BRASILIA, Oct 25 (Reuters) - Brazilian Senator Flavio Bolsonaro said on Sunday he would not concede defeat to President Luiz Inacio Lula da Silva, who secured a fourth non-consecutive term, and would seek the annulment of the runoff election.
Bolsonaro said a ruling by Supreme Court Justice Cristiano Zanin extending voting for two hours was "unacceptable".
