An artist who has made his name by sending giant rubber ducks around the world has accused Brazilian protestors of plagiarism, after they used a similarly enormous rubber bird as a statement against their president.
Brazilian industrial group, FIESP, commissioned the duck to use in protests against corruption and high taxes. The duck bears the slogan "Chega de pagar o pato" across its chest, a Portuguese saying that translates to "We won't pay for the duck any more" or "We won't pay for what is not our fault any more".
However, Dutch artist Florentijn Hofman, who has created his waterfowl sculptures in cities including Hong Kong and put other animals, such as an enormous hippo, in rivers including the Thames, claims that the more politically charged animal is a direct replica.
Hofman told The BBC: "It is exactly our design and our specific technical patterns. Changing the eyes doesn't change our technical design of the shape and beak."
The Brazilian duck has crosses for eyes as well as the slogan across its front, and was made by the same Sao Paolo giant duck factory that created Hofman's birds. The factory denied any wrongdoing, but claimed they had spent "four hours redesigning" the duck.
"I would not put our reputation at risk," he told the BBC. "We have experience in this kind of job and this is a very simple design. Why wouldn't we spend four hours redesigning it?"
However, Hofman said the factory "made a very unwise decision" and that he considered it "illegal use of the exact design and therefore copyright infringement".
The FIESP maintain that they were told their duck was an original. Along with the controversial giant duck, the group has also staged protests with thousands of smaller rubber ducks in the country's capital, Brasilia, to help oust Rousseff over claims she altered government accounts to hide a growing deficit.
