Lusaka - Following his success in the August 11 polls, newly re-elected Zambian President Edgar Lungu has told opposition parties to not be bitter over his victory, Lusaka Times reports.While addressing supporters during a thanksgiving rally on Tuesday, Lungu told his rivals that this was not the time for bitterness, but instead a time for the Zambian nation to unite in order for development and progress to take effect."When there's extreme bitterness and extreme happiness you create a poison. I want us to continue living under the doctrine of One Zambia One Nation, regardless of how we voted in the last election. I want to reach out to the people in Western Province, North Western and Southern Province, find out why they did not vote for us so that we can do better in next polls," Lungu was quoted as saying.He also requested that all citizens remain calm and await his inauguration, which could be delayed due to a court order filed by the opposition.According to opposition leader Hakainde Hichilema, certain factors within the recent polls were rigged. Hichilema described the results as a coup against the southern African country’s democratic processes.Hichilema accused the country's electoral body, the Zambia Electoral Commission (ECZ), of manipulating the results in favour of Lungu’s Patriotic Front, following which he approached the court.Both the Electoral Commission and the ruling Patriotic Front have since rejected Hichilema's claims, stating that the opposition leader was making inflammatory statements in a bid to rid himself of frustrations.As a result of the court action, Lungu may only be sworn in two weeks from the time at which the court action is instituted.
