There has been no official update on his condition and acting president Edgar Lungu had to lead celebrations last week to mark the landlocked nation's 50th anniversary of independence from Britain.
Waziri wa ulinzi Zambia Edgar Lungu amesema maandalizi ya uchaguzi huo yataanza muda wowote ambapo katiba ya nchi hiyo inaagiza kufanyika uchaguzi wa Rais ndani ya siku 90 baada ya kufariki kwa aliyekuwa rais wa nchi hiyo.
