President Robert Mugabe has not been having it easy with his opposition these days, what with them being always on the alert and looking for the slightest slip to use against him.

Last month he was heckled by opposition members whilst delivering the state of the nation address. Somehow, that speech came back into play in this instance.

The President read the wrong speech during the opening of Zimbabwe’s parliament Tuesday, with opposition MP’s quickly picking up on it. Somehow, the 91 year old Mugabe did not pick up on the error and read the speech throughout.

The speech turned out to be the same one he read when he was booed last month.

“The mix-up happened in his secretarial office. Therefore the delivery in Parliament should be set aside,” spokesman George Charamba was quoted as saying by the online edition of the government-owned Herald newspaper.

But the main opposition Movement for Democratic Change (MDC), which is critical of Mugabe’s long rule, said the blunder called into question his fitness to hold office.

“This is a historic blunder. Anyone who is still of a sound mind would have quickly picked it up that the speech was the wrong one,” MDC spokesman Obert Gutu told Reuters.

“But it dovetails with what we in the MDC have been saying that Robert Mugabe is no longer fit for purpose. He should resign,” Gutu said.

Charamba said the proper speech would be read at a later date.

The fun never stops when Uncle Bob is around.
