Mugabe sacked Mujuru on Tuesday and was expected to name a new cabinet, some government sources said.
The sources said Mujuru had received her dismissal letter on Monday night after weeks of accusations that she had led a “treacherous cabal” to try to unseat Mugabe.
Mujuru on Tuesday blamed “a well-orchestrated smear campaign and gross abuse of state apparatus” that led to the loss of her ruling party post.
The Vice President, who once looked likely to succeed long-ruling Mugabe, has been accused of plotting to assassinate the 90-year-old and was removed from the ruling ZANU-PF party’s central committee.
She said she was being victimised after exposing infiltrators conspiring to destroy the party which has ruled the country since independence in 1980.
“I have become the fly in the web of lies whose final objective is the destruction of ZANU-PF and what it stands for and ultimately the present government,” Mujuru said in a statement.
“A vociferous attempt has been made to portray me as ‘a traitor’, ‘murderer’ and ‘sellout’, yet no iota of evidence has been produced to give credence to the allegations,” she said.
ZANU-PF held an elective congress last week which endorsed Mugabe as president and his wife Grace as head of the women’s wing.
