Groups opposing the use of GM crops in Africa and Asia are "wicked" and possibly condemning millions to an early death, Environment Secretary Owen Paterson told The Independent.
Friends of the Earth and Greenpeace, who are among those opposing GM technology, are "casting a dark shadow over attempts to feed the world", Mr Paterson claims.
The Environment Secretary also backed an open letter by international scientists calling for the rapid release of vitamin A-enhanced rice to help prevent the cause of around a third of the world's child deaths.
He told the newspaper: "It’s just disgusting that little children are allowed to go blind and die because of a hang-up by a small number of people about this technology.
“I feel really strongly about it. I think what they do is absolutely wicked.”
