Lungu received 48.3 per cent of the vote, while Hakainde Hichilema of the United Party for National Development came in second with 46.7 per cent after votes were tallied from all 150 constituencies in the southern African nation, said acting Chief Justice Lombe Chibesakunda late yesterday.
Lungu, who heads Zambia's justice and defense ministries, will serve out the remainder of Sata's term until elections next year. Sata died after a long illness.
"The election was stolen and does not reflect the will of the people," he said.
Zambia's electoral commission chairwoman Ireen Mambilima has dismissed the allegations, saying the process was transparent.
Zambians voted on Jan. 20, and the polls were extended by an extra day, due to heavy rain in certain areas.
During the election campaign, Lungu, who belongs to the same party as the late president, said he wants to complete economic development projects initiated by Sata.
