just two meetings of the steering group, accusing it of pro-GM bias. This was strongly refuted by FSA chairman Lord Rooker.
