Protestors are set to gather outside the Perrier Comedy Awards ceremony tonight to protest at what they say is parent company Nestle's unethical standards.

Campaigners say the gathering, outside Edinburgh Art College, will be light-hearted.
They accuse Nestle of aggressively promoting powdered milk in third world countries ahead of breast feeding.
