Malawi's President Peter Mutharika on Saturday said the re-run of the country's general election this week was marred by "irregularities", as unofficial tallies showed him losing to the opposition leader. "We expected an election without irregularities," Mutharika told reporters in the second city of Blantyre. "Sadly, as all Malawians have seen, this election is the worst in Malawi's history of our elections." str-sch/dl
