All praise to the South African Transport and Allied Workers Union, which refused for four days to unload a shipment of Chinese arms destined for landlocked Zimbabwe. That was long enough for a South African court to issue a judgment refusing to let the 77 tons of weapons be transported across the country to Zimbabwe, despite the South African government’s unwillingness to intervene. Robert Mugabe, who has ruled Zimbabwe since independence 28 years ago, is now attempting to steal back last month’s election. Three weeks later the results of the presidential race have still not been published, almost certainly because he lost by a wide margin to opposition leader Morgan Tsvangirai. But Mugabe has already said that there must be a run-off election even before the votes are “recounted”.
