Brazilian President Luiz Inácio Lula da Silva has won a fourth, non-consecutive term after defeating right-wing challenger Flávio Bolsonaro in the presidential runoff. Lula secured around 51.8% of the votes, while Bolsonaro received 48.2%, according to the reported results. The victory marks a major political comeback for the 80-year-old leader and reflects Brazil’s deep political divisions.

Flávio Bolsonaro, son of former president Jair Bolsonaro, challenged the result and called for the election to be annulled. Lula’s victory is expected to shape Brazil’s domestic policies, international relations and role in Latin American politics.
