Lusaka - Zambia will hold a presidential election on Tuesday to replace Michael Sata, who died in October after a long illness.
Eleven candidates are vying for the top post in the southern African nation. Zambia has been led since Sata's death by acting president Guy Scott, a white Zambian of Scottish descent who is not a candidate.
The main presidential contenders are Edgar Lungu of the ruling Patriotic Front party and Hakainde Hichilema, leader of the opposition United Party for National Development.
