Zimbabwe's 'crocodile': Emmerson Mnangagwa

Emmerson Dambudzo Mnangagwa, known in Zimbabwe as "ngwena" or "crocodile" because of his political cunning, is now President Robert Mugabe's heir apparent.

The 68-year-old may be more than 20 years Mr Mugabe's junior, but he is steeped in the political intrigues of Zanu-PF, the ruling party which has its roots in the war to end white-minority rule.

Nomsa Maseko reports on the man with a reputation for cruelty, ruthlessness and darting eyes.
