Zimbabwe’s former Vice-President Emmerson Mnangagwa, who was sacked on Monday, has fled to South Africa amid death threats, his allies say.
President Robert Mugabe, 93, accuses his former deputy of plotting to take power from him.
“He went to apostolic church prophets to find out when Mugabe would die. But he was told he would die first,” Mr Mugabe told supporters on Wednesday.
First Lady Grace Mugabe is now the favourite to succeed her husband.
Mrs Mugabe had been pushing for the removal of the vice-president, referring to him as a snake that “must be hit on the head.”
She is now expected to be appointed vice-president at a special congress of the ruling Zanu-PF party next month.
Mr Mugabe called his former deputy a conspirator and warned that he was planning to purge others in the party.
“We knew a long time ago what he [Mnangagwa] was like. But we tried to shield you from it. He thought that by being close to me, I would carry him on my back to the presidency. But I didn’t die, I didn’t resign,” he told his supporters at the headquarters of his Zanu-PF party in Harare.
“We hope we can deal with others who were conspirators alongside him,” he added.
