As Khama leaves SADC...

The chairmanship changeover at SADC is traditionally brief and marked by humour. The outgoing chair hands his successor the ceremonial gavel and block as well as the chairman’s badge, shortly after delivering his farewell address.

Last August, Zimbabwean leader, Robert Mugabe used his farewell address to drag his successor Khama down memory lane, recalling the outrage over Sir Seretse Khama’s marriage to Ruth Williams in 1948 and his own encounters with the late founding president.
