Lusaka, Zambia - The results of Zambia's presidential by- election were trickling in Friday, showing opposition leader Michael Sata polling well in his strongholds in the capital Lusaka and the Copperbelt mining region.
Results from 16 constituencies in the Copperbelt showed him leading acting president Rupiah Banda by around two votes to one.
Sata had also taken two constituencies in Lusaka region, including Lusaka Central, while Banda had won two constituencies in his home region of Eastern Province.
With only around 20 of a total 150 constituencies announced, it was too early to call the election for either candidate. The final results could take several days.
