Govt probe on Tsvangirai wife's death

Zimbabwe Government wants to investigate white commercial farmers over their alleged involvement in the car crash, state media reports

However, it is the latest attempt to link the crash, which Mr Tsvangirai insists was an accident that might fuel fresh controversy.

Zimbabwe has witnessed a fresh wave of farm invasions targeting the remaining few white commercial farmers and their unions say the disturbances are racially motivated.

Mr Mugabe accuses the white farmers of working with former colonial power Britain and the US to try to topple him from power so as to reverse his land reforms.

The ageing ruler also accused the Mr Tsvangirai's Movement for Democratic Change of being puppets of the West and the white farmers until the party agreed to join him in a unity government last month.

However, in some circles the attempt to link the white farmers to the crash would be seen as trying to shift blame from the real culprits.

The country has a long history of prominent politicians who die in mysterious accidents after falling out of favour with those in power.
