Brazil's ex-President Luiz Inácio Lula da Silva has been cleared of corruption by a Supreme Court judge, opening a path to a possible run for the presidency in 2022. Lula, a leftwing icon to many, was freed in 2019 after 18 months in jail. He was convicted following an investigation, Operation Car Wash, into a huge bribery scandal which ensnared politicians and business leaders. But Supreme Court Justice Edson Fachin annulled Lula's convictions. He said in a statement that a court in the southern city of Curitiba did not have the right to try the four cases, which should instead be heard by a federal court in the capital, Brasilia. The ruling, which still has to be considered by the full Supreme Court, restores Lula's political rights, unless he is convicted again. Lula, president from 2003 to 2010, could theoretically run against President Jair Bolsonaro. The right-wing incumbent is thought likely to seek re-election next year. Lula, now 75, was jailed in 2018 for 12 years for receiving a beachside apartment from an engineering company implicated in the Operation Car Wash investigation. This was later reduced to eight years and 10 months. In 2019, he was given a further 12 years in jail for accepting bribes in the form of renovation work at a country house from construction companies. But in the same year, he was freed after the Supreme Court ruled that defendants should not be jailed until their appeal process has been exhausted. Lula had denied all the charges, saying they were aimed at preventing him from running for president again in 2018. The Operation Car Wash investigation began in March 2014. It centred on allegations that executives at the state oil company Petrobras had accepted bribes from construction firms in return for awarding them contracts at inflated prices. Lula's Workers' Party was engulfed in the scandal following allegations it took some of these funds to pay off politicians and buy their votes and to help with political campaigns.
