Fresh challenges in the great GM debate.
Pembrokeshire potato farmer Walter Simon, who supports GM crops, said: "For quite a while the public and politicians have been more interested in looking after the landscape and flowers than in food. I think that's changing now, because rising prices are symptoms of the fact that we've got a shortage of grains in the world. That changed the politicians' view of the world for food production."
Patrick Holden, director of the Soil Association, said there was a "danger" politicians would think GM food a good idea. "There are some significant politicians close to the lever of power who have a belief that GM could deliver a new era of greater food security. How would a politician who has never farmed, or been directly involved in agriculture, know better?"
