A Federal Court in Brazil has ordered the trial of former President Luiz Inacio Lula da Silva, for obstruction of justice.
The trial was pronounced in a ruling on a case linked to the scandal at the state oil company Petrobras.
Lula, who was President from 2003 to 2011, was accused of hindering Operation Car Wash, the inquiry into the multi-billion-dollar company.
He has denied committing any offence.
Mr Lula was earlier detained and brought in for questioning in March, when Federal Police agents stormed his residence.
