Challenger 'wins Zambia presidency'
Challenger Michael Sata has defeated the incumbent in Zambia's presidential elections, the chairwoman of its Electoral Commission has said.
Irene Mambilima announced that with counts completed from nearly all the country's 150 constituencies, Mr Sata had won with 1,150,045 votes, or 43% of the total.
President Rupiah Banda had 961,796 votes, or 36.1%. Eight other candidates shared the remainder.
Mr Banda's party, of which Mr Sata had been a member until a 2001 leadership dispute, had been in power for two decades.
