Aberdeen-based biochemist Dr Arpad Pusztai says the way he has been treated "stinks".

Dr Arpad Pusztai's research on the effect GM potatoes on rats' immune systems was discredited in a report by the Royal Society last month.

He had been suspended from his work at the Rowett Research Institute for going public with his concerns about the potential health risks of GM foods.

His government-funded project was stopped, and concerted efforts have since been made by scientists with government links to discredit his research.

Dr Pusztai has set up a Website to make his feelings known. In it, he wrote: "I think the whole thing stinks.

"I offered the Royal Society my full cooperation, but they decided I would have no other input than to provide them with the material."

He has published correspondence between himself and the Royal Society.

Dr Pusztai wants "transparency" on GM research

"This is a process which should have been done by the Royal Society, not by me," he said.

"My scientific colleagues deserve to see this. We live in an age when transparency ought to be a watchword."

Dr Pusztai, 68, a Hungarian-born nutritionist, said the Royal Society's criticisms were based on the design of his experiments, but it had not seen the research proposal which gave details of the design.

Dr Pusztai said he believed the Royal Society had acted entirely unfairly and hoped he could convince scientific colleagues that its criticisms were based on incomplete knowledge.

Last month's report by the Royal Society said that "no conclusions should be drawn" from Dr Pusztai's work, which was "flawed in many aspects of design, execution and analysis".
