Mnangagwa had clashed repeatedly with First Lady Grace Mugabe, 52, who was widely seen as vying with him to succeed her 93-year-old husband as president.
Following General Constantine Chiwenga's decision to challenge Mugabe's mistreatment of former Vice President Emmerson Mnangagwa, Zanu PF has fired back at the army stating that the military boss is guilty of mishandling $15billion in diamond revenues.
Mugabe has threatened to fire more than 100 officials linked to Emmerson Mnangagwa, the vice president he sacked last week and who enjoys the support of the influential War Veterans' Association.
The party said his comments were "clearly calculated to disturb national peace..."
Although the ruling ZANU-PF party has said it would never succumb to military pressure. Whilst reports on social media seem to imply that a coup is underway, Khuluma Afrika understands that military presence has been increased there to improve security in the face of growing uncertainty in the country.
Several tanks have been seen heading towards the capital of Zimbabwe, less than a day after the head of the military said he could "step in" to end President Mugabe's "purge" of opponents.
"We must remind those behind the current treacherous shenanigans that, when it comes to matters of protecting our revolution, the military will not hesitate to step in".
Speculation has been rife in Harare that Mugabe could seek to remove Chiwenga, who is seen as an ally of ousted Mnangagwa.
"As a result of squabbling within the ranks of Zanu-PF, there has been no meaningful development in the country for the past five years".
"We will not fold out hands to allow a creature of the constitution to subvert the very constitution which establishes it", said Kudzai Chipanga, who leads the Zanu-PF Youth League, said at the party's headquarters in Harare.
Chiwenga said if this happens, the military will interject and stop the process.
Mnangagwa took over as vice president from Joice Mujuru who was axed in 2014 after Grace Mugabe launched a campaign accusing her of plotting to topple the president.
"The current purging ... targeting members of the party with a liberation background must stop forthwith", he said.
Grace, now poised to become a vice president, did not fight in the liberation war.
