The Natural History Museum has raised questions over its judgement after accepting sponsorship for a photographic exhibition from a company voted by corporate watchdog The Public Eye as having “the most contempt for the environment and human rights” in the world.

The company, Brazilian mining giant Vale, in involved in the building of the Amazon Belo Monte dam, which critics say will destroy some of the environments and the lives of indigenous people living there, both captured in the Genesis photo exhibition at the museum this summer.
