Zimbabwe is in the grips of a cholera epidemic, with almost 15,000 known cases of the disease according to the UN.

Earlier this week, George Bush, the US president, joined the mounting calls for Robert Mugabe to step down as president of Zimbabwe. But African nations - except for the lone voices of Botswana and Kenya - still insist that political dialogue between Morgan Tsvangirai, the country's opposition leader and prime minister-designate, and Mugabe is the only way forward.

This week, Morgan Tsvangirai joins the show to discuss the situation in Zimbabwe.
