Zimbabwe President Robert Mugabe agreed to resign on Sunday but his ruling ZANU-PF party did not want him to quit in front of the military, an act that would have made its intervention look like a coup, two senior political sources said on Monday.
"It would have looked extremely bad if he had resigned in front of those generals. It would have created a huge amount of mess," one senior source within ZANU-PF said.
Another political source said the speech was meant to "sanitise" the military's action.
Mugabe's resignation letter has been drafted
Mugabe has agreed to stand down after 37 years in power, CNN reported on Monday, after he avoided any mention of resignation in a rambling national address on Sunday night.
A resignation letter has now been drafted, CNN said, citing sources familiar with his negotiations with the generals who seized power in Harare last week.
Under the terms of the deal, Mugabe and his wife Grace would be granted full immunity, CNN said.
