Zimbabwe's Prime Minister Morgan Tsvangirai has suspended cooperation with President Robert Mugabe. The prime minister's MDC party left the unity government following this week's renewed detention of top aide Roy Bennett on suspicion of terrorist activities.

Mr Tsvangirai says his detention shows that the president's ZANU-PF party is a "dishonest and unreliable" coalition partner. Following a ruling by the country's high court, Mr Bennett has since been released on bail. He will to have to appear in court on Monday. Since the two parties agreed a national unity government in February, they have been squabbling over the appointment of key cabinet posts. Mr Tsvangirai has called for early elections if the current crisis is not resolved.
