Grace Mugabe’s promotion to head of Zanu-PF’s women’s wing puts her in a good position to succeed her husband in the future, analysts say.
The first lady has criticized political rivals, including Vice-President Joyce Mujuru, in recent months.
Mugabe, 90, is due to stand for election again in 2018.
Speaking at Zanu-PF’s congress, Mugabe thanked thousands of supporters for choosing him as party leader.
“I know where I come from… I am not greater than the people who gave birth to me,” Mugabe, who has led Zimbabwe since 1980, said.
The first lady’s appointment as head of the women’s wing is seen as a further sign that Mujuru, who was once seen as a potential successor to Mugabe, has been sidelined.
Mujuru fought alongside Mugabe for Zimbabwe’s independence from white-minority rule.
However, her career ran into trouble when Mrs. Mugabe, 49, entered politics this year, and accused the deputy of plotting against her husband.
Speaking to the congress on Thursday, Mr. Mugabe described Mrs. Mujuru as a corrupt thief, and said she had planned to assassinate him.
He said he welcomed the fact that his wife had exposed Mrs. Mujuru’s attempt to oust him.
However, recently expelled Zanu-PF member Rugare Gumbo told the BBC that Mugabe had targeted Mujuru to advance the “fortunes” of his wife.
The congress also gave Mugabe the power to appoint his deputies—increasing his control over the party.
Mugabe told supporters that he would announce a successor to Mujuru later this week, AP news agency reported.
With Mujuru’s fall from grace, there is speculation that Justice Minister Emmerson Mnangagwa will be given a top position.
