Brazilian senator Flávio Bolsonaro vowed late Sunday to seek the annulment of Brazil's presidential runoff, accusing Supreme Court justices of favouring President Luiz Inácio Lula da Silva after a last-minute extension of voting hours.
The Liberal Party candidate had led the first round on 4 October with 47% of the vote to Lula's 45%. Brazil's Superior Electoral Court subsequently declared Lula the runoff winner, with 51.79% of valid votes against Bolsonaro's 48.21%.
