Mugabe missed the deadline given to him by the ruling Zanu-PF party of noon on Monday (10am GMT) to resign or be impeached. Just a day earlier, the 93-year-old read a long speech on state TV about the need for the country to "return to normalcy". He was fired as party leader and replaced with former vice president Emmerson Mnangagwa, whose sacking by Mugabe sparked the current crisis, but Mugabe has so far refused to stand down as president.
According to Reuters, Zambia has sent former president Kenneth Kaunda to Harare to try and persuade Mugabe to step down in a "dignified exit". Meanwhile, Zanu-PF has called all of its MPs and senators to a meeting at its headquarters to discuss Mugabe's impeachment, just two hours after his missed deadline.
On Sunday, Mugabe's son Chatunga Bellarmine Mugabe showed his steadfast support for his father in a Facebook post. Using his father's clan name of Gushungo, he wrote: "You can't fire a Revolutionary leader ! Zanu Pf is nothing without President Mugabe. Gushungo will always remain the champion of champions! Proud of you Gushungo Proud of Dad. Gushungo always and forever to death."
But not everyone used social media in such a sincere way, with many creating memes to mock Mugabe's clinging onto power.
