I thought I was getting away from politics for a while. But I now realise that the vuvuzela is to these World Cup blogs what Julius Malema is to my politics columns: a noisy, but sadly unavoidable irritant. With both Malema and the vuvuzela, their importance is far overstated. Malema: South Africa's Robert Mugabe? I think not. The vuvuzela: an archetypal symbol of 'African culture?' For African civilisation's sake, I seriously hope not.Both are getting far too much airtime than they deserve. Both have thrust themselves on to the world stage through a combination of hot air and raucous bluster. Both amuse and enervate in roughly equal measure. And both are equally harmless in and of themselves — though in Malema's case, it is the political tendency that he represents, and the right-wing interests that lie behind his diatribes that is dangerous. With the vuvu I doubt if there are such nefarious interests behind the scenes; it may upset the delicate ears of the middle classes, both here and at the BBC, but I suspect that South Africa's democracy will not be imperilled by a mass-produced plastic horn.

This week, Zuma was quoted as saying, 'When the British came to our country, they said everything we are doing was barbaric, was wrong, inferior in whatever way.' But the serious critique of Zuma is not about who is a barbarian and who is civilised. It is about good governance, and this is a universal value, as relevant to an African village as it is to Westminster. If you are unable to keep your appetites in check, you are inevitably going to live beyond your means. And this means you are going to become vulnerable to patronage and even corruption. That is why Jacob Zuma's 'polygamy' is his achilles heel.
