Demonstrators dressed as chickens, a cow and President Donald Trump gathered Saturday in London to protest a proposed U.S.-U.K. trade deal that activists say will lower food safety standards.

One protester wore an oversized Trump head and carried a giant syringe to highlight concerns that beef treated with hormones could be sold in the U.K. Critics are also worried about the importation of chickens washed in chlorine, a practice they suggest covers up poor animal husbandry practices.
