The international media has expressed the fact that Mugabe gave better speeches than Mnangagwa.
The norm at the UNGA is that the people attend the address by the UN President, the address by the President of America and then snub all other world leaders. However, the case was different with Mugabe, whose speech was a great expectation to the UN audience therefore people would fill the auditorium.
However, this is different with ED Mnangagwa whom the audience don’t anticipate much to come from his speech.
