A Zimbabwean parliament committee on Monday again summoned the former Zimbabwean President Robert Mugabe on Wednesday, to rule on the “disappearance” of billions of dollars in revenue from the sale of diamonds.

He is summoned by parliament to explain the disappearance of diamonds worth $15 billion.

The commission of Mines and Energy, Monday, sent a summons to Robert Mugabe. The 94-year-old former president, whose health is fragile, will have to appear before the committee on Wednesday, May 23. It had already been convened last April but the hearing was cancelled. For the moment, Mugabe has not indicated whether he will go to the audition or not.

In this case, several former ministers and heads of law enforcement have already been questioned about their activities in the Marange mine in the east of the country.

Last year, a report by Global Witness accused Zimbabwean leaders of having for a long time diverted the funds from diamond mining to finance the crackdown on political opponents. Started in 2006, Zimbabwe has yet to release credible statistics on its diamond business.

After thirty-seven years of unchallenged power at the head of Zimbabwe, Robert Mugabe left power on 21 November 2017, via a coup by the army and its ruling party, the ZANU-PF. He was replaced a few days later by Emmerson Mnangagwa, his former vice president.
