Lula wins unprecedented fourth term as Brazil's president

Brazil's left-wing President Luiz Inacio Lula da Silva won an unprecedented fourth term in Sunday's election, defeating conservative rival Flavio Bolsonaro, who has announced plans to challenge the result. Lula secured 51.8% of the vote against Bolsonaro's 48.2%, a margin of 4.4 million votes, despite trailing after the first round. The 81-year-old's victory marks the first time a candidate has overturned a first-round deficit since Brazil's return to democracy. Bolsonaro, son of convicted former president Jair Bolsonaro, alleged electoral fraud and refused to recognize the result. Lula's fourth term faces constraints from conservative legislative gains, and he has promised to regulate social media after accusing Meta of bias.
