Edgar Lungu wins Zambia presidential election

Zambia's President Edgar Lungu has been re-elected, according to official results, which are being challenged by the main opposition party.
•    The electoral commission said Mr Lungu had secured 50.35% in Thursday's vote, just over the 50% threshold needed to avoid a second round under a new electoral system.
•    His main rival, Hakainde Hichilema, who alleges electoral fraud, won 47.67%.
•    Mr Hichilema described this election as a sham which did not reflect the will of the people.
•    He plans to petition the constitutional court to challenge the result. 
•    He may well be going at it alone because of the fluidity of Zambia's political landscape.
•    Mr Lungu defeated Mr Hichilema in the previous election, last year, by less than 28,000 votes. This time, his margin of victory was about 200,000 votes.
