Defamation law - Towards politics of substance

In the heat of contest and campaign fatigue, the end justifies the means. When that happens, the aggrieved can only look to the law for redress. I have hence, decided to have a case discussion with you on defamation.  What do we learn from the case of Makgalemele Vs Ya Rona FM 2012 1 BLR 553 HC?

Philip Makgalemele is a former president of the Botswana Football Association (BFA), a Member of Parliament and businessman. His troubles began the day he headed a delegation of the Botswana National Under- 23 team to China. It was in the run-up to parliamentary elections of which he was a candidate.
