Zimbabwe’s political crisis over presidential succession

Zimbabwe is facing a political crisis with the ruling Zanu-PF party, as a very public showdown over who is likely to succeed President Robert Mugabe plays out.

The current standoff is between the Youth faction, loyal to his wife, Grace Mugabe, and the former liberation fighters, loyal to Emmerson Mnangagwa, the vice president who was fired last week.
