British Prime Minister Theresa May said on Tuesday that Mugabe's resignation gave Zimbabwe the chance to forge a new path, free from oppression.
His resignation was announced by the speaker of Zimbabwe's parliament Jacob Mudenda.
Afolabi said that whatever good achievements recorder by Mugabe over the years could no longer be celebrated because of his sit-tight attitude to governance.
"The immediate priority is to ensure that Zimbabwe has a legitimate government; the only way to achieve that goal is through free and fair elections, held in accordance with the constitution". Meanwhile, in South Africa, most Members of Parliament expressed the view that while the military intervention in Zimbabwe must not be celebrated, the people of Zimbabwe should be commended for a peaceful transition.
Lawmakers roared in jubilation and people have begun celebrating in the streets.
Emmerson Mnangagwa, who was recently fired as Mr Mugabe's vice-president, is now expected to take over as the country's leader within 48 hours.
Human rights campaigners hope the end of Mr Mugabe's brutal rule could mark a turning point for Zimbabwe.
"Everybody is crying for our country", he said.
Cde Mugabe resigned as the country's president after 37 years in power on Tuesday afternoon, sparking wild celebrations across the country.
"President Mugabe condoned human rights violations, defended criminal actions of his officials and allowed a culture of impunity for grotesque crimes to thrive".
"It's just one of those conspiracy theories, in Africa once something goes wrong people find solace in blaming the West for it", he said.
"No African should rejoice over the resignation of Comrade Robert Mugabe".
