Baby Milk Action, which co-ordinates the international boycott of Nestle products, cheekily collected an award on behalf of the giant multinational on Sunday.
Nestle was named the least ethical company operating in the UK by readers of Ethical Consumer magazine and opted not to collect the award. The boycott is over Nestle's sale of powdered milk in the Third World.
The award was picked up by Mike Brady, the group's campaigns and networking co-ordinator.
"The award acknowledges the success of campaigners in exposing corporate malpractice and the shocking failure of Nestle to abide by minimum standards in a whole host of areas," he said. "The boycott is succeeding in saving infant lives by bringing about grudging changes from Nestle."
The awards, which also named Esso petrol as least ethical product and Green & Black's chocolate as best ethical product, concluded the first Ethical Consumer World Exhibition in London.
