 A Brazilian mayor, part of a 200,000-strong group claim against miner BHP over a 2015 burst dam, has told an English court that suing the Anglo-Australian giant in Brazil would be like David fighting Goliath - without the biblical ending. Mario Antonio Coelho, mayor of Brazils Barra Longa municipality, has told a jurisdictional hearing in Manchester that bringing the 5 billion pound 6.3 billion case in England over Brazils worst environmental disaster is the only route to proper justice, court documents show. Duarte Junior, the mayor of Mariana, who has travelled to Manchester, northern England, with Rio Doces mayor Silverio da Luz, urged BHP to listen to Brazilians.
