Zimbabwe braces for change after Mugabe exit

After nearly 40 years in power, Zimbabwe president Robert Mugabe has resigned. The Zanu PF party has 90 days, according to the constitution, to nominate a replacement for Mr Mugabe. That man appears to be Emmerson Mnangagwa. Eddie Cross is the MP for Bulawayo South and the founder of the opposition party, Movement for Democratic Change, which is led by Morgan Tsvangirai. He joins us to discuss what's expected.
