Lula ahead in polls for Brazil's first-round vote; runoff likely

​A series of polls ‌on Saturday showed ​Brazilian President Luiz Inacio Lula da Silva slightly ahead of Senator Flavio Bolsonaro ‌before Sunday's first-round vote, and a close race in a likely runoff between the leftist incumbent and his right-wing challenger.

If no candidate wins ‌more than 50% of valid votes -- which exclude blank and ‌null ballots -- on Sunday, the two frontrunners advance to a second-round runoff on October 25. CNT/MDA POLL
