SAO PAULO, Aug 26 (Reuters) - Brazil's benchmark Bovespa stock index topped the 60,000-point threshold for the first time in over a year and a half on Tuesday, driven by speculation that upcoming poll data will show declining support for President Dilma Rousseff ahead of October elections.
Investors have been critical of Rousseff's administration for heavy government meddling in the private sector and have accused her of mismanaging state-run enterprises such as oil producer Petroleo Brasileiro SA, known as Petrobras.
At 10:35 a.m. local time (1335 GMT), the Bovespa was up 0.18 percent to 59,839.92 shortly after touching an intraday high of 60,020.01 points. (Reporting by Asher Levine; Editing by Jeffrey Benkoe)
