In Brazil, Senator Flavio Bolsonaro's legal challenge against President Luiz Inacio Lula's runoff victory will fuel right-wing protests, but it is highly unlikely to overturn the election result, leaving Lula to navigate a right-leaning Congress, fiscal pressures, tense relations with the United States and a succession debate in his fourth and final term as the country's leader. Brazilian President Luiz Inacio Lula da Silva was re-elected for a fourth non-consecutive term on Oct. 25 after receiving 51.8% of the valid vote in the presidential runoff election and defeating far-right Senator Flavio Bolsonaro, the eldest son of former President Jair Bolsonaro. The result represents an unprecedented comeback since Brazil's return to democracy in the 1980s, as no candidate who has ever lost the first round of a presidential vote has won the second.
