Zimbabwe: Tsvangirai says no election without referendum

Zimbabwe Prime Minister Morgan Tsvangirai has said that elections could not take place in his country without reforms and a constitutional review, despite President Robert Mugabe's threat to call one next year. Tsvangirai formed a power-sharing government with Mugabe after disputed 2008 elections, and both promised to work together to reform the Constitution and organise a referendum to approve it before new elections.
