SAO PAULO (Reuters) - Millionaire businessman Joao Doria of the centrist Brazilian Social Democrat Party has won the race for mayor of Sao Paulo, Brazil's largest city, in local elections on Sunday that were a major setback for the leftist Workers Party.


With 9.9 percent of votes left to count, Doria had won over 53 percent, enough to avoid a runoff, according to official results.


Based on the percentage of blank and nullified votes, along with voters who did not turn out, Reuters projects that Doria has won. His victory bolsters a likely presidential bid by the PSDB governor of Sao Paulo, Geraldo Alckmin, in 2018.
