A new public opinion poll shows Brazil's president widening his lead in the run-off election for another term.

Polling data released Wednesday shows 60 percent of respondents support President Luiz Inacio Lula da Silva - up four percent from a poll last week. Support for his opponent, former Sao Paulo Governor Geraldo Alckmin, slipped four percentage points, to 40 percent.

The results were based on interviews with more than 7,000 voters conducted by a Brazilian polling firm, Datafolha. The margin of error was plus or minus two percentage points.

President da Silva failed to win an outright victory in the first round of voting October first, capturing 48.6 percent of the vote. Mr. Alckmin, the Social Democracy Party's candidate, won 41.6 percent of the vote.

The run-off election is scheduled for October 29.
