Environment Secretary Owen Paterson will reopen the controversy over genetically modified crops with a speech extolling the benefits of the technology.
Mr Paterson will say that government, scientists and industry "owe a duty to the British public to reassure them that GM is a safe, proven and beneficial innovation" for farmers and consumers.
He will claim that there are potentially significant economic and environmental benefits to growing GM produce, including increasing yields, protecting crops from disease and reducing the use of pesticides and chemicals.
