Polling stations opened Sunday in Peru in a tight presidential runoff election that pits two populists against each other, as dpa reported. Final opinion polls prior to the election showed a technical tie between left-wing nationalist Ollanta Humala and right-wing Keiko Fujimori. Polling stations opened at 8 am (1300 GMT) and were to close eight hours later. Electoral authorities have said the first results would be available around 8 pm (0100 GMT Monday).
