Mphoko is the Acting President for now..

Vice President Phelekezela Mphoko, by operation of law, became Acting President following the resignation of former President Robert Gabriel Mugabe, but the ruling Zanu-PF has a right to nominate its next substantive leader within 90 days from the day of resignation, legal experts have said.  

Advocate Thabani Mpofu said VP Mphoko was now the Acting President, but Zanu-PF, being the ruling party, must now nominate a substantive successor to Mugabe.

Professor Lovemore Madhuku said Zanu PF could nominate its replacement and advise the Speaker minutes after the resignation.
