UK Prime Minister Tony Blair has responded to a letter sent to him on behalf of 114 scientists, criticising his handling of the debate over genetically modified organisms (GMOs), saying that the government would make its decision on the basis of 'sound science'. Mr Blair said that he read the letter with interest, and added that: 'The reason why we have not yet made a formal response to the results of the farm scale evaluations is that we are waiting to hear the assessment of the advisory committee on releases to the environment.' Mr Blair made it clear, however, that consumer concerns are not the only arguments that will influence the government's decision. 'I strongly believe that science and technology are vital to our country's future prosperity. As a government, we need to ensure that the UK continues to be one of the top countries in the world for scientific research,' he said.
