The former president of Brazil, Luiz Inácio Lula da Silva, was found guilty of corruption and money laundering on Wednesday and sentenced to nearly 10 years in prison, a stunning setback for a politician who has wielded enormous influence across Latin America for decades.
The case against Mr. da Silva stemmed from charges that he and his wife illegally received about $1.1 million in improvements and expenses for a beachfront apartment from a construction company.
In return, prosecutors said, the company was able to obtain lucrative contracts from Petrobras, the state-controlled oil giant.
Plagued by scandals, Mr. da Silva’s leftist Workers’ Party lost the presidency last year when the Senate impeached his handpicked successor, Dilma Rousseff, in a power struggle that consumed the nation.
Mr. da Silva can appeal the conviction, but the ruling could deliver a serious blow to his plans for a political comeback. He had been considered a leading contender in next year’s presidential election.
