Tsvangirai wants divorce

Zimbabwean Prime Minister Morgan Tsvangirai has called for a "divorce" from his national unity government colleague President Robert Mugabe.



Tsvangirai organised a news conference after his ally, Energy Minister Elton Mangoma, was arrested.



He said the relationship between the parties had broken down and called for elections to be held.



Former foes, Mugabe and Tsvangirai joined in a unity government two years ago after a disputed election.
