Most of the details of the original accusation have been independently confirmed by the local media and by some analysts. It's a massive scandal here.

Disclaimer: I am a South African journo and know some of the people doing the confirming personally - one even stays on my property in the back cottage. The source may have an agenda but so does the truth.

This is a disappointing comment. Africa is a big place with a diverse and exploitative history. Botswana is higher than Taiwan in the 2010 Transparency International ranking [1].

Regarding your assertion of an agenda by the opposition party, this may well be true but isn't that the whole point of having opposition parties? If not them or a free press, who would you expect to uncover these things?
