Zambia's President Edgar Lungu has defeated his main rival Hakainde Hichilema in the country's presidential election. Zambia's electoral commission says Lungu, leader of the Patriotic Front, won 50.35 percent of the vote against 47.67 per cent for Hichilema of the United Party for National Development. The opposition party has already cried foul. It says it will petition the country's Constitutional Court to relook at the whole electoral process, claiming that fraud took place. This might delay the inauguration of the president for a second term.
