A group of Brazilian anthropologists and environmentalists has put forward Chief Raoni Metuktire of the Kayapo tribe as a candidate for the 2020 Nobel Peace Prize for a lifetime of work protecting the Amazon rainforest.

Raoni — an unmistakable Amazon icon with his large lip plate, yellow macaw-feather headdress and earrings — became known internationally as an environmental campaigner in the 1980s with musician Sting at his side.

At 89, Raoni took to the road again this year seeking help to stop a surge in fires destroying the forest, which he has blamed on plans by right-wing President Jair Bolsonaro to develop the Amazon economically and assimilate its indigenous people.
