The 75-year-old Mnangagwa fled Zimbabwe after Mugabe fired him earlier this month, leading the military to move in and kick off a series of extraordinary events ending in Mugabe stepping down yesterday amid impeachment proceedings.
Mnangagwa met with South African President Jacob Zuma in a jovial "courtesy call" before taking a private jet from Johannesburg to Zimbabwe's capital, Harare. He was said to arrive at ruling party headquarters, where he would be briefed by officials.
The privately run Newsday newspaper reported that Mnangagwa after his arrival was expected "to meet Mugabe for a briefing."
Several hundred people gathered in anticipation of his arrival. Some carried signs with images of him, suggesting a certain level of organization behind the jubilant turnout. Signs read "Welcome back, our hero" and "True to your word, you're back. Welcome."

Mnangagwa is a former justice and defense minister who served for decades as Mugabe's enforcer, a role that earned him the nickname "Crocodile."

"Never should the nation be held at ransom by one person ever again, whose desire is to die in office at whatever cost to the nation," Mnangagwa said.
