Ecuadorean leftist Lenin Moreno won Sunday's presidential election after a tight contest with his right-wing opponent. The country's electoral council said this today. <br/>'<br/>According to the council, Moreno pocketed 51.16 per cent of valid votes versus 48.84 per cent for conservative challenger Guillermo Lasso, with 99.65 per cent of votes counted. <br/><br/>The results are "irreversible," electoral council president Juan Pablo Pozo said, adding there was no indication of fraud. <br/><br/>"Ecuador has chosen freely," he said in a televised speech. Still, Lasso has said he will challenge the results. <br/>'<br/>The Organization of American States, which had an observer mission in Ecuador, said yesterday it had seen "no discrepancies" between results collected by its observers at polling stations and official results.<br/>
