Sao Paulo: Brazilian right-wing Senator Flavio Bolsonaro has followed his imprisoned father's lead by refusing to concede defeat to leftist President Luiz Inacio Lula da Silva, who won a historic fourth term in Sunday's presidential election.
Bolsonaro, the son of former President Jair Bolsonaro, called into question a late-Sunday decision by a Lula-appointed Supreme Court justice that extended voting by two hours over alleged voter transport irregularities. He said he would ask for the result to be annulled.
