Robert Mugabe may have disappeared from the public view, but his ghost still lingers over a vote which threatens to be one of the closest in the country's history.
Mugabe, now 94, ruled Zimbabwe for 37 years before resigning last November
amid the pressure of a military takeover and the humiliation of impeachment.
Emmerson Mnangagwa, the man who Mugabe fired as his deputy only weeks before his resignation while attempting to have his wife appointed as his successor, now leads the country and the Zanu-PF party.
Mugabe has rarely been seen in public since, instead spending his time between Singapore, where he is receiving medical treatment, and his plush 25-room Blue House residence in the nation's capital Harare.
Sightings of Mugabe's wife Grace, nicknamed "Gucci Grace" for her love of a lavish lifestyle, have become similarly scarce.
But on Sunday, Mugabe made a rare public appearance to declare he would not vote for his successor Mnangagwa.
"I can't vote for Zanu-PF. I can't vote for the people who have brought me into this state," Mugabe said during a news conference at his mansion in Harare, on the eve of the election.
"I must say clearly I cannot vote for those who have tormented me. I can't. I will make my case among the other 22 [out of the 23 candidates]."
The former leader added it was "painful" that his name would not be on the voting ballot but that it was "the reality."
Before Sunday "Mugabe himself has not been visible, he's not been saying much about this election," Dewa Mavhinga,
Southern Africa Director of Human Rights Watch told CNN.
"There are people who remain loyal to him within Zanu-PF, so that would be a factor -- and that factor might actually reduce the levels of support that the presidential candidate for Zanu-PF enjoys."
That candidate is the current president, Mnangagwa, who has attempted to rebrand the ruling Zanu-PF party. He has already survived one attempt on his life ahead of this election when a grenade was thrown at the stage during a campaign rally last month.
The 75-year-old is still widely considered as Mugabe's man given that he worked so closely with him for more than 40 years, first as his special assistant during the 1977 liberation war, and later as security minister and justice minister.
